Answer:
x = 3
Step-by-step explanation:
5(x+1) = 20
x+1 = 20/5
or, x+1 = 4
or, x = 4-1
so, x = 3
It costs £420 for six tickets how much would 5 tickets be
4x-10+1.5x-4x+11=8.5-6
Answer:
x=1
Step-by-step explanation:
4x-10+1.5x-4x+11=8.5-6
Combine like terms
1.5x+1=2.5
Subtract 1 from each side
1.5x+1-1=2.5-1
1.5x = 1.5
Divide by 1.5
1.5x/1.5 = 1.5/1.5
x=1
Answer:
x=1
Step-by-step explanation:
Given :
4x-10+1.5x-4x+11=8.5-6
4x+1.5x-4x=8.5-6-11+10
1.5x=1.5
x=1
Value of x=1

Kendra bought a gallon of milk and StartFraction 5 over 6 EndFraction of a pound of oranges. If the gallon of milk cost $3.60 and she spent a total of $4.35, which equation can be used to determine x, the cost of a pound of oranges?
3.60 + StartFraction 5 over 6 EndFraction x = 4.35
4.35 + StartFraction 5 over 6 EndFraction x = 3.60
3.60 x + StartFraction 5 over 6 EndFraction = 4.35
4.35 x + StartFraction 5 over 6 EndFraction = 3.60
Answer:
A. 3.60+5/6x=4.35
Step-by-step explanation:
Total cost = milk + price per pound of oranges* number of pounds
We know the total cost = 4.35 and the cost of the milk = 3.60 and the number of pounds of oranges = 5/6
4.35 = 3.6 +5/6 * x

One-fourth x minus one-half y = 8
One-half x + three-fourths y = negative 5
(–8, –12)
(–8, 12)
(8, 12)
(8, –12)
Answer:
(8 - 12 )
Step-by-step explanation:
Given
[tex]\frac{1}{4}[/tex] x - [tex]\frac{1}{2}[/tex] y = 8
[tex]\frac{1}{2}[/tex] x + [tex]\frac{3}{4}[/tex] y = - 5
Multiply both equations through by 4 to clear the fractions
x - 2y = 32 → (1)
2x + 3y = - 20 → (2)
Multiplying (1) by - 2 and adding to (2) will eliminate the x- term
- 2x + 4y = - 64 → (3)
Add (2) and (3) term by term to eliminate x
0 + 7y = - 84
7y = - 84 ( divide both sides by 7 )
y = - 12
Substitute y = - 12 into either of the 2 equations and solve for x
Substituting into (1)
x - 2(- 12) = 32
x + 24 = 32 ( subtract 24 from both sides )
x = 8
solution is (8, - 12 )
Answer:D:(8,-12)

Step-by-step explanation:
Determine the location and values of the absolute maximum and absolute minimum for given function : f(x)=(‐x+2)4,where 0<×<3
Answer:
Where 0 < x < 3
The location of the local minimum, is (2, 0)
The location of the local maximum is at (0, 16)
Step-by-step explanation:
The given function is f(x) = (x + 2)⁴
The range of the minimum = 0 < x < 3
At a local minimum/maximum values, we have;
[tex]f'(x) = \dfrac{(-x + 2)^4}{dx} = -4 \cdot (-x + 2)^3 = 0[/tex]
∴ (-x + 2)³ = 0
x = 2
[tex]f''(x) = \dfrac{ -4 \cdot (-x + 2)^3}{dx} = -12 \cdot (-x + 2)^2[/tex]
When x = 2, f''(2) = -12×(-2 + 2)² = 0 which gives a local minimum at x = 2
We have, f(2) = (-2 + 2)⁴ = 0
The location of the local minimum, is (2, 0)
Given that the minimum of the function is at x = 2, and the function is (-x + 2)⁴, the absolute local maximum will be at the maximum value of (-x + 2) for 0 < x < 3
When x = 0, -x + 2 = 0 + 2 = 2
Similarly, we have;
-x + 2 = 1, when x = 1
-x + 2 = 0, when x = 2
-x + 2 = -1, when x = 3
Therefore, the maximum value of -x + 2, is at x = 0 and the maximum value of the function where 0 < x < 3, is (0 + 2)⁴ = 16
The location of the local maximum is at (0, 16).
A water tank has a dimension 3 m long, 1.8 m wide and 2.2 m
high. It has a capacity of:
Answer:
The answer is 11.8 m
Step-by-step explanation:
Hey Mate,
the volume of a cuboid is = whl....so the volume of it is the capacity of the tank
so 3 x 1.8 x 2.2 = 11.88 m is the answer
Nishi invests £4700 at 6% interest per year. Work out how much she will have altogether after: 2 years- £ 5 years- £ 7 years- £ 10 years- £
Answer:
Step-by-step explanation:
To calculate the compound interest we want to multiply the amount of money (£4700) by the interest (6%) which would be the percentage multiplier!
To get the new amount we do:
Original amount × (percentage multiplier)ⁿ
The amount of years would be the indices.
For the first year:
£4700x1.06= £4982.
But we want to find out how much she will have altogether in different years.
So for two years:
£4700x1.03²= £5280.90 (rounded)
As you can see the amount of years will be the indices with the interest as our multiplier.
We do this again for 5 years and 10 years:
£4700x1.06⁵= £6289.70 (rounded)
£4700x1.06¹⁰=£8416.20 (rounded)
Hope this helps!

If IK is the whole length of the line segment, then IJ + JK = IK.
IJ + JK = IK
(3x - 5) + (2x - 1) = (3x + 2)
3x + 2x - 5 - 1 = 3x + 2
5x - 6 = 3x + 2
2x - 6 = 2
2x = 8
x = 4
Now that we know the value of x, we can plug this value back into the expression for JK and evaluate.
JK = 2x - 1
JK = 2(4) - 1
JK = 8 - 1
JK = 7
Hope this helps!

Answer:
-(a)^2 + a - 11
Step-by-step explanation:
N - T = -3(a)^2 + 2a - 5 - (-2(a)^2 + a + 6)
= -3(a)^2 + 2a - 5 +2(a)^2 - a - 6
= -3(a)^2 + 2(a)^2 + 2a - a - 6 -5
= -(a)^2 + a - 11
Given the system of equations.
{-4x+y = 3
{2x - y = 12
Which of the options represents the resulting equation after an equivalent expression for y ls substituted into the
second equation.
2x - (4 X+3) = 12
-4(4y+)+y=3
2 (4x+3) - y
-4x+4 x-3=3
Answer:
A. 2x - (4x + 3) = 12
Step-by-step explanation:
A. 2x - (4x + 3) = 12
B. -4(4y+)+y=3
C. 2 (4x+3) - y
D. -4x+4 x-3=3
Given equation:
-4x+y = 3. (1)
2x - y = 12. (2)
From (1)
y = 3 + 4x
Substitute y = 3 + 4x into (2)
2x - y = 12 (2)
2x - (3 + 4x) = 12
Or
2x - (4x + 3) = 12
2x - 4x - 3 = 12
- 2x = 12 + 3
- 2x = 15
x = 15/-2
x = -7.5
Substitute x = -7.5 into (1)
-4x+y = 3 (1)
-4(-7.5) + y = 3
30 + y = 3
y = 3 - 30
y = -27
1. Harsha makes a scale drawing of a window. She uses the scale 1cm represents 20cm.
A).on her drawing the window is 6cm wide. How wide is the window in real life?
B).The window in real life is 2.2m high. How high is the window on the scale drawing?
Give your answer in centimeters.
Part (A)
(1 cm)/(20 cm) = (6 cm)/(x cm)
1/20 = 6/x
1*x = 20*6
x = 120
120 cm = 120/100 = 1.2 m
Answer: 1.2 m=========================================================
Part (B)
2.2 m = 2.2*100 = 220 cm
(1 cm)/(20 cm) = (x cm)/(220 cm)
1/20 = x/220
1*220 = 20*x
20x = 220
x = 220/20
x = 11

The table shows the game scores of five players. Andy’s brother, Kevin, also plays and gets a score of 9. Find the mean, median, and mode of the data in the table. Then, find the mean, median, and mode of the data in the table and Kevin’s score.
Answer:
The third one
Step-by-step explanation:
Median - Middle number in terms of value
Mode - outcome that appears the most
Mean - average ( add the numbers together and divide that by the amount of numbers )
Data without Kevins score
13, 21, 28, 9, 31
First let's find the mean
To find the mean we simply add the numbers up and divide that by the total amount of numbers ( there are 5 numbers )
13 + 21 + 28 + 9 + 31 = 102
102/5=20.4
So the mean without Kevins score is 20.4
Next let's find the mode
The mode is the number that appears the most
Looking at the data no number appears more than once so there is no mode
Finally let's find the median.
To make it easier to find let's list the numbers in order from least to greatest
9, 13 , 21 , 28, 31
We then go to the middle number ( which would be 21 )
The mode is 21
So for data without Kevins score the mean would be 20.4, the median would be 21 and the mode would be none
Now let's add in Kevin's score and repeat this process
Data with Kevin's score
13, 21, 28, 9, 31, 9
First let's find the mean
( Note that there is 6 numbers this time )
13 + 21 + 28 + 9 + 31 + 9 = 111
111/6 = 18.5
So mean with Kevin's score = 18.5
Next let's find the mode
The number 9 appears the most so the mode is 9
Finally let's find the mean
Once again let's list the numbers from least to greatest
9, 9, 13 , 21 , 28, 31
Because there is an even amount of numbers we will take the sum of the two middle numbers and divide that by 2
The two middle numbers would be 21 and 13
21 + 13 = 34
34/2=17
So median = 17
In the end we get the following
Without Kevins score
Mean = 20.4
Median = 21
Mode = none
With Kevin's score
Mean = 18.5
Median = 17
Mode = 9
This information corresponds with the third table
Evaluate.
3·(7-3)²=?
find the measure of the missing angle (#4 btw)
Answer:
Step-by-step explanation:
1)
∠1 = ∠2 {Angles opposite to equal angles are equal}
∠1 = ∠2 = x
x +x + 55 = 180 {angle sum property of triangle}
2x + 55 = 180
2x = 180 - 55
2x = 125
x = 125/2
x = 62.5
∠1 = 62.5
2) ∠2 = 62.5
3) ∠3 = 55 {Vertically opposite angles are congruent}
4) ∠4 + 105 = 180 {linear pair}
∠4 = 180 - 105
∠4 = 75
5) ∠3 + ∠4 + ∠5 = 180 {Angle sum property of triangle}
55 + 75 +∠5 = 180
130 + ∠5 = 180
∠5 = 180 - 130
∠5 = 50
