Michelle has 2/3 of her monthly allowance left. She plans to save 1/4 of the money she has left . What fraction of the original allowance does she plan to save
Answer: The fraction of the original allowance does she plan to save = [tex]\dfrac16[/tex]
Step-by-step explanation:
Let x = original monthly allowance
Monthly allowance left = [tex]\dfrac23x[/tex]
She plans to save = [tex]\dfrac14[/tex] of (Monthly allowance left)
= [tex]\dfrac14\times\dfrac23x[/tex]
[tex]=\dfrac{2}{12}x\\\\=\dfrac{1}{6}x[/tex]
i.e. the fraction of the original allowance does she plan to save = [tex]\dfrac16[/tex]
In the given figure, ABCD is a rectangle in which ∠APB = 100°. The value of x is:
Answer:
Given that angle APB = 100°
Angle CPB = 180°- 100°. (Angle APB and CPB form a linear pair)
We know all triangles formed here are isosceles
Therefore,
We can take angle PBC= angle PCB = x
Now,
Angle CPB+ x + x = 180°. ( Triangle sum property)
100° + 2x = 180°
2x = 180°- 100°
2x= 80°
x= 80°/2
x= 40°

-5x = 25
what is the answer for x?
Answer:
i think its -5
Step-by-step explanation:
if you devide 25 by -5 you get -5
Answer: x = -5
Step-by-step explanation:
We can use inverse operations to solve the equation. Because the term "-5x" is multiplication (because you are multiplying x by -5), we can use division to solve the equation.
First, we will divide -5 from 25.
25 ÷ -5 = -5.
Because of this, x = -5!
If we're not sure, we can also check the equation.
-5 x -5 = 25, so the answer is true.
In conclusion, x = -5!

So what I'm thinking right. If it costs my pal bob $0.25 for each cupcake and an additional $15 per month we will probably need to variables. So check it
Our positive when we make money is when bob sells cupcakes right? but our negative where bob is spending his money is the $0.25 it cost per cupcake and the $15 a month he also has to pay for expenses
$1.50c-$0.25c-$15.00m
c represents the amount of cupcakes while m represents each month
So if Buddy Boy Bob sold 85 cupcakes in one month lets try to use our equation to solve for profit shall we.
$1.5(85)-$0.25(85)-$15(1)= Bob made about $91.25

write an equation of the line that passes through the points (0,3) and (2,11) y=?
Answer:
y=4x+3
Step-by-step explanation:
find the slope using y2-y1/x2-x1
11-3/2-0
simplify
8/2
simplify
4
find b by using the equation y=mx+b
since we know 4 is the slope, plug it in for m
plug an ordered pair into y=4x+b
3=4(0)+b
3=b
plug b in y=4x+b
y=4x+3

To start a transport company, a business man needs at least 5 buses and 10 minibuses .
He is not able to run more than 30 vehicles all together.
A bus takes up 3 units of parking space, a minibus takes up 1 uni of parking space and there are only 54 units available.
If x and y are the number of buses and minibuses respectively.
a. Write down for inequalities which represents the restrictions of the businessman.
b. Draw a gaph that shows a region representing possible values of x and y.
c. Find the greatest number of:
i. buses
ii. minibuses that the business can run

a) x≥5; y≥10; x+y≤30; 3x+y≤54
b) see attached
c) i. 14 buses; ii. 25 minibuses
Step-by-step explanation:
a. The given restrictions are ...
x ≥ 5 . . . . . . . . . minimum number of buses
y ≥ 10 . . . . . . . . minimum number of minibuses
x + y ≤ 30 . . . . .maximum number of vehicles
3x +y ≤ 54 . . . . maximum number of parking units

The sum of twice a number and 4 times another number is 4. The difference of the numbers is 5. Find the numbers(help a sis out)
Answer:
1st number = 4
2nd number = -1
Step-by-step explanation:
Let n = 1st number
Let m = 2nd number
2n + 4m = 4
n - m = 5
Substitu method, let n = 5 + m
2(5+m) + 4m = 4
10 + 2m + 4m = 4
6m = -6
m = -1
find n:
n - (-1) = 5
n + 1 = 5
n = 4

Step-by-step explanation:
Alfie has £10 note He buys 3 pens costing 1.45 each and some pencils costing 90p He gets 2.05 change. How many pencils did he buy?
Answer:
4 pencils
Step-by-step explanation:
Note= pencils costing 0. 90p
Given data
Balance= £10
pen= 3*1.45= £4.35
pencils=0.90p
change= £2.05
2.05= 10-4.35-90p
solve for p
2.05= 5.65-90p
collect like terms
5.65-2.05= 0.90p
3.6=90p
divide both sides by 90
p=3.6/0.90
p=4

Answer:
there monthly budget is $4000
Step-by-step explanation:
if 600 is 15% then there is 85% of there budget left so in order to find how much is 1% then 600/15=40 so $40 = 1% so 1%x100=100% and 40x100=4000 so 100% of there budget is $4000
hope this helps have a blessed day :)
how do i solve this??
Answer:
J (3; 9)
Step-by-step explanation:
Imagine each distance like a triangle and use Pythagorean theorem.
To illustrate I drew triangle ΔLON in the picture
Finding the distance between LN.
LO = [tex]y_{L} - y_{O}[/tex] = 5 - 1 = 4
NO = [tex]x_{N} - x_{O}[/tex] = 5 - 4 = 1
According to Pythagorean theorem
[tex]LN^{2} = LO^{2} + NO^{2}[/tex]
[tex]LN^{2}[/tex] = [tex]4^{2} + 1^{2}[/tex] = 17
LN = [tex]\sqrt{17}[/tex] (LN > 0)
Since ΔMLN ≅ ΔKLJ, JL = LN (they are clearly equal triangles)
Mark J coordinates as (x; y)
Draw another triangle JOL, ∠JOL = 90°)
OJ is parallel with x axis and OL is parallel with y axis. O coordinates then are (4; y)
OL = y - 5
OJ = 4 - x
Note that ΔLON = ΔJOL, so OL is the same as LO and therefore
OL = LO = y - 5 = 4;
y = 9
OJ = NO = 4 - x = 1
x = 3
So the coordinates of J are (3; 9)
Similarly find the coordinates of K
