Answer:
[tex]\frac{22}{30} = \frac{11}{15}[/tex]
and
[tex]\frac{176}{7} = 25 \frac{1}{7}[/tex]
Step-by-step explanation:
First make all the fractions into improper fractions
[tex]1\frac{5}{6} = \frac{11}{6} \\\\2\frac{1}{2} = \frac{5}{2} \\\\3\frac{1}{7} = \frac{22}{7}[/tex]
After doing that put them back into the problems
Problem 1)
[tex]1\frac{5}{6}[/tex] ÷ [tex]2\frac{1}{2}[/tex] , plug in the improper fractions
[tex]\frac{11}{6}[/tex] ÷ [tex]\frac{5}{2}[/tex]
to divide, you need to flip the second fraction and multiply
[tex]\frac{11}{6}[/tex]· [tex]\frac{2}{5}[/tex] = [tex]\frac{22}{30}[/tex]
then reduce
[tex]\frac{22}{30} = \frac{11}{15}[/tex]
Problem 2)
[tex]3\frac{1}{7}[/tex]÷ [tex]\frac{1}{8}\\[/tex]
Plug in improper fraction
[tex]\frac{22}{7}[/tex] ÷ [tex]\frac{1}{8}\\[/tex]
Then flip second fraction and multiply
[tex]\frac{22}{7}[/tex] · [tex]\frac{8}{1}[/tex]
Multiply
[tex]\frac{176}{7}[/tex]
Reduce, or make it a mixed number
[tex]\frac{176}{7} = 25 \frac{1}{7}[/tex]

How many sides does the polygon have?
1) 20
2) 8
3) 36
4) 10
Answer:
36
Step-by-step explanation:
Given that :
Rotation about polygon's center = 20°
To carry the polygon onto itself Angle of rotation is obtained by :
360° / n
Where n is the number of sides in the polygon :
360° / n = 20°
360° = 20 * n
360 = 20n
n = 360 / 20
n = 18
Hence, the polygon has 18 sides or a multiple of 18

Solve the system of linear equations by substitution. 3x-4y=12 x=-2y+4
Answer:
x=4, y=0. (4, 0).
Step-by-step explanation:
3x-4y=12
x=-2y+4
-----------
3(-2y+4)-4y=12
-6y+12-4y=12
-10y=12-12
-10y=0
y=0/-10=0
x=-2(0)+4=0+4=4
Answer:
Step-by-step explanation:
if x=-2y+4
3x-4y=12 becomes
3(-2y+4)-4y=12
-6y+12-4y=12
-10y+12=12
-10y=0
y=0
since x=-2y+4
x=-2(0)+4
x=4
so the solution is the point (4,0)
38. A football pitch measuring 120m by
80m is surrounded by a running track
measuring 15m wide all round. Find
area covered by the running track
Answer:
Area of the running track = 6900 m²
Step-by-step explanation:
Length of a football pitch = 120 m
Width of the football pitch = 80 m
Area of the football pitch (Inner rectangle) = Length × Width
= 120 × 80
= 9600 m²
If a running track (width = 15 m) is built around the football pitch,
Length of the outer rectangle = 120 + 2×(15)
= 120 + 30
= 150 m
Width of the outer rectangle = 80 + 2×(15)
= 110 m
Area of the outer rectangle = 150 × 110
= 16500 m²
Therefore, area of the track around the football pitch = Outer rectangle - Inner rectangle
= 16500 - 9600
= 6900 m²
Area of the running track = 6900 m²

Answer:
angle 2 = 133
angle 3 = 47
Step-by-step explanation:
angle 2 and angle 1 are supplementary, so they equal 180. 180- 47=133
angle 3 and angle 4 are supplementary, so they equal 180. 180- 133=47

You can't do anything about the numbers with variables afterwards, so you just list those and you just add and subtract the numbers without variables. Since the top and bottom are the same, you just list it once. Sorry, not the best explanation. Please let me know if I am wrong. It's been a while since I had to any type of algebra.
write the slope intercept form of the equation with the given slope and y-intercept.
1. Slope= -10, y- intercept = -5 2. Slope= - 9/5, y- intercept = -4
3.Slope= -5/4, y- intercept = 5 4. Slope= 7, y- intercept = 5

2. [tex]y = \frac{9}{5}x - 4[/tex]
3. [tex]y = -\frac{5}{4}x + 5[/tex]
4. y = 7x + 5
Step-by-step explanation:
use y = mx + b
m = slope
b = y-intercept
1. Slope= -10, y- intercept = -5
y = -10x - 5
2. Slope= - 9/5, y- intercept = -4
[tex]y = \frac{9}{5}x - 4[/tex]
3. Slope= -5/4, y- intercept = 5
[tex]y = -\frac{5}{4}x + 5[/tex]
4. Slope= 7, y- intercept = 5
y = 7x + 5

What is a number that when you multiply it by 0.9 and
subtract 6.3 from the product, you get 4.5?
The number that when you multiply it by 0.9 and subtract 6.3 from the product, you get 4.5 is 12.
What is an expression?An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the like terms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example:
1 + 3x + 4y = 7 is an expression.
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
Let the number be x.
According to the problem, we have:
0.9x - 6.3 = 4.5
Adding 6.3 to both sides, we get:
0.9x = 10.8
Dividing both sides by 0.9, we get:
x = 12
Therefore,
The number we're looking for is x = 12.

A group of nine friends po to a baseball game. Each friend buys either a hamburger or hot dag
at the game
The group buy 6 hot dogs and 3 hamburgers for a total of $27.75.
• A hamburger costs $1.75 more than a hot dog.
What is the cost of a hamburger?
Answer: $4.25
Step-by-step explanation:
Let the cost of the hotdog be x
Since a hamburger costs $1.75 more than a hot dog. Then, the cost of the hamburger will be:
= x + 1.75
We are further told that the group buy 6 hot dogs and 3 hamburgers for a total of $27.75. This can then be represented in an equation as:
6 hot dogs + 3 hamburger = $27.75
(6 × x) + 3 × (x + 1.75) = 27.75
6x + 3x + 5.25 = 27.75
9x = 27.75 - 5.25
9x = 22.50
x = 22.50/9
x = 2.50
The hotdog cost $2.50
Cost of hamburger = x + 1.75
= $2.50 + $1.75
= $4.25

The school sells 240 cookies. ¼ of the cookies had chocolate chips, ½ of the remaining cookies had raisins, and the rest were peanut butter. How many cookies were peanut butter?
Answer:
90 peanut butter

Total number of cookies [tex]=240[/tex]
Number of chocolate cookies [tex]=\frac{1}{4}(240)=60[/tex]
Therefore,
Number of remaining cookies [tex]=240-60=180[/tex]
Number of raisins [tex]=\frac{1}{2}(180)=90[/tex]
