Answer:
Slope = 
Step-by-step explanation:
Slope of a straight line passing two points 
and 
is given by the formula,
m = 
From the graph attached,
Line is passing through two points (20, 5) and (80, 20),
Therefore, slope of the line will be,
m = 
m =
The slope is .
Answer:
B. 3
Step-by-step explanation:
Let's make an equation for this. Our unknown number is x.
x
We are adding 4.
x + 4
Then multiplying by 5.
(x + 4) • 5
It will equal 35.
(x + 4) • 5 = 35
To solve this, divide both sides by 5.
(x + 4) = 7
Now subtract 4 from both sides.
x = 3
This is your answer.
Check this by plugging it back into our original equation.
(x + 4) • 5 = 35
(3 + 4) • 5 = 35
7 • 5 = 35
35 = 35
Your answer is correct.
Hope this helps!
Divide the number of people by the number of plates per pack:
138 / 12 = 11.5
He need to buy 12 packs of plates to have enough.
40% = 40 / 100 = 0.4
32 is 40% of what
= 32 / 40
= 32 / 0.4
= 80

U can also use this equation to solve it.
32 = 40%x
Simplfy
= 32 = 2/5x
Flib the equation.
2/5x = 32
Multipy both sides by 5/2
(5/2) * 2/5x = (5/2) * 32
x = 80.
