Use proportions because we know that the triangles are similar.

Cross multiply.
20x=28×5
x=7
answer: 7
Answer:
53 Rolls of paper and 56 Candles
Step-by-step explanation:
56 x $10 = $560
$7 x 53 = $371
$560 + $371 = $931
And 56 candles sold plus 53 rolls of paper sold equals 109 items sold
X=3x-2.4 because if you substract from one side you have to do it to the other
Slope intercept form is y = mx + b...ur slope will be in the m position and ur y int will be in the b position
examples : slope = 2 , (1,3)....x = 1 and y = 3
y = mx + b
slope(m) = 2
(1,3)...x = 1 and y = 3
now we sub and find b, the y int
3 = 2(1) + b
3 = 2 + b
3 - 2 = b
1 = b
so in slope intercept form, ur equation is : y = 2x + 1
================
another example : slope = 3 , (-2,-4)
y = mx + b
slope(m) = 3
(-2,-4)...x = -2 and y = -4
now sub and find b, the y int
-4 = 3(-2) + b
-4 = - 6 + b
-4 + 6 = b
2 = b
so ur equation is : y = 3x + 2
