So we need to represent the problem using an equation
900 = the original pile of bricks (x) + 25% more - 40% (original + 25% extra)
900 = x + .25x - .4(x + x*.25)
900 = x + .25x - .4x - .1x
900 = .75x
x = 1200
∠4 is also 75 (interior opp angles)
Answer:
51
Step-by-step explanation:
24 ^2+45^2=x^2
=51
Answer:
m = 5
Step-by-step explanation:
Let's convert 5x - y = 20 to slope-intercept format: y = mx + b
5x - y = 20
-y = -5x + 20
y = 5x - 20
Now, we can input the y-value(5) to find the x-value(m)
5 = 5m - 20
25 = 5m
m = 5
