Answer:
5(9b + 8)
Step-by-step explanation:
Rewrite 45 as 5 * 9
Rewrite 40 as 5 * 8
= 5 * 9b + 5 * 8
Factor out common term 5
=5 (9b + 8)
Answer:
<u>1.</u> 20 boxes cost $36. The unit rate is 1:1.8 and when you multiply 1.8 by 5 you get 9. If you also multiply 1.8 by 20 you get 36.
<u>2.</u>He completes 12.5 pages in 200 minutes.
200 divided by 32
multiply that answer by 2
which is 12.5.
hope it helps!
Answer:
y = 3/4x - 2
Step-by-step explanation:
slope intercept form: y = mx + b
y-intercept(when x= 0) is given by b
slope is given by m
lets find the slope using the two given points, (4,1) and (8,4)
m = y2-y1 / x2-x1
m = 4 - 1 / 8 - 4
m = 3/4
Now use any of the given points to begin writing your equation, which will help you find the y intercept - ill use (4,1).
1 = 3/4(4) - b
1 = 3 - b
b = -2
now you have m and b so you can finish writing your equation.
y = mx + b
y = 3/4x - 2
