Answer:
y = 13.8
Step-by-step explanation:
Plug in 7.2 for x in the first equation.
y = 1.5x + 3
y = (1.5)(7.2) + 3
Simplify. First, multiply, then add (following PEMDAS).
y = (1.5)(7.2) + 3
y = (10.8) + 3
y = 13.8
13.8 is your answer for y.

Answer:
A
Step-by-step explanation:
Find the slope using rise/run
This gets you -5/4
Find the y intercept, which is at (0, 3)
This means the equation will be:
y = -5/4x + 3
It’s quite simple, -6.8/-7.4
a negative with a negative will become a positive
answer:
0.91891891891
well, we know his rate is 6/5 lawns/hour that means he can do 6 lawns in 1 hour, well, how many can he do in 50 hours?
![\bf \begin{array}{ccll} lawns&hours\\ \cline{1-2} 6&5\\ x&50 \end{array}\implies \cfrac{6}{x}=\cfrac{5}{50}\implies \cfrac{6}{x}=\cfrac{1}{10}\implies 60 = x](https://tex.z-dn.net/?f=%5Cbf%20%5Cbegin%7Barray%7D%7Bccll%7D%20lawns%26hours%5C%5C%20%5Ccline%7B1-2%7D%206%265%5C%5C%20x%2650%20%5Cend%7Barray%7D%5Cimplies%20%5Ccfrac%7B6%7D%7Bx%7D%3D%5Ccfrac%7B5%7D%7B50%7D%5Cimplies%20%5Ccfrac%7B6%7D%7Bx%7D%3D%5Ccfrac%7B1%7D%7B10%7D%5Cimplies%2060%20%3D%20x)
Do PEMDAS! Multiply and divide from left to right. 123456789 x 125 is 15432098625, and now we divide by 4, giving us 3858024656.25, but rounded to the nearest whole number (ones) is 3858024656.
Hope this helped!
