He has <150 (hope that's what you're looking for!)
Solve for x:5 x + 3 (x + 4) = -20
3 (x + 4) = 3 x + 12:3 x + 12 + 5 x = -20
Grouping like terms, 5 x + 3 x + 12 = (5 x + 3 x) + 12:(5 x + 3 x) + 12 = -20
5 x + 3 x = 8 x:8 x + 12 = -20
Subtract 12 from both sides:8 x + (12 - 12) = -12 - 20
12 - 12 = 0:8 x = -20 - 12
-20 - 12 = -32:8 x = -32
Divide both sides of 8 x = -32 by 8:(8 x)/8 = (-32)/8
8/8 = 1:x = (-32)/8
The gcd of -32 and 8 is 8, so (-32)/8 = (8 (-4))/(8×1) = 8/8×-4 = -4:Answer: x = -4
Its 1/2 hope it helped you.
It should take 1.75 minutes to run it 1.5 times
that is 1 and 3/4 minutes
A. 5
B. -3/1
C. Negative
D. You have to go down 3 over to the right one from where your y-intercept is.
To plot the y intercept plot (0,5)
To plot the next point go down 3 over 1 to the right from the y-ing
