Step-by-step explanation:
Hope this helps :)
−12(7z+4)+15(5z−15)
= -3(4(7z+4)-5(5z-15)
= -3(28z+16-25z+75)
= -3(3z+91)
Answer:
subtract 5 from each side z=2
Step-by-step explanation:
Answer:
$5700 - $5500= $200
Explanation:
The total installments: 24 ($175) = $4200

The amount saved by paying cash: $5700 - $5500= $200
The slope-intercept form of a line:

We have:

Substitute:


Put the values of coordinates of the point (1, 5) to the equation of a line:

Answer: 
Answer:
x = 11
The value "11" makes the equation true.
2 ( x - 5 ) = 12
2 ( 11 - 5 ) = 12
2 ( 6 ) = 12
12 = 12
