12. Make equation and plug in
13. Proportion
14. Finding a constant rate, and then manipulate
12. Where x is miles driven, and y is answer, and z is days
19.95z+0.15x=y
Plug in two values
19.95 x 2 + 0.15 x 250 = y
39.93+37.5 = y
y=77.43
13. 5:2 as 175:x
5/2 = 175/x
x = 70
70+175=245
14. 260:5 = x:1
260/5=x/1
x = 52
52:1 = y:9
52/1 = y/9
y = 468
I hope you understand the process.

Answer:
(3.50 x 3) + (3.00 x 4) = $22.50
Step-by-step explanation:
1. A property a parallelogram must have is that adjacent angles must be supplementary, they add up to 180º. We are given the values of the adjacent angles U and T. Their sum must add up to 180º. Solve for x.
<span>U + T = 180 </span>
<span>5x + 2x - 9 = 180 </span>
<span>7x - 9 = 180 </span>
<span>7x = 189 </span>
<span>x = 27 </span>
<span>Substitute this value of x for itself in angle T. </span>
<span>T = 2(27) - 9 </span>
<span>T = 54 - 9 </span>
<span>T = 45, (D) is the answer </span>
