Ur equations are :
C = 0.03t + 20...this is company A
C = 0.07t + 5....this is company B
now...for them to be equal...set them equal and solve for t
0.03t + 20 = .07t + 5
-5 + 20 = 0.07t - 0.03t
15 = 0.04t
15/0.04 = t
375 = t.......there would have to be 375 texts
Answer:
x = 7
Step-by-step explanation:
The angle adjacent to the 70 degree angle is also 70 degrees. We assume that there are four 90-degree angles in the center of the figure. Thus, 8x - 36 + 70 + 90 = 180 (the sum of the interior angles is 180 degrees).
Solving 8x - 36 + 70 + 90 = 180 for x:
8x - 36 = 20, or 8x = 56.
Dividing both sides by 8 yields x = 7.
Answer:
D. 77 + 8
Step-by-step explanation:
7 x 8 = 56
now try the other problems
A. 6 x 8 = 48
B. 6 x 7 = 42
C. 7 x 7 = 49
D. 77 + 8 = 56
D is the answer
