0=7x+14-4
0=7x+12
7x=-12
x=-12/7
Answer:
D
Step-by-step explanation:
Since 5 is being multiplied with q dividing both sides by 5 would cancel out the 5 from 5q leaving us with q and on the other side of the equal sign 5/7 or 1.4 is going to be the value of q
F and D is the answer
hope this helps
have a good day
2*2*2= 8
13*1= 13
2*3*5=30
2*5*5= 50
Number of tests made =x
Verzon C(x) = 45 + 0.1x => 45+0.1*1200 =165
AT & T C(y) = 30 + 0.13x=> 30 + 0.13*1200=186
For 1200 texts C(x) is less than C(y)
If the costs are to be the same then
45 + 0.1x = 30 + 0.13x
15=0.03x
15/0.03= x
500=x
