How many solutions does the equation have?
1 answer:
9514 1404 393
Answer:
1 solution
Step-by-step explanation:
The coefficients of d are different on the two sides of the equation (3d vs 6d), so the equation has one solution.
__
Dividing by 3 gives ...
d +11 = 2(d +33)
d + 11 = 2d + 66
Adding -d-66 to both sides gives ...
-55 = d . . . . . . the one solution

Answer:
I would say B not sure tho
It would be 330 if rounded to the nearest 10th place
She can expect 10 2-dollar-off coupons or C.
S = 3+M
4(S + M) = 67
4(3+M + M) = 67
4(3+2M) = 67
12 + 8M = 67
8M = 55
M = 6 years 10 months 14 days @ 6.875 years
S = 3 + 6.875
S = 9 years 10 months 14 days
