Answer:
Step-by-step explanation:
ky-bf = fy/m
Ky - bf = fy/m
Multiply each term by m
Kym - bfm = fy
Collecting y
Kym - fy = bfm
y(km - f) = bfm
y = bfm/(km-f)
Answer:
About 11.10 if it is 315. However it is about 10.95 if it is 313
Step-by-step explanation:
False, think of quarters it would be 0.25
x = the granddaughter's age x + 2 = the grandson's age
x + x + 2 ≥ 12 Collect like terms.
2x ≥ 12 Divide both sides by 2.
x ≥ 6 years
x + 2 ≥ 8 years
