Answer:
Step-by-step explanation:
d=2q, q=d/2
10d+25q=630, using q=d/2
10d+25d/2=630
20d+25d=1260
45d=1260
d=28
So he has 28 dimes.
Answer:
B
Step-by-step explanation:
To evaluate (f ￮ g)(- 4), first evaluate g(- 4) then substitute this value into f(x)
g(- 4) = 3(- 4) - 5 = - 12 - 5 = - 17, then
f(- 17) = 4(- 17) + 7 = - 68 + 7 = - 61 → B
Answer:
Kim is 3, Tom is 12
Step-by-step explanation:
4x + x = 15
combine like terms
5x = 15
divide both sides by five
x = 3
The answer is 1/14. -3/7 x -1/6. 3 crosses 6 2 time so you are left with -1/7 x -1/2 that is 1/14
