Answer:
9 quarters 5 dimes!
Step-by-step explanation:
9x0.25=2.25
5x0.10=0.50
2.25+0.50=2.75
Isolate the variable by dividing each side by factors that don't contain the variable. p=q/2r
Answer: Choice A. (8, 4)
==========================================================
Explanation:
Because x = 2y, we can replace every copy of x with 2y
Let's do so in the second equation
3x - 4y = 8
3(x) - 4y = 8
3(2y) - 4y = 8 .... x replaced with 2y; now let's isolate y
6y - 4y = 8
2y = 8
y = 8/2 ..... divide both sides by 2
y = 4
Use this y value to find x
x = 2y
x = 2*4
x = 8
So we have x = 8 and y = 4 pair together to get the answer (x,y) = (8, 4) which is choice A.

n = number of problems
Our final answer can't be a decimal, so we round it to:
Answer:
23.3333333333
Step-by-step explanation:
I am sure this is the answer cuz if m= 2 2/3 you just have to add 2 to that, that would make it 4 2/3 and 4 2/3x5 is 23.3333333333
