Answer:
1 2/21
Step-by-step explanation:
We start out with:
3/7 + 2/3
In order to add them together, they must have an equal denominator. An easy way to find an equal denominator is the cross method. We divide 7 by 3 and 3 by 7, giving us a denominator of 21:
3/21 + 2/21
But what about the numerators? You do the same thing as before (multiplying by the other's denominator). Now we have:
9/21 + 14/21
We add both together (the denominator stays the same) and we get 23. 23/21 is correct but not in simplest form. We remove 21 from the numerator (because it is a whole) and finally get:
1 2/21!

let me lie down this prism.
Check the picture below.
so the prism is really 6 rectangles stacked up to each other at the edges, so we can simply get the area of each rectangle and sum them up.

when finding volume you're doing the mass/density meaning divide
finding the mass you'll multiply mass and density, finding the density you'll divide mass and volume
Answer:
3 quarters 9 dimes
Step-by-step explanation:
D=dimes
D-6=quarters
0.10 D + 0.25(D-6) = 1.65
0.10D + 0.25D - 1.5 = 1.65
0.35D = 3.15
Dibide both sides by 0.35
D =9
Q= D-6 Q = 9-6 Q=3
9*0.10 =90 3*0.25= 0.75
$0.75 + $0.90 =$ 1.65
