0.25q + 0.10d = 1.25
q + d = 8....q = 8 - d
0.25(8 - d) + 0.10d = 1.25
2 - 0.25d + 0.10d = 1.25
-0.25d + 0.10d = 1.25 - 2
-0.15d = - 0.75
d = -0.75/-0.15
d = 5 <=== there are 5 dimes
q + d = 8
q + 5 = 8
q = 8 - 5
q = 3 <=== there are 3 quarters
No it doesn't form a proportion
The answer is 9.37 when it is rounded up.
if i helped can i get a brainiest answer please
Answer:
b = (c - 2a) / 5
Step-by-step explanation:
1/2(4a + 10b) = c
2a + 5b = c
5b = c - 2a
b = (c - 2a) / 5
Answer:
The volume of a cylinder is: π × r2 × h
The volume of a cone is: 1 3 π × r2 × h
Step-by-step explanation:
the diference is that the first step of a cylinder is π and the first step of the cone is 1 3 π
the similarities is that The second and 3rd step of the volume of a cylinder is <em><u>r2 × h</u></em><em> </em><em>as well for the cone </em>
<em>hope this helps</em>
