You have to subtract 4.35 from 15.60 to see for all the children
3x+4.35 = 15.60
In a circle, the parts of the diagonals multiply to equal each other, so 6·4=2x.
2x = 24, x = 12.
Answer:
Step-by-step explanation:
5D-7=38
5D=38+7=45
D=45/5=9
12-3S=48
-3S=48-12=36
S=36/(-3)=-12

128cm^2
Step-by-step explanation:
The length is 16 and the width is 8. 16*8=128.
Answer:
r = 4- 2a/3
In the words of the problem, its r = 4 minus two-thirds a
Step-by-step explanation:
You can set up a general equation for this problem, and then solve for r to get your answer. In this case its:
4a + 6r = 24
Now move 4a to the other side by subtracting 4a from both sides:
6r = 24-4a
Finally, divide both sides by 6 to get:
r = 4- 2a/3
In the words of the problem, its r = 4 minus two-thirds a
