You add 13 and 8 it gets 21 so for X its 13
Since it asks you to estimate, you would round the 4.6 up to 5. The estimate volume would be 125 inches^3; answer C.
N + 2d =1
This is the system of equations because it is 2 times more than nickels
Answer:
1 3/8.
Step-by-step explanation:
3 1/4 - 1 7/8
First convert to improper fractions:
3 1/4 = (3*4) + 1 / 4 = 13/4.
1 7/8 = (1 *8)+7 / 8 = 15/8. So we have:
13/4 - 15/8
The Lowest Common Multiple of 4 and 8 is 8 so we convert 13/4 to eighth's
13 / 4 = 13*2 / 4 *2 = 26/8
Finally: we have
26/8 - 15/8 = (26 - 15) /8
= 11 /8
= 1 3/8 (answer)
