2 pounds each
Answer:
12 dimes and 18 nickels
Step-by-step explanation:
Equations given by word problem:
n + d = 30
0.05n + 0.1d= 2.10
How I solved them:
d= 30 - n
0.05n + 0.1(30 - n)= 2.10
0.05n + 3 - 0.1n= 2.10
-0.05n= -.09
Divide both sides by -0.05
n= 18
18 + d = 30
d= 12
8 mi. 133 yd. 2 ft. - 5mi. 107 yd. 2 ft.
= (8 mi. - 5 mi.) + (133 yd. - 107 yd) + (2 ft. - 2ft.)
= 3 mi. +26 yd.
<h3>= 3 mi. 26 yd.</h3>
3 6/10÷ 9
36/10×1/9
36/90
.4<1
(Less than)
Hope this helps!
