Answer:
15 and np
Step-by-step explanation:
add 5 + 5+ 5
Let:
x= quarters
y= dimes
x+y=67
and
.25x+.10y=12.40
x=67-y
.25(67-y)+.10y=12.40
16.75-.25y+10y=12.40
16.75-.15y=12.40
Lets rearrange this:
-.15y+16.75=12.40
-16.75 -16.75
-.15y=-4.35
the negatives cancel out
.<u>15y</u>=<u>4.35
</u>.15<em /><em> <u /></em>.15
y=29
Back to the original x=67-y
x=67-29
x=38
So,
x=38
y=29

This answer should be the third one
Answer (Respuesta): B
3^2 (9) + 1 = 10 y 2^2 (4) + 1 = 5 por eso 10 - 5 = 5
