Answer:
37 dimes and 10 nickels
Step-by-step explanation:
let d = # dimes
let n = # nickels
we can set up a system of equations:
n + d = 47
.05n + .10d = 4.2
if we solve the first equation for 'n' we get:
n = 47-d
now we can substitute this in for 'n' in the second equation:
.05(47-d) + .10d = 4.2
2.35 - .05d + .10d = 4.2
2.35 + .05d = 4.2
subtract 2.35 from each side to get:
.05d = 1.85
d = 1.85÷.05
d = 37
if d+n = 47 and d=37 then n = 10
Check:
.05(10) + .1(37) should equal 4.2
.50 + 3.7 = 4.2 [It Checks Out]

Step-by-step explanation:
Answer:
4 and 5
Step-by-step explanation:
So alternate means there's on different sides of the one line that cuts through both lines, so that would be 1 and 8, 2 and 7, 3 and 6, and 4 and 5. But interior means that it's on the inside, so that would be 3 and 6, and 4 and 5, so 4 and 5 is your answer
hope this helps:)
