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]

Answer:
The slope of the line is 3 ---> m = 3
Step-by-step explanation:
To find the slope of the line, you can choose any two given points from the table. Let's do (1, 3) and (2, 6)
Slope formula:
m = (y2 - y1) / (x2 - x1)
m = (6 - 3) / (2 - 1)
m = 3 / 1
m = 3
