I solved by substitution
Answer:
14 nickels
7 dimes
Step-by-step explanation:
1. find out how many dimes there has to be to get $1.40
1 dime= .10
1.40/.10=14 dimes
14/2=7
so there are 7 dimes
since a nickel is half the amount of a dime there will be twice as many to make up the other half which is $0.70
.70/.05=14
there are 14 nickels
proof:
$0.10(7)+$0.05(14)= $1.40
hope this helps!
Answer:
<h2>r ≤ 0</h2>
Step-by-step explanation:
13 - r ≥ 13 <em>subtract 13 from both sides</em>
13 - 13 - r ≥ 13 - 13
-r ≥ 0 <em>change the signs</em>
r ≤ 0
10x-2y=10 We need to solve this equation for "y" to put it into slope intercept form:
10x-2y=10
-2y = -10x +10 Subtracted 10x from both sides
y = 5x - 5 Divided both sides by -2
y = 5x - 5 Is slope intercept form
