X + y = 37
5x + 10y = 330
STEP ONE:
Substitute the variables
x = 37 - y
STEP TWO:
Substitute the values
5(37 - y) + 10y = 330
STEP THREE:
Multiply
185 - 5y + 10y = 330
STEP FOUR:
Subtract 185 from both sides
-5y + 10y = 145
STEP FIVE:
Add
5y = 145
STEP SIX:
Divide
y = 29
STEP SEVEN:
Check
x = 37 - 29
x = 8

Therefore, Angela has 8 nickels and 29 dimes.

GenaCL600 [577]

Answer:

177 pounds

Step-by-step explanation:

Create an equation to represent the system.

Since it's 18% more than what was used last month an equation can be written such as the one below:

(118%)( last month's cheese ) = this month's cheese

Convert the percentages into decimals by moving the decimal place at the end of 118.00 two places to the left

118% = 1.18

( 1.18 )( last month's cheese ) = this month's cheese

Next, plug in the number for last month's cheese

( 1.18 )( 150 pounds) =

177 pounds
