2.8y + 6 + 0.2y = 5y – 14
Start by simplifying the left side:
3y + 6 = 5y - 14
Next, deduct 3y from both sides:
6 = 2y - 14
Add 14 to both sides:
2y = 20
Now, divide by 2:
y = 20 / 2
y = 10
The correct choice is c because her earnings total $240.
Response:
D
Step-by-step explanation:
5q + 2d = 270
To determine the intercepts, start by setting d to 0, then to find q. The conditions yield:
5q = 270
q = 54; (0, 54)
2d = 270
d = 135; (135, 0)
This equation illustrates the total number of coins in the piggy bank. For (0, 54), this indicates the quantity of quarters when dimes are absent, while (0, 135) displays the number of dimes when there are no quarters.
