Answer:
<em>3n; 2 nickels and 6 quarters</em>
Step-by-step explanation:
"Peggy had three times as many quarters as nickels."
Whatever number of nickels she has, the number of quarters is 3 times as many.
Since she has n nickels, she has 3 times n quarters.
The number of quarters is 3n.
A nickel is worth $0.05, so n nickels are worth 0.05n.
A quarter is worth $0.25, so 3n quarters are worth 0.25(3n).
0.05n + 0.25(3n) = 1.60
0.05n + 0.75n = 1.6
0.8n = 1.6
n = 2
She has 2 nickels.
3n = 3(2) = 6
She has 6 quarters.
Hello!
If the digit to the right is less than 5, you drop it to the left one. If the digit is greater than 5, then you round it to the next decimal. So, here are the answers:
2.6 rounded = 3
1.8 rounded = 2
4.2 rounded = 4
3.3 rounded = 3

Answer:
the y intercept is 6
Step-by-step explanation:
Step 1: Add -4x to both sides.
4x+2y+−4x=12+−4x
2y=−4x+12
Step 2: Divide both sides by 2.
2y
/2 =
−4x+12
/2
y=−2x+6
Points (3,6)
x intercept is 3 and y intercept is 6
