Answer:$39
Step-by-step explanation:
The discounted price is going to be 60% of the original price because 100 - 40 = 60. So we want to find 60% of the original price, or 65. 65 x . 6 = 39, so the pair of rollerskates will be $39 at the discounted price.
Answer:
He needs 1 more fish tank.
Step-by-step explanation:
18 / 3 = X (X equals the number of fish tanks he needs)
2 + 3 = 5 fish tanks
5 x 3 = 15 fish
18 -15 = 3
Since 5 fish tanks can hold 15 fish he will need 6 fish tanks to hold his 18 fish. He will need 1 more fish tank.
6 1/2 hours = 6.5 hours
78/6.5=12
My rate of pay is 12$ per hour
37/3 ^2 = 1369/9
15/2 ^2 = 225/4
1369/9 + 225/4 = 7501/36
sqaureroot of 7501/36 = 14.43
so closest to B. 14 3/5

Answer:</h3>
y = -1/2x +(4 1/2)
<h3>
Step-by-step explanation:</h3>
The two marked points (-1, 5) and (1, 4) differ in y-value by -1 and x-value by +2, so the slope is -1/2.
The y-intercept is halfway between the marked y-values, so is at 4 1/2.
Putting these numbers into the slope-intercept form of the equation for a line, ...
... y = mx + b . . . . for slope m and y-intercept b
we have ...
... y = -1/2x +(4 1/2)
