Answer:
y = 5x +20
Step-by-step explanation:
We assume you want the total cost (y) of x months of membership at the dance club.
This will be the sum of the start-up fee (20) and the product of the monthly fee (5) and the number of months (x).
y = 5x +20
Comparing this to the slope-intercept form of the equation of a line, we see ...
y = mx + b
m = 5
b = 20
Answer:
w = 15
Step-by-step explanation:
7(w + 3) = 16 + 10(w − 4)
7w + 21 = 16 + 10w - 40
7w + 21 = 10w - 24
-3w = - 45
w = 15
The answer is 1/2. 1/5 is equal to 2/10, and 2/10 + 3/10 = 5/10. 5/10 is equal to 1/2 in simpelst form.
Firstly, we’d have to find the total price paid for erasers by subtracting the overall price from the amount she paid in pencils.
$4.25 - $1.75 = $2.50
From there, we can use the amount per eraser to find out how many erasers she bought. Since she spent $2.50 in erasers, we can multiply to find our missing number.
$0.25 x 10 = $2.50
Therefore, Stefanie bought 10 erasers.
Hope this helps! :)
