Answer:
Equation: 3x - 11 = 85
Solution: x = 32
Step-by-step explanation:
3x - 11 = 85
You will have to do the opposite to the equation shown on the screen.
3x = 96 (85 + 11)
x = 32 (96 / 3)
Answer:27 pieces were sold at the original price.
63 pieces were sold at the new price
Step-by-step explanation:
Let x represent the number of pieces of pottery that was sold at the original price.
Let y represent the number of pieces of pottery that was sold at the new price.
They sold some of their pottery at the original price of $9.50 for each piece. This means that the amount that they got from selling x pieces of pottery at the original price would be 9.5x
They later decreased the price of each piece by $2. This means that the new price was 9.5 - 2 = $7.5
This means that the amount that they got from selling x pieces of pottery at the new price would be 7.5y
If they sold all 90 pieces and took in $729, then the equations are
x + y = 90
9.5x + 7.5y = 729 - - - - - - - - - -1
Substituting x = 90 - y into equation 1, it becomes
9.5(90 - y) + 7.5y = 729
855 - 9.5y + 7.5y = 729
- 9.5y + 7.5y = 729 - 855
- 2y = - 126
y = - 126/- 2 = 63
Substituting y = 63 into x = 90 - y, it becomes
x = 90 - 63 = 27
Answer:
243,58,723,5,334 i'm not really good at putting ,'s in the right place.
the first step is to convert the diameter into a radius measure by using the formula d=2r
when we solve the formula the radius is calculated to be 1.5
use the surface area formula above and your height and radius measurement to find out the area of sheet metal you would need.
2pi(1.5)^2+2pi(1.5)(5)
using 3.14 for pi this equates to 61.23in^2
