Answer: B. Subtract 28 from both sides
Explanation: You need to subtract first because the variable needs to be by itself.
Answer:
Step-by-step explanation:
This figure is quarter of a circle.
=> Perimeter = π/2r + 2r
=> 5π + 10
=> 5(3.14) + 10
=> 15.7 + 10
=> 26 units
Area = πr²/4
=> 3.14 x 100 / 4
=> 25 x 3.14
=> 79 sq. units
Each board is 4.5 feet long (4 feet and 6 inches.)
Hope this helps!
I think the answer would be be C.
Solution-
Let, total number of t-shirts sold by Ashley= x
since, she made $3 for each t-shirt.
therefore, total profit made by selling x t-shirts= $3x
therefore, Net Profit= (Total Profit made by selling t-shirts)- (total expenditure)
$51=$3x-$27
∴ $3x= $51+$27=$78
∴x =$78/$3=26
Therefore, Ashley needs to sell total 26 t-shirts in order to make a profit of $51.
