Umm is it a multiple choice question?
Answer:
$21.29 per dancer
Step-by-step explanation:
The materials cost $373.78 for all 22 dancers, so the cost per dancer is ...
$373.78 / 22 = $16.99
Adding the $4.30 cost of gloves to that brings the total for each dancer to ...
$16.99 +4.30 = $21.29 . . . . for each dancer
Answer:
Subtraction property of equality
Step-by-step explanation:
Given the equation;
2x + (x+5) = 41
open the parenthesis;
2x+x + 5 = 41 (Associative property)
3x+5 = 41
Subtract 5 from both sides
3x + 5 = 41
3x + 5- 5 = 41 - 5 (Subtraction property of equality)
3x = 36
Divide both sides by 3;
3x/3 = 36/3
x = 12 (Division property of equality)
Hence the required property is Subtraction property of equality

Answer:
no solution
Step-by-step explanation:
Given equation:
3(2x + 4) - 8x = -2(x + 1) + 3
Expand the brackets:
⇒ 3(2x) + 3(4) - 8x = -2(x) - 2(1) + 3
⇒ 6x + 12 - 8x = -2x - 2 + 3
Collect like terms:
⇒ 6x - 8x + 12 = -2x - 2 + 3
Combine like terms:
⇒ -2x + 12 = -2x + 1
Subtract 12 from both sides:
⇒ -2x + 12 - 12 = -2x + 1 - 12
⇒ -2x = -2x - 11
Add 2x to both sides:
⇒ -2x + 2x = -2x +2x - 11
⇒ 0 = -11
The sides are not equal, therefore there is <u>no solution</u>
