Answer:
30
Step-by-step explanation:
The perimeter of this rectangle is calculated by adding width to length and that multiplied by 2
2*(3x+2x+2) = 54 do inside the parenthesis first
2*(5x+2) = 54 multiply inside the parenthesis by 2
10x + 4 = 54 subtract 4 from both sides
10x = 50 divide both sides by 10
x = 10
The length for PS is 3x
3*10 = 30
Answer to number 6 is D because to compare you need to add zeros to the end for ex.(.4_.78 = .40_.78
Answer:
B
Step-by-step explanation:
Remark
The order is not quite correct.
- 7 + (-11 * 5 - - 7) ÷ - 6
The - - 7 becomes a plus
- 7 + (- 55 + 7) ÷ -6
This is where the real problem is. -55 + 7 goes down. This gives - 48
- 7 + [( - 48) ÷ - 6]
You do the division by - 6 before adding. Adding - 7 to the result of the division is your very last step. Think BedMas.
-7 + (8)
The 8 is the result of the division. -48/-6 = 8. the -7 and the 8 are added. You get 1.
