A is additive equality, where -x and x adds to 0
b is distributive, where x(y+z)=xy+xz
c is multiplicative equality, where x*1=x
d is subtracting both sides by 3.
Answer:
960
Step-by-step explanation:
Over here, I'm going to do it in two ways, and either way works, one is just easier to do out:
1st way:
You can represent the percent 120 as a decimal which is 1.20, then you do 800*1.2.
2nd way:
You can use benchmark percents. You find 10 percent of 800 which is 80 and multiply 80 by 2 to get 160, so 20% is 160 dollars. Then you add 160 to 800 (800+160) and get 960.
Please tell me if you have any questions.
The dimensions are 8 ft x 8 ft.
The total area is 64 sq ft.
The dimensions of a single tile are 2 1/2 x 1 1/2
3.1 , 3.4 , 11 would be your answer's
25 = 5*5
405 = 81*5
therefore, 25/405 = (5*5)/(81*5)=5/81
