You will need 82 1/4 1/2 tiles and 165 1/4 tiles
Yes, you multiply the numerator by the numerator and the denominator by the denominator
Answer:
7*6-x
or
42-x
Step-by-step explanation:
decrease means subtraction,
product means multiplication
let x be the number you are decreasing by.
I am not really sure how to explain this, but here I go.
you take away x from the number that equals 6*7.
6*7 is 42 and you take away x from that, you get 42-x
or if you want to leave it unsimplified,
6*7-x
1. 4x= 3(18-3x) - 2
4x=54-9x-2
4x+9x=52
13x=52
x=4
substitute 4 for x
4(4)=3y-2
16=3y-2
16 + 2 = 3y
y=6
So your x would be 4 and y would be 6
to check your solution substitute x and y
4(4)=3(6) - 2
16 = 16
Therefore that's the final answer for number 1.
