Answer:
15π/4
9π /4
Step-by-step explanation:
= 5 ((-π/4)+ π) = 5 (π-π/4) = 5(3π/4) = 15π/4
= 5(π/4 + 2π) = 5(9π /4) = 45π/4
Answer:
5
Step-by-step explanation:
this is basic algebra so it's important to understand this concept now. you need to combine like terms so 3x-6=9 becomes 3x=15 (you add the 6 to add like terms). You then divide the 3 from 3x on both sides to get x=5
Answer:
A handyman need 34 rows of 18 tiles.
How many total tiles does he need?
lets start off by saying that each row has 18 tiles
and there are supposed to be 34 rows
so you can multiply the number of tiles in each row (18) by the number of rows (34)
34 x 18 = 612
the handyman needs a total of 612 tiles to cover the floor.

Y=13
(when you have fractions like the one in this problem, you get rid of them by multiplying both sides by the denominator.)
Answer:
1/2 X + X -15 + 1/2 X + 100 + X -25 = 540
1/2x + x + 1/2x + x -15 + 100 -25 = 540
3 x + 60 = 540
3x + 60 - 60 = 540 - 60
3/3x = 480/3
x = 160
Step-by-step explanation:
1/2 X + X -15 + 1/2 X + 100 + X -25 = 540
1/2x + x + 1/2x + x -15 + 100 -25 = 540
3 x + 60 = 540
3x + 60 - 60 = 540 - 60
3/3x = 480/3
x = 160
