cross multiply
1 * x = 13.5 * 5
x = 67.5
3 x 10 to the sixth power
3 x 10 to the fifth power
7 x 10 to the fourth power
6 x 10 to the first power
I might be wrong though. If so, sorry!

Answer:
y=29.
Step-by-step explanation:
To find the value of y:
y+(y+1)+(y+2)=90
Firstly, collect like terms
3y+3=90
3y=90-3
3y=87
Divide both sides by 3
y=29.

1. 8 = 8 => refrexive
2. If x = y, then y = x => symmetric
3. If x = y and y = 7, then x = 7 => transitive
4. 6 + 2 = 2 + 6 => commutative - addition
5. 5 ∙ 2 = 2 ∙ 5 => commutative - multiplication
6. 10 + (3 + 2) = (10 + 3) + 2 => associative - addition
7. 6(3 ∙ 5) = (6 ∙ 3)5 => associative - multiplication
8. 4(8 + 1) = 4 ∙ 8 + 4 ∙ 1 => distributive
9. 6 + 0 = 6 => identity - addition
10. 8 ∙ 1 = 8 => identity - multiplication
11. 1/2 ∙ 2 = 1 => multiplicative inverse
12. 5 ∙ 0 = 0 => property of zero
