Help solving this math homework

Mathematics

8.

33 = 2y + 1 + y - 1

Add the 1 and -1

Add the y and 2y

33 = 3y

11 = y

9, AQ = 2y + 1

2(11) + 1

22 + 1

23

AQ = 23

10, QX = y - 1

QX = 11 - 1

10

QX = 10

11. 62 = 3x - 4 + 3x - 4

Add -4 and -4

Then add 3x + 3x

62 = 6x

Divide 62 by 6x

x = 11 2/3

AB = 3x - 4

3 (11 2/3) - 4

3 * 11 2/3 = 35

35 - 4 = 31

AB = 31

Both sides are equal, so BC also equals 31

12. 206 = 3x - 4  + 3x - 4

206 = 6x

x = 34 1/3

AB = 3x - 4

AB = 3(34 1/3) - 4

AB = 103

Because AB and BC are the same, BC also equals 103.

Why are inverse relationships between operations used to solve two step inequalities?
zhenek [66]

Answer:

The goal in solving an equation is to get the variable by itself on one side of the equation and a number on the other side of the equation. To isolate the variable, we must reverse the operations acting on the variable. We do this by performing the inverse of each operation on both sides of the equation.

Reverse addition and subtraction (by subtracting and adding) outside parentheses. Reverse multiplication and division (by dividing and multiplying) outside parentheses. When multiplying or dividing by a negative number, flip the inequality sign. It does not matter if the number being divided is positive or negative

It's necessary to apply inverse operations on both sides of the equals signs so that you can solve for the variable and balance the equation.

Multi-step inequalities are solved using the same processes that work for solving equations with one exception. When you multiply or divide both sides of an inequality by a negative number, you must reverse the inequality symbol. (Much like when you divide by a negative number, the sign of the inequality must flip! Here's why: When you multiply both sides by a negative value you make the side that is greater have a "bigger" negative number, which actually means it is now less than the other side!)

Answer:

  x = 22.5°

Step-by-step explanation:

Angle BED ≅ angle EBC = 6x, so angle BEA = 4x. The angles FEB and BEA form a linear pair, so we have ...

  4x +4x = 180°

  x = 22.5° . . . . . . divide by 8

_____

BED and EBC are "alternate interior angles" with respect to transversal BE crossing parallel lines DE and AC.
