Answer:

26) 1/2 b×h

= 1/2(8×9)

=1/2(72)

=36

27)1/2b×h

=1/2(12×15)

=1/2(180)

=90

28)a÷b×2

=(60÷8)×2

=15

29)1/2b×h

=1/2(16×1/2)

=1/2(8)

30)1/2b×h

=1/2(18×12)

=1/2(216)

=108

Answer:

a. (5x+75)°

b. x = 21

c. X° = 21° and (4x+75)°= 159°

Step-by-step explanation:

A. Combine like integers.

B. (5x+75)°=180° Because they are suplementary angles.

5x°= 105°

5x ÷5 = 105 ÷ 5

x = 21

C. (4x + 75)°

4(21) + 75

84 + 75 = 159°

A teacher asked his students to solve the equation w-15=22. One student incorrectly said that the solution is 7. What is the cor

jonny [76]

Answer:

$w= 37$

Step-by-step explanation:

The student used the wrong property of equality.

When you undo a number to get a letter by itself, you should do the opposite operation of the number said. The student subtracted 15 from 22 instead of adding 15 to 22.

Use the addition property of equality to isolate w.

$w(-15+15)=22+15\\w=37$
