Answer:
The value of 7w - 8 is -22
Step-by-step explanation:
Let us solve the question
∵ -4w - 5 = 3
→ Move -5 from the left side to the right side by adding both sides by 5
∴ -4w - 5 + 5 = 3 + 5
∴ -4w = 8
→ Divide both sides by -4
∵
= 
∴ w = -2
→ Now let us find the value of the given expression
∵ The given expression is 7w - 8
→ Substitute w by -2 to gets its value
∴ 7w - 8 = 7(-2) - 8
∴ 7w - 8 = -14 - 8
∴ 7w - 8 = -22
∴ The value of 7w - 8 is -22
Answer:
y=179x
Y=105x+2046
Step-by-step explanation:
The value of x from the figure is 30 degrees
<h3>Parallel lines</h3>
Parallel lines are lines that have the same slope and have 0 degrees as the angle between them.
The sum of angle 5 and angle 6 are supplementary. Hence;
m<5 + m<6 = 180
3x - 33 + 123 = 180
3x + 90 = 180
3x = 180 - 90
3x = 90
Divide both sides by 3
3x/3 = 90/3
x = 30
Hence the value of x from the figure is 30 degrees
