Question 2:
The answer is 21
The two angles are vertically opposite, which makes them equal and also means we can make an equation:
4x - 4 = 3x + 17
- 3x
x - 4 = 14
+ 4
x = 21
Question 3:
The answer is 23
Again, the angles are vertically opposite, so we can make them equal each other:
5x - 53 = 3x - 7
- 3x
2x - 53 = -7
+ 53
2x = 46
÷ 2
x = 23
I hope this helps!
I think it’s D. 102 but it may not be.
Answer:
Option (D)
Step-by-step explanation:
Kevin delivers newspaper in his town and earns an amount represented by a linear equation,
y = 30x + 18
Here, y = total earnings
x = number of houses he delivers the newspaper
If he doesn't deliver any newspaper on a certain day, (x = 0)
Then total earnings, y = 30(0) + 18
y = 18 cents
Therefore, a certain amount of 18 cents will be paid even if he doesn't deliver any newspaper on a certain day.
Option (D) is the correct option.
X=70... do u need an explanation?
Answer:
y=-2x+7
Step-by-step explanation:
The formula for this is y=mx+b
the m is the slope, and the b is the intercept, just plug them both in to make it work.
