Answer:
x = 5
Step-by-step explanation:
4x - 5x + 1 = -4
4x - 5x = -4-1
-x = -5
x = 5

Answer:
602.42 million
Step-by-step explanation:
I know the answer is 602.42 million because I used addition and subtraction.
First, I knew there was 5.66x 107 million students. So, I multiplied 5.66 and 107, and I got 605.62 million. I knew there were 3.2 million teachers in the US. Next, I subtracted 3.2 million from 605.62 million.
605.62-3.2=602.42
So, there are 602.42 million more students than teachers in the United States.
Answer:
Week 4
Step-by-step explanation:
Ben has $250 in the beginning. He saves $150 per week.
y = 150x + 250
Tim has $1,650 in the beginning. He spends $200 per week.
y = 1650 - 200x
We are trying to find which x-value produces the same y-value for both equations. You can do this by setting both equations equal to each other.
150x + 250 = 1650 - 200x
(150x + 250) + 200x = (1650 - 200x) + 200x
350x + 250 = 1650
(350x + 250) - 250 = (1650) - 250
350x = 1400
(350x)/350 = (1400)/350
x = 4
By week 4, they will have the same amount of money.
Answer:
See explanation
Step-by-step explanation:
In the figure below, segment CD is parallel to segment EF, DE is a transversal, then angles DIH and HGI are congruent as alternate interior angles when two parallel lines are cut by a transversal.
Consider triangles DIH and EGH. In these triangles,
as alternate interior angles;
as vertical angles;
because point H bisects segment DE (given).
Thus,
by AAS postulate
Answer:
32
Step-by-step explanation:
The length of segment AB is the average of XY and WZ.
(22 + x)/2 = 27
22 + x = 54
x = 32
