Answer:
x=
−4y+32
9
Step-by-step explanation:
Let's solve for x.
y=
−9
4
x+8
Step 1: Flip the equation.
−9
4
x+8=y
Step 2: Add -8 to both sides.
−9
4
x+8+−8=y+−8
−9
4
x=y−8
Step 3: Divide both sides by (-9)/4.
−9
4
x
−9
4
=
y−8
−9
4
x=
−4y+32
9
I think this is the right answer.
Answer:
- North Middle School = 10 students
- Central Middle School = 6 students
- South Middle School = 4 students
Step-by-step explanation:
First calculate the total number of students in all the schools:
= 618 + 378 + 204
= 1,200 students
Use this number to calculate the proportion of the total population that a school so that this can then be used to determine the proportion of the 20 delegates they should sent.
North Middle school:
= 618/1,200 * 20
= 10 students
Central Middle School:
= 378 / 1,200 * 20
= 6 students
South Middle School:
= 204/1,200 * 20
= 4 students
Answer:
46%
Step-by-step explanation:
For percents, we want to make the number out of 100. 23/50 is the same as 46/100. From fraction knowledge, 46/100 is 46%.
Answer:
first two is 300, then it is Car A's speed is 50mph and b is 40mph and for the other two it is probably faster and steeper
Step-by-step explanation:
you look at the graph. you see 6 miles and look up along the 6 mile line to see where it intersects the red line. once you find that spot you go left along that line to find the answer. same with the other and it both ends up at 300
for the next two find the slope, which is 40 and 50
and for the next two there are multiple answers but i t is probably faster and steeper
