Answer:
y=10
Step-by-step explanation:
2y+3+9y-7+7y+4=180
18y=180
y=10
The solution to the statement 4 + (-4) is correctly given by the third number line.
- The solution given by plot 1 is : (-4) + (-4) as both arrows points 4 units to the left.
- The solution given by plot 2 is : ( 4 + 4) as both arrows points 4 units to the right.
- The solution given by plot 3 is (4) + (-4) as one arrow points 4 units to the left and the other points 4 units to the right.
- The solution given by the plot 4 is (-4 + 8) as one arrow points 4 units to the left and the other points 8 units to the right.
Therefore, the Number line which shows the solution 4 + (-4) is the third number line.

Answer:
F (4h>18)
How To Do It:
She's walking at a rate of 4 miles per hour. Which means that you would be multiplying 4 by the amount of hours Liang walks(4h). The next part of the inequality is the sign and the other value. To get this from the equation we see that it says she must walk at least 18 miles. Meaning that the 4h will always be greater than the 18 that is on the other side.
Answer:
x = 52/3
Step-by-step explanation:
3x / 7x = (3x+7) / (3x+7+5x-8)
3/7 = (3x+7)/(8x - 1)
Cross multiply
7(3x+7)=3(8x-1)
21x + 49 = 24x - 3
-3x = -52
x = 52/3
Answer:
B (4, 2+3)
Step-by-step explanation:
To do this you fill in x with 4 so the equation becomes y = (4)2 - 3
You then solve to y = 8 - 3
then 8 - 3 is 5.
Making the coordinates (4, 5) and in this case with the answers (4, 2+3)
