Answer:
She needs $30.
Step-by-step explanation:
170 minus 140 is 30.
A)
a+b=180 and a=2(b-30) using this in the first equation gives you:
2(b-30)+b=180
2b-60+b=180
3b-60=180
3b=240
b=80 so a=100
Andre's score was 100 and Brandon's score was 80.
b)
100x-200>50x-75 subtract 50x from both sides
50x-200>-75 add 200 to both sides
50x>125 divide both sides by 50
x>2.5
Answer:
x = - 9 (negative 9)
Step-by-step explanation:
The x intercept is where y = 0. When y = 0, the point is on the x axis.
So use the equation and replace y with 0.
-2x + 1/2y = 18
-2x + 1/2(0) = 18
-2x + 0 = 18
-2x = 18
x = - 9
Check you answer by putting your answer for x into the equation. See if it does make y = 0
-2x + 1/2y = 18
-2(- 9) + 1/2y = 18
18 + 1/2y = 18
1/2y = 0 so y must also equal 0
