You can solve this with proportion
1) For 2h
9/2 mile : 3/4h = x mile : 2h => (3/4)x=(9/2)*2 => (3/4)x=9 => x=9*(4/3)= 12miles
For 3h => (3/4)x=(9/2)*3 When we divide equation with 3 we get
x/4=9/2 => x=(9/2)*4=18 miles
2) 2 combine : 320 acres = 7 combines : x acres +: 2x= 320*7 =>
x= (320*7)/2 = 160 * 7 = 1120 acres
Good luck!!!
. The student's conclusion is incorrect because the solution to the system of equations 4x + 2y = 32 and 5x + 2y = 36 is (4, 8).
B is right option
4x + 2y = 32
5x + 2y = 36 subtracting
-x=-4
x=4
4(4)+2y=32
16+2y=32
2y=16
y=8
hope this helps
101 is your answer.
20 x 5 = 100 ,
100 + 1 = 101
Answer:
Sale tax rate = 7.5%
Step-by-step explanation:
The book cost $12.95
If you take 12.95 x 0.075 = 0.97125
Round the answerto the hundredth (0.97)
Add the tax, 12.95 + 0.97 = 13.92
Answer:
point-slope form:
y - 10 = -4(x - -2)
y - 10 = -4(x + 2)
---
slope-intercept form:
y - 10 = -4x - 8
y = -4x - 8 + 10
y = -4x + 2
