1/7 + x = 2/3x
1/7 = 2/3x-x
1/7 = 2/3x - 1x
1/7 = -1/3x
-3/7 = x
Answer:
(-1,8)
(4,-27)
Step-by-step explanation:
y+7x=1
Let x = -1 and find y
y+7(-1)=1
y -7 =1
Add 7 to each side
y-7+7 = 1+7
y = 8
(-1,8)
Let x = 4 and find y
y+7(4)=1
y +28 =1
Subtract 28 from each side
y+28-28 = 1-28
y = -27
(4,-27)
You divide 44 by 9 and get 4.89 so u can round up either to the 8 or the 4 is you could get either 4.9 or 5
Answer:
30 leaps
Step-by-step explanation:
Equation of rabbit:
y=7x+150
Equation of kangaroo:
y=12x
To solve the system of equations, use substitution
12x=7x+150
5x=150
x=30
