Answer:
The first law of motion
Step-by-step explanation:
1 it grows 18 inches every 3 months
there are 12 months in 1 year
12 dived by 3 = 4 so there are 4 times it will grow 18 inches
18 * 4 = 72 inches, amount it grows in 1 year
Answer is D
2. it grows 9 inches every 2 months
12/2 = 6 times a year it will grow
9 *6 = 54 inches total for 1 year
Answer is C
Let’s arrange the fist equation
x+y=12
2x+3y=29
Multiply equation 1 by 2
So it will be
2x+2y=24
Subtract eq 1 from eq 2
2x+3y=29
2x+2y=24
—————-
Y =5
Put value of y in eq 1
2x+2y=24
2x +10= 24
2x= 24-10
2x= 14
x=14/2
x=7
S.S= (7,5)
Answer:
2.96
Explanation:
37/x=100/8
(37/x)*x=(100/8)*x - we multiply both sides of the equation by x
37=12.5*x - we divide both sides of the equation by (12.5) to get x
37/12.5=x
2.96=x
x=2.96
Answer:
-2
Step-by-step explanation:
4x:3=6:5.
4x/3=6/5
4x × 5=6×3
20 X=18
X=18-20
X=-2
