Answer:
10
Step-by-step explanation:
Construct the equation
Let S=Sarah J=Jane
S=J+6
2J+3S = 68
Using substitution you can get
3(J+6)+2J = 68
5J + 18 = 68
5J = 50
J= 10
Answer:
Although this isn't a question i tried to explain...
Step-by-step explanation:
An equation is just a problem with an = sign .
to solve this you must:
1) get the variable by itself
2) solve for the variable
EXAMPLE:
3x – 2 = 16
1) add 2 to both sides get 3x by its self on one side (-2 and 2 cross each other out.)
3x = 18
2) divide 3 into 18
18 ÷ 3 = 6
x = 6
earnings * 20 percent = 17
earnings * .2 = 17
divide by .2 on each side
earnings = 17/.2
earnings = $85.00
A. 8 * 3 = 24
b. -7 * 5 = -35
c. -6 * -9 = 54
d. 8 / -2 = -4
e. -24 / -3 = 8
f. -36 / 6 = -6
Answer:
Your answer would be C
Step-by-step explanation:
18 inches was the height of the baby when they were born since it isn't y which would be the current height of the baby now in months that tells me months have passed which includes x is the age of the baby in months.
