Answer:
I think the table is linear. The total amount after one year is 248 ants.
Step-by-step explanation:
For this case, the first thing we must do is define variables:
x: Jane's age
y: Helen's age
By writing the system of equations we have:
y = x + 8
y-20 = 3 (x-20)
Solving the system we have:
x = 24
y = 32
Answer:
Jane is 24 years old
Helen is 32 years old
the equation for Jane would look like:
x + 8 = 3 (x-20) + 20
Answer:
2x=0
x=0
Step-by-step explanation:
11-3x=5(2-x)+1
We first distribute the 5 to 2 and -x:
11-3x=10-5x+1
Combine like terms (combine all variables and then combine all constants)
-3x+5x=10+1-11
2x=0
x=0
Answer:
Mistake -2(x+5)=-2x+10, -2(x+5)=-2x-10
Step-by-step explanation:
7(x-10)-2(x+5)=4x-7+6x-3
7x-70-2x-10=10x-10
5x-80=10x-10
-80+10=10x-5x
-70=5x
-70/5=x
-14=x
