Answer:
yes
Step-by-step explanation:
2(x-y) you distribute the 2 to whats inside the parenthesis
2x-2y
Remember y ou can do anything to an equation as long as you do it to both sides
get 1x by itself
8x-12=4x+24
add 12 to both sides
8x=4x+36
minus 4x from both sides
4x=36
divide both sides by 4
x=9
Answer:
Riding is independent variable and cost is dependent....
Step-by-step explanation:
According to the given statement Jewels has $6.75 to ride the ferry around Connecticut. It will cost her $0.45 every time she rides.
It means that if she rides a ferry, she pays
If she does not ride the ferry she won't pay
This shows that the paying depends on riding.
Thus riding is independent variable and cost is dependent....
Answer:
The system has one solution.
Step-by-step explanation:
We have two equations:
y = -2x - 4
y = 3x + 3
Equalling them:
y = y
-2x - 4 = 3x + 3
5x = -7
And
Replacing in the other equation we should get the same result.
So the system has one solution.
There are 12 inches in one foot. 120 x 12 = 1,440 inches. The correct ratio to be placed is the 5th one (aka 12 inches over 1 foot).
