Answer: It is 7
Step-by-step explanation:
Answer:
The wall is 90 meters wide.
Step-by-step explanation:
1. set up and solve a proportion to find the value of w like this:
1cm=6cm
15m=wm
2. cancel out the like units on both sides of the equation
1=6
15=w
3. Equate the cross products, and then solve for w:
1*w=15*6
w=90 The actual width of the wall is 90 meters.
5 Bars of soap for $4.00 Why? Because you if you buy two it cost $8.00 or buy three pack and you'll get 15 for $12.00
Y=3x
x-2
The correct answer is y=6
To see how they are related, let us solve the two equations.
FIRST EQUATION
SECOND EQUATION
Hence the solutions to the two equations are ADDITIVE INVERSE of each other.
