Answer: 9-3x
Step-by-step explanation:
You add like terms
don't look at the 3x for now
positive 7 + positive 2 = 9
there is a negative sign next to 3x
9 goes first so
9 - 3x
Answer:
number of cans Raina will be needed in court floor is 14 cans
Step-by-step explanation:
CHECK THE COMPLETE QUESTION BELOW;
Raina is staining the wooden floor of a court. The court is in the shape of a rectangle. Its length is 46 feet and its width is 35 feet. Suppose each can of wood stain covers 115 square feet. How many cans will she need to cover the court?
CALCULATION;
Given:
length of the rectangular shape =46 feet
width of the the rectangular shape = 35 feet.
The floor of the court room is having a rectangular shape, then we need to calculate the surface Area of the rectangular shape first in order to know the number of cans that Raina will be needed
Surface Area= Length × Width
= 46feet × 35 feet
=1610 square ft
Then to get the number of cans , we need to divide the surface Area by each can of wood stain covers which is 115 square feet,
number of cans Raina will be needed in court = 1610 square ft / 115 square ft = 14
number of cans Raina will be needed in court floor is 14cans
I would subtract the 2nd from the first one
so -4x - -2x = -2x
4y - 4y = 0
-20 - -2 = -18
-2x = -18
now I would divide that by -2 to get the value for x
so no we have x = 9
now you just have to substitute that into one of the equations and simplify to get y
-2 X 9 + 4y = -2
-18 + 4y = -2
4y =16
y = 4
