Answer:
x=5
Step-by-step explanation:
since two sides are congruent, the two unknown angles are congruent.
All triangle angles total 180 degrees.
so:
180-88=92
92/2=46
9x+1=46
9x=45
x=5
3x=x+40
Subtract x from both sides
2x=40
Divide both sides by 2nto get x by itself
x=2
Plug 2 in for x
m∠4 = (3x)
m∠4 = 3(2)
Solve
m∠4 = 6
Answer:
Two boxes will cost
The cost of one tile is approximately 
Step-by-step explanation:
Note that 1 ft = 12 in, then

The area of the floor is

Now

then
144 sq. in - 1 tile,
9540 sq. in - x tiles.
Mathematically,

tiles is needed to cover the floor (67 full tiles).
Each box of tiles contains 45 tiles, so Cristina has to buy 2 boxes. These two boxes will cost
The cost of one tile is approximately 
Answer:
there you go . Good luck plz mark me brainliest .
I came up with 7+5(x-1)
7 is a fixed one time cost.
5(x-1). x-1 because you have already charged $7 for the first hour.
Checking to make sure it is correct
so if a person stays 1 hour
7+5(1-1)
7+5(0) = 7
This answer makes sense because they get charged $7 the first hour
so say they stay 3 hours
7+5(3-1)
7+5(2) = 17
This answer makes sense because they get charges $7 for the first hour and $5 for the other 2. so 7+5+5=17.
we can see that the function works
