Answer:

x = 6 degrees

Step-by-step explanation:

A straight line is 180 degrees and we can make out three angles the form it, this means the three of them add to 180 using the straight angle theorem:

5x + x + 54 + 90 = 180

6x + 144 = 180

6x = 36

x = 6

Answer:

Simplifying

5x + x = 54

Combine like terms: 5x + x = 6x

6x = 54

Solving

6x = 54

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Divide each side by '6'.

x = 9

Simplifying

x = 9

jeyben [28]

Answer:

Alex can line eight 1-meter wide with the paper.

Step-by-step explanation:

- Alex has five rolls of shelf paper that is 800cm.

- She wants to use the paper to line the 1-meter wide shelves in her pantry.

- We want to determine how many 1-meter wide she can line with the paper.

- First, we know that

100cm = 1m

- we need to determine how many meters are in 800cm.

100cm = 1m

800cm = xm

100x = 800

x = 800/100

= 8

Therefore, 800cm is equivalent to 8m

Alex can line eight 1-meter wide with the paper.

Jim drove 152 miles in 4 hours. if he can keep the same pace, how long will it take him to drive 760 miles?
alexandr402 [8]
First we need to find the rate which is the total amount driven divided by the total time.

152/4 = 38 miles per hour.

No we take the total driven miles given and divide it by the rate to find how long it would take!
760/38 = 20 hours!
Hope this helps :D
