4x - 50)° and (x + 60)° are a pair of supplementary angles. x = ________ ⁰ . (Write only the value of x) 4x - 50)° and (x + 60)° are a pair of supplementary angles. x = ________ ⁰ . (Write only the value of x)
Answer:
(4x-50)°+(x+60°)=180°
5x+10=180°
5x=180-10
5x=170
x=170/5
x=34
Answer:
x = 34
Step-by-step explanation:
4x - 50 + x + 60 = 180
Transpose all constant to the right side
4x - 50 + x + 60 = 180
+ 50 - 60 + 50 - 60
4x + x = 170
Add like terms
5x = 170
Divide 5x with its constant (5). Also, divide 170 with the constant.
5x = 170
x = 34

Find the greatest common factor of 14 and 55.
HELP?
Answer:
1
Step-by-step explanation:
Factors of 14.
1, 2, 7, 14
Factors of 55.
1, 5, 11, 55
The GCF is the greatest factor they both have in common. In this case it’s 1.
Best of Luck!
Hello.
To find the Greatest Common Factor of two numbers, you have to break it down by finding its prime factors, then multiply the greatest number both numbers have in common.
The Factors of 14 are: 14, 7, and 1.
The Factors of 55 are: 55, 11, and 1.
The greatest number both numbers have in common are 1.
1 x 1 = 1
Therefore, the Greatest Common Factor of 14 and 55 is 1.

explain how you solve this: -7 = -1 + x/3
Answer:
-18 =x
Step-by-step explanation:
-7 = -1 + x/3
Add 1 to each side
-7+1 = -1+1 + x/3
-6 = x/3
Multiply each side by 3
-6*3 = x/3*3
-18 =x

Roman can type 3 pages in 60 minutes. How many more pages can Roman type in 90 minutes than in 60 minutes? Assume the relationship is proportional and he types at a constant rate.
Answer:
Roman can type 1.5 more pages in 90 minutes than 60 minutes.
Step-by-step explanation
In 60 Roman can type 3 pages. Divide those numbers in half to find out how many pages he can type in 30 minutes. Add 30 minutes to 60 minutes and 3 pages to 4.5 to get 90 minutes.
Roman can write = 4.5 - 3 = 1.5 = 1 and a [tex]$\frac{1}{2}[/tex] page more in 90 minutes than in 60 minutes.
We have Roman who can type 3 pages in 60 minutes.
We have to find out how many more pages can Roman type in 90 minutes than in 60 minutes.
If you solve 5 questions of mathematics in 1 hour, then how many questions will you solve in 10 hours.The number of questions you will solve will be = 5 x 10 = 50 questions.
According to the question, we have -
Number of pages typed by Roman in 60 minutes = 3
Therefore -
In 60 minutes → 3 Pages.
In 1 minute → 3/60 Pages.
In 90 minutes → [tex]\frac{3}{60} \times 90[/tex] = 4.5 pages = 4 and a [tex]$\frac{1}{2}[/tex] page.
Therefore, Roman can write = 4.5 - 3 = 1.5 = 1 and a [tex]$\frac{1}{2}[/tex] page more in 90 minutes than in 60 minutes.
Hence, Roman can write 1 and a [tex]$\frac{1}{2}[/tex] page more in 90 minutes than in 60 minutes.
