How do you solve this equation?

Answers

Answer 1

Answer: Thenswer is p is greater than or equal to 4. which, you already wrote.

steps:
1. subtract 140 from both sides. now you have: 15p (is greater than or equal to) 60.

2. divide both sides by 15.

3. simplify. now, the answer is p (is greater than or equal to) 4.

Answer 2

Answer: The inequation is:
140+15x≥200

15x≥200-140
15x≥60
x≥60/15
x≥4

Thirty four divided by x is the same as 17

Answers

the answer is x = 2

34/x = 17

multiply both sides by x

34/x x = 17x

multply 34/x

and it gives you 34 = 17x

then switch sides 17x = 34

divide both sides by 17

17x/17 34/17

and that gives you x = 2

What is the greatest common factor of 45 and 72 please explain !!!!

Answers

The greatest common factor (GCF) of 45 and 72 is: 9

Factors of 45: 1, 3, 5, 9, 15, 45
Factors of 72: 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36

The common factors between the two numbers are 1, 3, and 9, but since 9 is the highest, it is considered the greatest common factor.

The greatest common factor of 45 and 72 is 9.

The given numbers are

45 and 72

We know that,

The greatest common factor (GCF) is the biggest number that is a factor of two or more numbers.

The greatest number (factor) divides them, yielding a Natural number. Once all of the number's variables have been identified, there are a handful that are shared by both.

The greatest common factor is the largest number found among the common factors. The GCF is often referred to as the HCF (Highest Common Factor).

Now factorize 45

45 = 3x3x5

Now factorize 72

72 = 2x2x2x3x3

Now the common factors are:

3x3

= 9

Thus the GCF ⇒ 9
