What is 791=1/2h (26.5+30)

Answers

Answer 1

Answer: Following the order of PEMDAS, start with what's inside of the parenthesis, adding 26.5 with 30 ---> 791 = 1/2h(56.5)
You need to get h on one side of the equation by itself. To do this, divide the whole equation by .5 (which is the same as 1/2), canceling out the 1/2 on one side of the equation. 791/.5 = 1/2h(56.5)/.5 ----> 1582 = h(56.5)
Next, divide the entire equation again by 56.5. 1582/56.5 = h(56.5)/56.5
---> 28 = h
Your final answer is h = 28. To check this, plug 28 into the equation where the value h is.

The value of 'm' for the given equation as per linear equation will be 8.

What is a linear equation?

Linear equation is an equation where the variable has the highest degree of 1.

Given, twice a number m minus three equals the sum of m and five.

Therefore, the linear equation will be:

2m - 3 = m + 5

⇒ 2m - m = 5 + 3

⇒ m = 8.

The value of 'm' is 8.

Evaluate the expression. 42 + 5 • 32 – 42 ÷ 23

Answers

42 + 5 * 32 - 42 ÷ 23

I am going to use the PEMDAS order. Parenthesis, Exponents, Multiply, Divide, Add, Subtract

Multiply ⇒ 5 * 32 = 160
42 + 160 - 42 ÷ 23

Divide ⇒ - 42 / 23 = -1.83
42 + 160 - 1.83

Add ⇒ 42 + 160 = 202
202 - 1.83

Subtract ⇒ 202 - 1.83 = 200.17

42 + 5 * 32 - 42 ÷ 23 = 200.17

Which is smaller, half of 36 or one seventh of 42

Answers

One seventh of 42 because it would be 6, and one half of 36 would be 18

half of 36 is 18 and 1/7 of 42 is 6 so 6 is the smallest number.
