Just use the orders of operation, or PEMDAS

Parenthesis, Exponents, Multiplication, Division, Addition, Subtraction

63 + (15 - 6) * 14 + 2

Parenthesis first!

63 + 9 * 14 + 2

No exponents, let’s multiply!

63 + 126 + 2

No division or subtraction, let’s add the rest

Can you plz tell me how to work it out plz I need it but today

First we gather all the information we have about the amount of miles that Carolyn runs:
Monday, Wednesday, Friday: 4 1/2 miles
Tuesday, Saturday: 2 3/4 miles
And the question is the amount of miles that she runs in 4 weeks.
So lets begin by calculating the amount of miles she runs in one week, then we just multiply by 4 and we'll have the final answer.
So, we have to add 4 1/2 three times (Monday, Wed, Friday), and 2 3/4 two times (Tuesday, Sat):
1 week Miles = 4 1/2 + 4 1/2 + 4 1/2 + 2 3/4 + 2 3/4
lets add the whole parts and the fraction parts apart:
1 week Miles = (4 + 4 + 4 + 2 + 2) + (1/2 + 1/2 + 1/2 + 3/4 + 3/4)
1 week <span>Miles = (16) + (3/2 + 6/4)
</span>we can reduce the last fraction:
1 week <span>Miles = (16) + (3/2 + 3/2)
</span>1 week <span>Miles = (16) + (6/2)
</span>1 week <span>Miles = (16) + (3)
</span>1 week <span>Miles = 19
</span>therefore Carolyn runs 19 miles each week, so for 4 weeks we have to add 19 four times or multiply it by 4, is the same:
4 weeks <span>Miles = 4*19
</span>4 weeks <span>Miles = 76
hence Carolyn runs 76 miles in 4 weeks.</span>

The diameter of Joe's large pizza is 19 inches. Approximately how many inches are there in the circumference of the large pizza?
Burka [1]

Answer:

There are 59.66 inches in the circumference of the large pizza.

Step-by-step explanation:

It is given that:

Diameter of Joe's large pizza = 19 inches

Diameter = 2r

2r = 19

Circumference of large pizza = 2πr = 2r * π

Circumference of large pizza = 19*3.14

Circumference = 59.66 inches

Therefore,

There are 59.66 inches in the circumference of the large pizza.
