Answer:

X = 27

you multiply both sides and get 3x-27=x+27

then you move the terms and you get 3x-x=27+27 then calculate and get 2x=54 then divide and you get x==27

How tall would one million pennies be in centimeters.And how do you know

Vikki [24]

One US-penny is 19 mm in diameter.

One British-penny is 20.3 in diameter.

We can make an accurate measurement of the diameters, or research on the internet.

1 milion US_pennies are

1,000,000*19 mm = 19,000,000 mm = 1,900,000 cm tall, since 1cm=10mm

1 milion British_pennies are

1,000,000*20.3 mm = 20,300,000 mm = 2,030,000 cm tall, since 1cm=10mm

Polly’s favorite cereal has 270 calories. The nutrition label on the box states that 56 of the calories come from fat. How many

Crazy boy [7]

I'm going to assume that you mean 56% of the calories come from fat. So, we would have to find out 56% of 270 which is 151.2, so now we know that 151.2 calories in the cereal come from fat!
