I would get $19 back if I gave the clerk $40

An equation is an expression used to show the relationship between two or more variables and numbers.

Total money spent on book and CD = $12 + $9 = $21

The money gotten back = $40 - $21 = $19

I would get $19 back if I gave the clerk $40

Mai biked 6\frac{3}{4} miles today, and Noah biked 4\frac{1}{2} miles.
Alinara [238K]

It was 1.5 times the length of Noah's bike ride as Mai’s bike ride.

The problem we dealing with is related to mixed numbers which are referred to as mixed numbers and could be the whole number, and a proper division spoke together. It for the most part speaks to a number between any two whole numbers.

Since we are providing mai's rate which is  6 3/4  miles and Noah's  rate of 4 1/2 miles, So in  order to find the time the length of Noah's ride is compared to Mal's, we just need to divide the given rates by each other

=> 6 3/4 divided by 4 1/2,  

=> 27/4 divided by 9/2, (The result is an improper fractions)

=> 27/4 X 2/9

=>3/2

=> 1.5

I need help with this geometry question!
Ksenya-84 [330]
Hello there! So, this is a quadrilateral and quadrilaterals equal 360 degrees. Let’s combine like terms to start off. 39x + 9 = 360. First, let’s subtract 9 from both sides to get 39x = 351. Next, divide each side y 39 to isolate the “x”. When you do that, x = 9. Now, let’s plug in the values for each, when you do, here are the final answers.

x = 9
E = 75 degrees
F = 91 degrees
G = 89 degrees
H = 105 degrees

Those are all of the angle measurements, but it wants the measurement of angle H. Therefore, that angle measurement is 105 degrees.
