Help!! Please I’m stuck give [10pts]
pishuonlain [190]

Answer:

x = 18

Step-by-step explanation:

To solve this problem, we can use the exterior angle theorem, which means the measure of an exterior angle is the sum of its remote interior angles. In this case, this would mean:

x + 72 = 5x

Since this gives us an equation, we can just solve for x:

x + 72 = 5x

72 = 4x

x = 18

Aisha bought 15 apples and oranges for $9. 0. Each orange costs $0. 50, and each apple costs $0. 65. Let x represent the number
zhannawk [14.2K]

Answer:

x + y = 15

0.5x + 0.65y = 9

Step-by-step explanation:

x = number of oranges

y = number of apples

total of apples and oranges is 15 so x + y = 15

total cost of apples and oranges is $9 so 0.5x + 0.65y = 9

Calculation

y = 15 - x

0.5x + 0.65(15-x) = 9

0.5x - 0.65x + 9.75 = 9

-0.15x = - 0.75

x = 5

y = 15 - x = 15 - 5 = 10

Alice planted some corn in the back yard and measures it’s height regularly. The last time she checked, the stalks were 60 inche
sdas [7]

Answer:

The percent of increase in height of the stalks is 20%.

Step-by-step explanation:

The general formula for a percent increase is as follows:  (Original Amount - New Amount/Original Amount) x 100.  The original height of the stalks was 60 inches tall.  The new height of the stalks is 72 inches.  In the numerator of our fraction, we take 72-60 to get 12.  Our denominator is the original amount, or 60.  This gives us an overall fraction of 12/60, which when we divide gives us 0.2.  Once we multiply our decimal by 100, we get an overall percent increase of 20%.
