Matt and Ming are selling fruit for a school fundraiser. Customers can buy boxes of oranges and boxes of apples. Matt sold 3 box
ANEK [815]

Answer:

The Answer is that one box of Oranges costs $7.13 and one box of Apples costs $12.99.

Step-by-step explanation:

Let o = oranges and a = apples

Equation 1:

3o + 14a = 203

Solve for o:

3o = 203 - 14a

o = 203/3 - 14/3a

o = 67.66 - 4.66a

Equation 2:

11o + 11a = 220

Substitute:

11(67.66 - 4.66a) + 11a = 220

744.26 - 51.26a + 11a = 220

-40.26a = 220 - 744.26

-40.36a = -524.26

a = -524.26/-40.36 = $12.99 for a box of Apples

Solve for oranges, o:

o = 67.66 - 4.66a

o = 67.66 - 4.66(12.99)

o = 67.66 - 60.53 = $7.13 for a box of Oranges

Hope this helps!! Have an Awesome day!!! :-)

Oliver is thinking of a number. He multiplies it by 5, subtracts 26, and then divides by 6. He then multiplies his original numb
Free_Kalibri [48]

Answer:

-2

Step-by-step explanation:

Let Oliver's number be x.

He multiplies it by 5:

x * 5 = 5x

He then subtracts 26:

5x - 26

Then, he divides by 6:

\frac{5x - 26}{6}  

He then multiplies his original number by 3, and gets the same answer.

This implies that:

\frac{5x - 26}{6} = 3x

Let us simplify this:

\frac{5x - 26}{6} = 3x\\\\5x - 26 = 3x * 6\\\\5x - 26 = 18x

Collecting like terms:

5x - 18x = 26\\\\-13x = 26\\\\=> x = \frac{26}{-13}\\\\x = -2

Oliver's number is -2.
