Jesean buys a pizza for 20$ and 10 drinks. The drinks Cost the same amount. He spends 32$ on the pizza and the sodas together
ziro4ka [17]

Answer: See explanation

Step-by-step explanation:

Yiur question isn't complete but I believe that you want to know the price of the soda.

Let the price of the soda be represented by x.

Jesean buys a pizza for 20$ and 10 drinks. This will be: 20 + 10x

He spends 32$ on the pizza and the sodas together. This can be formed into an equation as:

20 + 10x = 32

10x = 32 - 20

10x = 12

x = 12/10

x = 1.2

Therefore, the soda cost $1.20 each

The following questions are related to problems on simple fraction and arithmetic. Hence, the solutions to the questions are as follows :

1.)

Time on mathematics =<em> 1 hour</em>

Time on science homework = <em>7/8</em><em> hours</em>

Total time spent = (1 + 7/8) = 1 \frac{7}{8}

2.)

Total number of students = <em>60</em>

Fraction of girls = <em>3/4</em>

Fraction of boys = 1 - 3/4 = 1/4

Number of boys = 1/4 × 60 = 15 boys

3.)

Initial temperature = <em>- 2°C</em>

Final temperature = <em>8°C</em>

Change in temperature = Final temperature - Initial temperature

Change in temperature = (8 - (-2)) = 8 + 2 = 10°C

4.)

Elevation of everest = <em>20028 feets </em>

Elevation of dead sea =<em> - 485 feets</em>

Difference in elevation = (20028 - (-485)) = 20513 feets

5.)

Question is missing key values.
