Answer:  YES, Geoffrey can buy the video game.

Step-by-step explanation:  Given that Geoffrey is trying to earn $50 to buy a video game. He has saved $14.25. He earns $3.75 per hour cleaning windows with his uncle and he earns $6.50 per hour working at the grocery store.

We are to find whether he can buy the video game if he works with his uncle for 3 hours and at the grocery store for 4 hours.

We will be using the following inequality :

3.75y + 6.50z + 14.25 ≥ 50.

According to the given information, we have

y = 3  and  z = 4.

Therefore, we get

 3.75y + 6.50z + 14.25

= 3.75 ×3 + 6.50 × 4 + 14.25

= 11.25 + 26 + 14.25

= 37.25 + 14.25

= 51.50 > 50.

Therefore, Geoffrey can buy the video game.

Hatshy [7]

Answer:

53 minutes

Step-by-step explanation:

Let x be the time required for a full video upload.  This would have the unit of (minutes/full upload).  Since the upload rate is constant, we can write:

(0.17)*(x) = 9 minutes

This equation states that 17% of the full upload time is 9 minutes.

Solve for x:

x = (9 minutes)/(0.17)

x = 52.9 minutes or 53 minutes with 2 sig figs

If the measures of two angles of a triangle are 87 and 17 ​, what is the measure of the third​ angle
Serhud [2]

Answer:

76 degrees

Step-by-step explanation:

The total of the three angles in a triangle should equal 180 degrees. So to find the third angle, subtract the two given angles from 180

180 - 87 = 93

93 - 17 = 76

The third angle is 76 degrees because then all angles will add up to 180
