Answer:

15/21

Step-by-step explanation:

First do 5 times 3, which is 15 (5+5+5). Then do 7 times 3, which is 21 (7+7+7). Since the denominator is 7 and there is 3 models with 7 parts each, there are 21 total parts. Out of each model, only 5 parts are highlighted/colored out of the 7. Add all the parts that are colored together to get 15. To put it simpler, 15 out of 21 parts are colored. This cannot be further simplified, giving you 15/21

Solve 6x-54=6(x-9)<br><br> show work please

Stolb23 [73]

Answer:infinite

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

6x−54=6(x−9)

6x+−54=(6)(x)+(6)(−9)(Distribute)

6x+−54=6x+−54

6x−54=6x−54

Step 2: Subtract 6x from both sides.

6x−54−6x=6x−54−6x

−54=−54

Step 3: Add 54 to both sides.

−54+54=−54+54

samantha threw an apple out of a window from the tenth floor of her appartment building. the equation y = -16t^2+120 can be used

ella [17]

Answer:
time taken = 2.74 seconds

Explanation:
We are given that:
y = -16t² + 120 models the situation where:
y is the floor number
t is the time taken for the apple to hit the ground

We are also given that the floor number (y) is 10. Therefore, all we have to do is substitute with y in the above equation and solve for the time t as follows:
y = -16t² + 120
10 = -16t² + 120
120 - 10 = 16t²
110 = 16t²
t² = 110/16
t² = 6.875
either t = 2.74 seconds ..........> accepted
or t = -2.74 seconds .........> rejected as time cannot be in negative

Hope this helps :)
