Artist 52 [7]

(x - 3) + (x - 6) + x = 63
x - 3 + x - 6 + x = 63
Combine like terms
3x - 9 = 63
Isolate the constant
3x - 9 + 9 = 63 + 9
3x = 72
Isolate the viable
3x / 3 = 72 / 3

Bryn's age is given by the expression 3g - 7, where g is her sister Gabriela's age. If Bryn is 17, how old is Gabriela?

lutik1710 [3]

You are told that B=3g-7 and you are also told that B=17 so

3g-7=17 add 7 to both sides

3g=24 divide both sides by 3

g=8

So Gabriela is 8 years of age.

Answer:

Benjamin travels 7 meters in 100 seconds.

Step-by-step explanation:

We are given the following in the question:

Circumference of tire = 2.8 m

Revolution of time = 1.5 times per minute.

Total time = 100 seconds.

We have to calculate distance covered by Benjamin.

Total number of revolution of tires =

$=\text{Revolution rate}\times \text{Time}\\\\=1.5\text{ revolution per minute}\times \dfrac{100}{60}\text{ minutes}\\\\=2.5 \text{ revolutions}$

Total distance covered by Benjamin =

$=\text{Number of revolution of tires}\times \text{Circumference of tire}\\=2.5\times 2.8\\=7\text{ meters}$

Thus, Benjamin travels 7 meters in 100 seconds.
