Step-by-step explanation:

$\\ \frac{x. {x}^{ - 2} }{ {x}^{ - 1}. {x}^{0} } = \frac{{x}^{ - 2 + 1} }{ {x}^{ - 1}.1 } = \frac{{x}^{ - 1} }{ {x}^{ - 1} } = 1$

Sedbober [7]

Answer:

Answer is 135 plant

Step-by-step explanation:

We have given that,

In 5 min Renee can plant 15 plant.

That means in one minute Renee can plant $\frac{15}{5}$ plant.

i.e. Rate of planting = 3 plant per minute

So, In 45 minutes , she can plant 45×3 plant

i.e Plant she can plant in 45 minute = 135 plant

-26 times a number minus 22 is equal to 90 less than the number.

IgorLugansk [536]

Answer:

$x = \frac{68}{27}$

Step-by-step explanation:

Let x be the number

Write it out: -26x - 22 = x - 90
Combine like terms: -27x + 68 = 0
Subtract 68 from each side, so it now looks like this: -27x = -68
Divide each side by -27 to cancel out the -27 next to x. It should now look like this: $x = \frac{68}{27}$

I hope this helps!

Two cars travel at the same speed to different destinations. Car A reaches its destination in 17 minutes. Car B reaches its dest

Goryan [66]

Answer:

speed of car A =Speed of car B=0.8 miles/minutes.

Step-by-step explanation:

We are given that speed of car A is equal to speed of car B.

Also let car A travels x miles.

and car B travels y miles.

Car A reaches its destination in 17 minutes.

this means that speed of car A is given by: $\dfrac{x}{17}$ miles/minutes ( since speed is defined as the ratio of distance and time).

Car B reaches its destination in 32 minutes.

This means that the speed of car B is given by: $\dfrac{y}{32}$ miles/minutes

as speed of both cars are equal this means:

$\dfrac{x}{17}=\dfrac{y}{32}$ ------(1)

Also we are given Car B travels 12 miles farther than Car A.

this means $y-x=12$

$y=12+x$ ------(2)

on using equation (1) and (2) we have:

$\dfrac{x}{17}=\dfrac{12+x}{32}\\ \\32x=17(12+x)\\\\32x=17\times12+17x\\\\32x-17x=17\times12\\\\15x=122\times17\\\\x=13.6$

Hence the speed of car A is 0.8 miles/minutes ( since x/17 is the speed of car A)

Speed of car B=0.8 miles/minutes.
