Answer:

The answer is that x ⁻³ is equivalent to x²/x⁵ without a factor bar

Step-by-step explanation:

Write without factor:

x²/x⁵ = x²⁻⁵ = x ⁻³

The answer is that x ⁻³ is equivalent to x²/x⁵ without a factor bar

When Klorina swims with the current, she swims 10 km in 2 h. Against the current, she can swim only 8 km in the same time. How f

nasty-shy [4]

Answer:

Klorina's rate in still water is 4.5 km/h

Current's rate is 0.5 km/h

Step-by-step explanation:

Let

x km/h = Klorina's rate in still water

y km/h = current's rate

With the current (current helps):

Distance = 10 km

Time = 2 hours

Rate = x + y km/h

$10=2(x+y)$

Against the current:

Distance = 8 km

Time = 2 hours

Rate = x - y km/h

$8=2(x-y)$

Divide both equations by 2:

$x+y=5\\ \\x-y=4$

Add these equations:

$x+y+x-y=5+4\\ \\2x=9\\ \\x=4.5\ km/h$

Subtract these two equations:

$(x+y)-(x-y)=5-4\\ \\x+y-x+y=1\\ \\2y=1\\ \\y=0.5\ km/h$

Please help right now please

Answer:

A or 24

Step-by-step explanation:

In PEMDAS you do the steps from left to right in the name.

So first, you do 3 * x and x = 6 so 3 * 6 which is 18.

then 18 + y and y = 8 so 26

26 minus 2 is 24.

Hope this helped~ ^-^

Solve the proportion and round your answer to the nearest tenth.

GalinKa [24]

Answer:

y = 1.1

Step-by-step explanation:

Proportion is a statement that two ratios are equal.

It can be written in two ways:

Two equal fractions $\frac{a}{b}$ = $\frac{c}{d}$

Two equal sides a: b = c: d.

We can use cross products to find a missing term in it.

Let us solve the question

∵ The proportion statement is $\frac{7.7}{15.4}$ = $\frac{y}{2.2}$

→ Use the cross multiplication to find y

∵ y × 15.4 = 7.7 × 2.2

∴ 15.4y = 16.94

→ Divide both sides by 15.4 to find y

∵ $\frac{15.4y}{15.4}$ = $\frac{16.94}{15.4}$

∴ y = 1.1

No need to round it to the nearest tenth because the answer has no hundredth to round it to the tenth

Simplify the expression

erastova [34]

Answer : A

We need to simplify the given expression

Lets factor numerator first

$2x^2-5x-3$ =(2x+1)(x-3)

$x^2+8x+15$ =(x+5)(x+3)

Now we factor the denominator

$x^2+x-20$ =(x+5)(x-4)

$2x^2+9x+4$ =(2x+1)(x-4)

Now we simplify it

$\frac{(2x+1)(x-3)}{(x+5)(x-4)} * \frac{(x+5)(x+3)}{(2x+1)(x-4)}$

Now cancel out same factors. so we left with

$\frac{(x+3)(x-3)}{(x+4)(x-4)} }$

Now multiply the factors

$\frac{x^2-9}{x^2-16} }$
