x/5=5+x-9/3 what’s the solution? show work please

Answers

Answer 1

Answer:

x = - 15

Step-by-step explanation:

Given

[tex]\frac{x}{5}[/tex] = 5 + [tex]\frac{x-9}{3}[/tex]

Multiply through by 15 ( the LCM of 5 and 3 ) to clear the fractions

3x = 75 + 5(x - 9) ← distribute and simplify right side

3x = 75 + 5x - 45

3x = 5x + 30 ( subtract 5x from both sides )

- 2x = 30 ( divide both sides by - 2 )

x = - 15

As a check

substitute x = - 15 into the equation and if both sides are equal then it is the solution.

left side = [tex]\frac{-15}{5}[/tex] = - 3

right side = 5 + [tex]\frac{-15-9}{3}[/tex] = 5 + [tex]\frac{-24}{3}[/tex] = 5 - 8 = - 3

Thus x = - 15 is the solution

Write an exponential function whose graph passes through the points (0,-2) and (2,-50)

Answers

Answer:

first sub in (0,-2) to get

-2 = ab^0, but b^0 = 1

so a=-2

so far we have

y = -2b^x

now use the other point (2,-50)

-50 = -2(b^2)

b^2 = 25

b= ±5

however in exponentional equations the base is usually positve, so now you have

y = -2(5^x)

sub in x=-2 and you got it.

l=prt
you have to solve for t

Answers

Answer:

T is equal to I divided by pr. [tex]t=\frac{I}{pr}[/tex]

Step-by-step explanation:

This is the equation for interest.

I is interest.

P is the principal

r is the interest rate

t is the time in years

you have to isolate for t.

Because multiply p times r times t, divide both sides by pr due to the fact that division is the inverse operation of multiplication

Then you are left with t= i divided by pr.

Work out

137% of 720.11kg

Give your answer rounded to 2 DP.

Answers

Answer:

The answer is 986.55 kg.

Step-by-step explanation:

When asked to find 137% of 720.11 kg, we can take the percentage, 137%, and convert it into a decimal by moving the decimal point over to the left twice.

137% = 1.37

After converting the percentage to a decimal point, we can multiply the original given value by the decimal.

720.11 kg x 1.37 = 986.5507 kg

And then we round to the nearest hundredths place, which will give us 986.55 kg.

The required evaluation of 137% of 720.11 kg would be 986.55 kg.

What is the percentage?

The percentage is defined as a ratio expressed as a fraction of 100.

We have to determine the evaluation of 137% of 720.11 kg.

⇒ 137% of 720.11

137% is expressed as 15/100 in fractional form

⇒ (137/100)(720.11 )

137/100 is expressed as 0.95 in decimal form

⇒ (1.37)(720.11 )

Apply the multiplication operation, and we get

⇒ 986.55

Therefore, 137% of 720.11 kg would be 986.55 kg.
