Solve the following equations:

x/3+1=7/5

Answers

Answer:

8/5..............…is the answer

Answer:

Standard Form: 6/5 Mixed Number: 1 1/5 Decimal: 1.2

Step-by-step explanation:

1. Subtract 1 from both sides of the equation

x/3 + 1 = 7/5

x/3 + 1 - 1 = 7/5 - 1

2. Simplify

2a.

x/3 + 1 - 1 = 7/5 - 1

x/3 = 7/5 - 1

2b.

x/3 = 7/5 - 1

x/3 = 2/5

3. Multiply all terms by the same value to eliminate fraction denominators

x/3 = 2/5

3 x x/3 = 3 x 2/5

4. Simplify

4a. Cancel multiplied terms that are in the denominator

cross out the threes in 3 x x/3 then you should get x = 3 x 2/5

4b. Multiply the numbers

x = 3 x 2/5

x = 6/5

And your answer should be 6/5|

I hope this helps you or anyone

What is the vertex for the quadratic
y = 2(x-3)^2 - 4? Type as (h.k)

Answers

Answer:

(3,-4)

Step-by-step explanation:

You can find the vertex where x = -b/2a

To find the values of a and b, it would be easier to write the equation in standard form, which is y = ax^2 + bx + c

y = 2(x^2 - 6x + 9) - 4

y = 2x^2 - 12x + 18 - 4

y = 2x^2 - 12x + 14

In this equation, a = 2 and b = -12.

So let's plug that into x=-b/2a

x = -(-12)/2(2)

x = 12/4

x = 3

Now we have the x, we can just plug that into the original equation and get the y coordinate for the vertex.

y = 2(x - 3)^2 - 4

y = 2(3 - 3)^2 - 4

y = -4

Answers

Answer:

100% is 9, 55% is 4.95, 75% is 6.75.

Step-by-step explanation:

Suppose that 100% were [tex]x[/tex]. Then 30% is 27, so [tex]0.3x=27[/tex] and we can divide both sides by 0.3 to see that [tex]x=\frac{27}{0.3}=\frac{27}{\frac{3}{10}} = \frac{27\cdot 10}{3} = 90.[/tex] So 55% is [tex]0.55x = 0.55 \cdot 9 = 4.95[/tex] and 75% is [tex]0.75x = 0.75\cdot 9=6.75[/tex]. (Note that we can divide the value of a percentage by 100 - the same as moving the comma by two places to the left - to get the decimal value.)

Mf what figure ????????

Katrina bought a new sofa. She was able to pay $100 at the
time she received the sofa. She will pay $22 each month on
the balance. The original cost of the sofa was $298. The
equation 100 + 22 = 298 represents this situation.
Use the equation to determine how many months will it take
Katrina to pay off the sofa.

Answers

Answer:  9 months

================================================

Work Shown:

100 + 22x = 298

22x = 298-100  ........ subtracting 100 from both sides

22x = 198

x = 198/22 .............. dividing both sides by 22

x = 9

It will take 9 months for her to pay off the sofa.

She pays the original $100, and then on top of that, she pays an extra 22*x = 22*9 = 198 dollars since she paid $22 per month for 9 months. So this leads to 100+198 = 298 dollars total to help confirm our answer.

Solve: 3n - 6 = -8(6 +5n)
and explain how to solve it

Answers

Answer:

Step-by-step explanation:

First use distributive property: a(b + c) = a*b + a*c

3n - 6 = -8(6 + 5n)

3n - 6 = 6 * (-8) + 5n *(-8)

3n - 6 = -48 - 40n

Now add 40n to both sides

3n - 6 + 40n = -48 - 40n + 40n

43n - 6 = -48

Now add 6 to both sides

43n - 6 + 6 = -48 + 6

           43n = -42

               n = -42 /43

Answer:

0.98

Step-by-step explanation:

3n-6=-8(6+5n)

3n-6=-48-40n

3n=-48-40n+6

40n+3n=-42

43n=-42

n=0.98 (I rounded it)
