Please Answer! Very Easy And Will Mark Brainlist.

Answers

Answer 1

Answer:

18.57

Step-by-step explanation:

First you have to simplify the equation using cross-multiplication

You should get 7v=130

Then divide both sides by 7

You should get v=130/7

simplify that and get 18 4/7

Turn that into decimal form and you get 18.57

Answer 2

Answer:

18.57

Step-by-step explanation:

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

v/10 = 13/7

10 x v/10 = 10 x 13/7

2. Simplify

130/7 = 18.571428571429

3. Round to the Nearest Tenth

18.57

Question: (3x-2)² + (2x-4)² = 3

Answer:

When squaring things, we are just multiplying it by itself (a² = a x a). When squaring brackets, it’s the same rule:

Therefore:

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

And using this skill we get:

(3x-2)(3x-2) + (2x-4)(2x-4) = 3

Using FOIL:

9x²-6x-6x+4 + 4x²-8x-8x+16 = 3

Simplify:

13x²-28x+20 = 3

Take -20 off from both sides:

13x²-28x = -17

There’s your answer!

I hope this made sense, if you have any questions or you think I made a mistake somewhere please let me know!

2(2x - 8) > 4(3x - 12) Solve the inequality (Just like my previous problem) Make sure to show work!!

Answers

2(2x-8)
2•2x=4x
2•-8= -16
So now 4x-16
Now divide both sides by 4
4x/4=x
-16/4=-4
X=-4

Answer:

x < 8

Step-by-step explanation:

This is a special case, so at the end of the equation we'll flip the sign.

Distribute:

2 * 2x = 4x

2 * -8 = -16

4x - 16

4 * 3x = 12x

4 * -12 = -48

12x - 48

4x - 16 > 12x - 48.

Subtract 12 from both sides.

12 - 12 = 0

4x - 12x = -8x

-8x - 16 > -48

The additive inverse of subtraction is addition so do -16 + -48, which equals -64

-8x/-8 = x

-64/-8 = 8

Now this is where we flip our sign so here we go :)

x < 8

There.

Hope this helped and sorry if I'm wrong.
