x = -0.583 (continuing) or -7/12

Answer:

x= -7/12

Step-by-step explanation:

Subtract the numbers

-3x+2-5x-7=4x+2

-3x-5-5x=4x+2

Combine like terms

-3x-5-5x=4x+2

-8x-5=4x+2

Add 5 to both sides of the equation

-8x-5=4x+2

-8x-5+5=4x+2+5

2. Find the midpoint of PQ.

Answers

Answer:

c) (-2, -1)

Step-by-step explanation:

to find the midpoint of a line, u have to average its coordinates.

Coordinates of P = (2,6)

Coordinates of Q = (-6, -8)

The formula for finding the midpoint is this:

[tex](\frac{x_{1}+x_{2} }{2}, \frac{y_{1}+y_{2} }{2 } )[/tex]

this basically means u average the points. So for the midpoint's x coordinate, it'll be (2-6)/2 = (-4)/2 = -2

midpoint's y coordinate = (6-8)/2 = (-2)/2 = -1

Therefore, the coordinates of the midpoint are (-2, -1), option c

hope this helps!

Answer:

C

Step-by-step explanation:

Remark

Just eye balling the answer it looks to me like the midpoint is (-2,-1). Of course Eyeballing it is not the way to do math, but it tells you where it is approximately.

Given Points

P: (2,6)

Q: (-6,-8)

Solution

midpoint = (x1 + x2)/2, (y1 + y2)/2

midpoint = (2 + - 6)/2, (6 - 8)/2

midpoint = (-4/2, -2/2)

midpoint = (-2,-1)

Step-by-step explanation:

let the said number be x

Nineteeen less than 6 times a number;

6x - 19

equals; 16 more than the number; this is 16 + x

Thus;

6x - 19 = 16 + x

6x-x = 16 + 19

A pair of shoes is on sale for 80% of the original price. The sale prive is $60. What was the original price?

Answers

Answer:

75

Step-by-step explanation:

You will set the equation up as part/whole = percent/100 and when you replace it with your numbers you get 60/x = 80/100 now you cross multiply and do 60*100 = 80 * x and you get 6,000 = 80x now you divide both sides by 80 then you get 75 was the original price

Two coaches each buy 1 soccer ball for $12 and 4 cones. Each cone costs the same amount.
Together the coaches spend $40. How much does each cone cost?
( write an equation to model the situation. Then solve for x)

Answers

Answer:

x=16

Step-by-step explanation:

1 soccer ball =$12

2 makes $24.

24+16=40

so both coaches spend 8 bucks for 4 cones

Each cone costs $2, and the cost is calculated as follows: 8x = 40 - 2 *p, where p is equal to the cost of a football.

What is a Linear equation?

A linear equation is an algebraic equation of the form ax + by +c, is and only a constant and a first-order (linear) term are included. Sometimes, the aforementioned is referred to as a "linear equation of two variables," with y and x serving as the variables.

Given that, Two coaches each buy 1 soccer ball for $12 and 4 cones. Each cone costs the same amount. Together the coaches spend $40.

Let x be the number price of the cone.

Thus each coach spends  = 4x  +12

Thus, in total, they spend = 40

4x  +12 +  4x  +12 = 40

8x = 40 -24

8x = 16

x = 2

Therefore, Each cone costs $2 and the equation for calculating the price of the cone is: 8x = 40 - 2 * the price of a football.

Urgent help on math plz

Answers

Answer:

x = 14

Step-by-step explanation:

First, organize your work by showing that lines are similar

Line KV is similar to line RV

Line UV is similar to line LV

etc, etc.

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

Now notice that line KV and line RV have the numbers 9 and 18 accordingly

and notice that it's an x2 difference.

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

Now apply the same thing to line UV and LV and divide 26 by 2

That gets us 13

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

Now plug 13 into the equation (2x - 15)

2x - 15 = 13

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

Now solve for X

2x - 15 = 13

Add 15 to each side

2x − 15 + 15 =13 + 15

2x = 28

Divide both sides by 2

2x / 2 = 28 / 2

x = 14
