PLS HELP!!! WILL MARK BRAINLIEST!!!!!!!!!

Answer:

A is the correct answer

Step-by-step explanation:

If you plug y=x+10 in for the Y variable you just have to solve by multiplying.

1.) It should look like this:

2x + 3(x +10) = 40

2.) You will distribute the three which will make the equation look like this:

2x + 3x + 30 = 40

3.) Add like terms. Then subtract 30 from both sides. Then divide 5 by both sides to get the variable x alone.

Hope that helps

Answer:

[tex]\sqrt{2n^{2}}[/tex]

You have the side lengths of the two legs, n and n.

Then, using the pythagorean theorem you have to find the length of the third side:

[tex]a^2 + b^2 = c^2\\n^2 + n^2 = c^2\\2n^2 = c ^ 2\\\sqrt{2n^2} = c[/tex]

where c is the third side

Answer: G) 50.24

Step-by-step explanation: you have to find the circumference of the circle. Since you already have the diameter which is 16 all you have to do is multiply that by 3.14. If you only had the radius then you will have to multiple the radius times 2 times 3.14. The formulas for circumference are: pi(3.14) x diameter or pi(3.14) x radius x 2

Answer:

x=7

Step-by-step explanation:

1.     -2x+3=-11  << first make sure the x is one one side of the equal sign. so  remove the 3, by subtracting if from 11

2. -2x+3=-11

         -3   -3

         =

3.  -2x= -14    <<  then so isolate the x= divide -2 from -14 (two negatives divided equals a positive)

4. x=7

Answer:

Step-by-step explanation:

The sales tax rate is 8%.

The correct option is (b).

The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.

For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.

12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.

As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.

This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.

Given:

Jenny bought scrapbooking supplies for $145.00.

She paid $11.60 in sales tax.

let the tax rate be x%.

So, the price without sales tax = 145 - 11.6 = $133.4

Thus, x% of 133.4 = 11.6

133.4 x = 1160

x = 8.65%

x= 8%

Hence, the tax rate is 8%.

Answer:

-6x+7

Step-by-step explanation:

Start by multiplying (x-1) by -4 and (x+1) by -2.

Then you will have the equation 5-4x+4-2x-2

Next, just find your like-terms.

Your like-terms are 5,4,-2 and -4x, 2x

Then, for easier for calculation, just use the equation:

-4x-2x+5x+4-2

Your final answer should then be:

-6x+7

Answer:

Length = 18 meters

Step-by-step explanation:

Let the length of the rectangular pool = l meters

And breadth of the pool = w meters

Perimeter of the rectangular pool = 2(l + 2w)

Since, perimeter of the rectangular pool is 72 meters.

2(l + 2w) = 72

l + 2w = 36 --------(1)

If length of the pool is twice of its breadth,

l = 2w

w = [tex]\frac{l}{2}[/tex] -------(2)

By substituting the value of 'w' from equation (2) to equation (1),

[tex]l+2\times{\frac{l}{2}}=36[/tex]

2l = 36

l = 18 meters

Answer:

  a, b, e (only)

Step-by-step explanation:

The circle centered at A is all of the points that are distance AB from A.

The circle centered at B is all of the points that are distance AB from B.

The points C and D are points that are distance AB from both A and B.

The line joining those points (C and D) consists entirely of points that are equal distances from A and from B. CD is the perpendicular bisector of AB.

Point M is one of the points on line CD, and is also on segment AB. Because it is on CD, we know it is the same distance from A as from B. That means AM = BM, and M is the midpoint of AB.

__

Points B, C, D are not on the same line, so can form a triangle. As with any triangle, the sum of any two segments is greater than the length of the third. Here, this is expressed as CB + BD > CD.

__

With some work using the Pythagorean theorem, you can show that ...

  CM = AM×√3

Similarly, MD = BM×√3.

Adding these two relations tells us ...

  CM +MD = √3(AM +BM)

  CD = AB×√3 . . . . . AB and CD are not the same length

__

AM and BM are on the same line, so cannot be perpendicular to each other.

Answer:

x= 3/4

Step-by-step explanation:

[tex](3x - 2) = \frac{(2x-1)}{2}[/tex]

2(3x - 2) = (2x - 1)

6x - 4 = 2x -1

4x = 3

x= 3/4

Answer:

x=3/4

Step-by-step explanation:

Remove parentheses.

3x-2=\frac{2x-1}{2}3x−2=22x−1

Multiply both sides by 22.

6x-4=2x-16x−4=2x−1

Add 44 to both sides.

6x=2x-1+46x=2x−1+4

Simplify  2x-1+42x−1+4  to  2x+32x+3.

6x=2x+36x=2x+3

Subtract 2x2x from both sides.

6x-2x=36x−2x=3

Simplify  6x-2x6x−2x  to  4x4x.

4x=34x=3

Divide both sides by 44.

x=\frac{3}{4}x=43
