Answer:

q = r

Step-by-step explanation:

<u><em>Explanation:-</em></u>

Given    2q – r = 4p ...(i)

                  2r = q...(ii)

                  r = 2p ...(iii)

Substitute 2r = q in equation (i)

            <em>   2(2r) – r = 4p </em>

                     3 r = 4 p

                 <em>  2 r + r = 4 p</em>

                   2 r + 2 p = 4 p

                  2 r = 2 p

                 <em>  q = r</em>

Angles A = 60, B = 2x, C = 3x and D = 25 are 4 angles on a straight, what 3 points is the value of angle B?*​
iragen [17]

Answer:

  B = 38°

Step-by-step explanation:

A straight angle is 180°. If your four angles total a straight angle, then ...

  60 +2x +3x +25 = 180

  95 = 5x . . . . . . subtract 85

  x = 19 . . . . . . divide by 5

  2x = 38 . . . . . angle B is 38°

What is g(x)?<br> A. g(x) = -2<br> B. g(x) = -x<br> C. g(x) = -|x|<br> D. g(x) = -x^2
Nastasia [14]

Answer:

A. g(x) = -2^x.

Step-by-step explanation:

If g(x) = -2, it would be a straight line running horizontally.

If g(x) = -x, it would be a linear equation.

If g(x) = -|x|, it would be an absolute value function, which is a graph in a v-shape.

So, the remaining answer is that A. g(x) = -2^x.

Hope this helps!

7,500 is 35% of what?
earnstyle [38]

Answer:

21428.57

Step-by-step explanation:

Steps to solve "7500 is 35 percent of what number?" We have, 35% × x = 7500 or, 35 100 × x = 7500 Multiplying both sides by 100 and dividing both sides by 35, we have x = 7500 × 100 35 x = 21428.57 If you are using a calculator, simply enter 7500×100÷35, which will give you the answer.

Answer:

The expressions that give the value of y are A - 3B and (1/3)A - B

The solution is (27/13, -60/13)

Step-by-step explanation:

We can see both equation A and equation B.

Equation A: 2x + (1/4)y = 3

Equation B: (2/3)x - y = 6

To find the value of y, we have to solve both equations A and equation B simultaneously. This is done by multiplying equation B by 3 and subtracting from equation A (A - 3B) to get:

(13/4)y = -15

y = -60/13

you can also get y by dividing equation A by 3 and subtracting equation B (1/3A - B)

Put y = -60/13 in equation A to get x:

2x + (1/4)(-60/13) = 3

2x = 3 + 15/13

2x = 54/13

x = 27/13

The solution is (27/13, -60/13)
