Answer:

  • x=3

Step-by-step explanation:

\sf 14=-6+2\left(2x+4\right)

\sf -6+2\left(2x+4\right)=14

\sf -6+2\left(2x+4\right)+6=14+

\sf 2\left(2x+4\right)=2

\sf \frac{2\left(2x+4\right)}{2}=\frac{20}{2}

\sf 2x+4=10

\sf 2x+4-4=10-4

\sf 2x=6

\sf \frac{2x}{2}=\frac{6}{2}

\sf x=3

Points P, Q, and S are collinear. What is m∠PQR? Straight angle P Q S is divided into 2 angles, P Q R and R Q S, by ray Q R. Ang
andreyandreev [35.5K]

Answer:

Step-by-step explanation:

If P, Q and S are collinear, then the three points lies on the same straight line.

If the Straight <P Q S is divided into 2 angles, <P Q R and <R Q S, by ray Q R, then;

<P Q R + <R Q S = 180

Given

<R Q S =x+1

<P Q R = 3x-5

Substitute the given expression into the formula and calculate x;

3x-5+x+1 = 180

collect like terms

3x+x - 5+1 = 180

4x-4 = 180

4x = 180+4

4x = 184

divide both sides by 4

4x/4 = 184/4

x = 46°

To get m∠PQR, we will substitute x = 46 into the expression for m∠PQR.

m∠PQR = 3x-5

m∠PQR = 3(46) - 5

m∠PQR = 138 - 5

m∠PQR = 133°

Hence the measure of angle m∠PQR is 133°

Suppose that 13 inches of wire costs 52 cents. At the same rate, how many inches of wire can be bought for 32 cents?
kirill115 [55]

Answer:

So we have a ratio which you have specified 13:52. So we just need to get the same ratio for 13. 32/52 is how we get 32 from multiplying by 52. So now we just need to multiply it for 13 also'

13*32/52 = 8. Therefore the answer to this is 8

Find the area of each figure, round to the nearest tenth if necessary.USE 3.14 for pi
Nina [5.8K]

Answer:

11 is 405, 12 is 107.5, 13 im not sure of

Step-by-step explanation:

First on 11 you can just do 21*21 (the big square) and subtract that by 36 (which is 6*6, the small square), you'll get 107.5.

Then on 12, it is made up of a large rectangle, a small triangle, and a flatter triangle. The top triangle's formula is 1/2(7*3) which = 10.5. The big rectangle is 13*7 = 91. The last triangle is 1/2(4*3) which = 6. It is 3 because 13-10. Add all those up and you should get 107.5.

And I just want to know on number 13 if that 11 is the radius or diameter. I can't seem to tell.
