LN is congruent to NQ so because of that you set both equal to each other

7x=5x+20

Subtract 5x on both sides

7x-5x=20

2x=20

x=10

Hope this helps!! Mark for brainliest

Solve. Use the strategy "work backward."

cestrela7 [59]

Let that be x

ATQ

$\\ \rm\Rrightarrow 3x-6/5=9$

Arrange accordingly to work backwards(Every thing is reversed)

$\\ \rm\Rrightarrow 9(5)+6/3=x$

$\\ \rm\Rrightarrow 45+6/3=x$

$\\ \rm\Rrightarrow 51/3=x$

$\\ \rm\Rrightarrow x=17$

Answer:

1. 8.19, 2. 25.96, 3. 3.95

Step-by-step explanation:

use soh cah toa

1. cos is adjacent/hypotenuse

cos73=x/28

multiply both sides by 28

28cos73=x=8.186

2. sin is opposite over hypotenuse

sin68=x/28

multiply both sides by 28

28sin68=x=25.961

3. sin is opposite over hypotenuse

sin26=x/9

myltiply both sides by 9

9sin26=x=3.945

Last year there were 145 pies baked for the bake sale this year k pies baked using k write a expression for the total number of

allsm [11]

Answer:

The number of pies baked in the two years = ( k + 145) pies

Step-by-step explanation:

Here, we are interested in writing an expression for the total number of pies baked in the two years.

Last year, the number of pies baked = 145

This year the number of pies baked = k

Thus, the total number of pies baked in the two years will be ( k + 145) pies

The area of the circle is 144π m2<br><br> What is the diameter of the circle?

Over [174]

Answer:

Step-by-step explanation:

Remember that

Area of Circle = $\pi r^2$

$\pi = pi \\r = radius$

They told us that for this circle, the area is $144\pi m^2$

If you put it back into the formula for area of a circle we get:

Area of Circle = $\pi r^2$

$144\pi = \pi r^2$

Divide both sides by $\pi$ .

144 = $r^2$

Now we want to solve for r (r = radius).

You need to square root each side

$\sqrt{144} = \sqrt{r^2}$

$12 = r$

So now we know the radius, $r = 12$ metres

Also remember that

Diameter = $2r$

So,

Diameter = 2 times 12 = 24 metres
