Answer: 26

Step-by-Step: Since the two angles are supplementary (or when put together form a line which is 180 degrees), write an equation like this.

5x + (x+24) = 180
\/
6x + 24 = 180
-24 -24
6x = 156
/6 /6

= 26

Hope it helps!

HACTEHA [7]

Answer:

Step-by-step explanation:

So, to go about your question, we must first ask, how many hours a week is being worked?

In this problem, that is 9 hours per week.

Next, we must question how much per week is made

That is $92 per week

Finally, we must determine if the allowance is occuring many times in the week or just once.

In this problem, that is only occuring once for the week.

So, the equation we must setup is 9x +20 =92.

To solve the equation, we need to subtract 20 on both sides to isolate the variable, x.

9x+20=92

-20 -20

Now our equation is

9x=72

Now, to finally get x by itself or to isolate x, you should divide 9 on both sides to cancel out the 9 being multiplied by the x.

9 9

x=8 because of 72/9 is equal to 8.

I hope this helps, and I will answer any questions you have.

valina [46]

Answer:

Step-by-step explanation:

l -> length

b -> width

h -> height

Find the area of four walls and ceiling. then subtract the area of four windows and a door form that area.

Area of four walls + <u>ceiling</u> = 2( lh + bh) +<u>lb</u>

= 2*(20*5 + 15*5) + 20*15

= 2( 100 + 75) + 300

= 2* 175 + 300

= 350 +300

= 650 sq m

Area of window = 2 *3 = 6 sq.m

Area of four windows = 4*6 = 24 sq.m

Area of door = 2 * 1 = 2 sq.m

Area of four walls excluding 4 windows and door = 650 - 24 - 2 = 624 sq.m

Cost of painting = 624 * 6.50

= $ 4056

What is 3/4 of 16/21? worked out please

timofeeve [1]

Of means multiplication

So

$\frac{3}{4} \sf{of} \frac{16}{21} = \frac{3}{4} \times \frac{16}{21}$

And then simplify the numerator ad denominator

= $\frac{3 \times 16}{4 \times 21} = \frac{\ 1 \times 16}{4 \times 7}$

And simplify the numerator and denominator again

= $\frac{\ 1 \times 16}{4 \times 7} = \frac{\ 1 \times 4}{1 \times 7}$

And we are finally left with the answer which is $\frac{4}{7}$
