dedylja [7]
<span>In the fairest school 20% are below 16 years old
1/3 are teachers which is equals to = 21
Let’s start solving:
=> 1/3 of 100% = ( 100 / 3 = 33.33% )
thus 33.33% = 21
=> 21 x 3 = 63, is the total number of people in the school.
Let’s try solving the number of people below 16 years old
Then there are 20% of it:
=> 63 * .20 = 12.6
Thus, there are around 13 people who are 16 years old younger.</span>

I need help with geometry!
ss7ja [257]

Step-by-step explanation:

If m is parallel to n and one of its angle is 25

Therefore, the vertically opposite angle to angle of 25 is also equal to 25

Now, we have to find x

Therefore, x=180-25 ( interer angles on the same side of the transversal so addition of both angles is 180)

Therefore, x =155

Polo shirts come in two colors- white and blue. There are 18 more white polo shirts than blue polo shirts. The white polo shirts
MAVERICK [17]

Answer:

The total number of polo shirts is 50

Step-by-step explanation:

Let

x -----> the number of white polo shirts

y -----> the number of blue polo shirts

we know that

x=y+18 -----> equation A

68\%=68/100=0.68

x=0.68(x+y) ------> equation B

substitute equation A in equation B and solve for y

y+18=0.68(y+18+y)\\ y+18=0.68(2y+18)\\ y+18=1.36y+12.24\\ 1.36y-y=18-12.24\\ 0.36y=5.76\\ y=5.76/0.36\\ y=16\ blue\ polo\ shirts

<u><em>Find the value of x</em></u>

x=16+18=34\ white\ polo\ shirts

<u><em>Find the total number of polo shirts</em></u>

x+y=34+16=50\ polo\ shirts
