Answer:
Four boys and one girl.
Step-by-step explanation:
Total students wearing glasses = 5
Separate the students by x and x + 3. It is x + 3 for the boys because there are three more boys wearing glasses.
Girls = x
Boys = x + 3
Total = 5
<u>Calculate:</u>
x + x + 3 =5
2x + 3 =5
2x = 2
x = 1
Boys wearing glasses = (1) + 3 = 4
Girls wearing glasses = 1

If you could give a sample question I think it would be easier to explain
72 chicken and 4ó3 dogs come to 535 animals altogether.
For 45, 45, 90 angled triangles, the two legs are equal to 'x', and the hypotenuse is equal to
. Since we know the length of the hypotenuse, we can set this equal to it:
Divide the square root of 2 to both sides:
So the length of both AC and BC is approximately 5.657.
