Step-by-step explanation:
Ratios can be written as:
a to b
a:b
a/b
We want to find boys to girls, and there are 24 boys and 12 girls. So, we can write it as
24 to 12
24:12
24:2
All of these can be reduced, since both the numerator and denominator can be divided by 12.
Numerator: 24/12=2
Denominator: 12/12=1
2 to 1
2:1
2/1
Step-by-step explanation:
for the 2 lines to be parallel the angles of crossing the third line must be equal.
and it is a given for 2 crossing lines, that the right top angle is equal to the left bottom angle, and the left top angle is equal to the right bottom angle.
therefore, the 2 indicated angles must be equal :
3x + 48 = 6x
48 = 3x
x = 16
Answer:
im gonna guess that the problem is 2x+13-9y, the answer is 38
