Answer:
195
Step-by-step explanation:
If there are x boys, then there are x+26 girls. Hence, we write the equation,
x+(x+26)=364
Solve for x:
2x+26=364
2x-338
x=169
So there are 169+26 =195 girls
9514 1404 393
Answer:
18
Step-by-step explanation:
The least common denominator (LCD) is the least common multiple (LCM) of the denominators.
Here, the denominators are ...
9 = 3·3
6 = 3·2
So, their LCM is 3·3·2 = 18.
The least common denominator of the given fractions is 18.
__
7/9 = 14/18
11/6 = 33/18
If you were to replace the x's with 2, your equation would turn into:
(2)^2-4(2)+5
From there, you'd just solve.
4-8+5=1
Your answer would be 1.
