For the subtracting fractions, I would just make them into improper fractions (examples: 6/4, 5/3). To do that, you multiply whole number by the numerator (number on top of fraction), then add the denominator (number at the bottom), and finally, leaving the denominator as is.
Then make them have the same denominator. you might have to multiply or divide in order to match the denominators. then you may add or subtract straight across. NEVER change the denominator.
note: you might be required to make the improper fractions into mixed (ex: 4 1/2)
With multiplying, just multiply across (numerator × numerator, and denominator × denominator)
Answer:
The answer to your question is: both lines are the same.
Step-by-step explanation:
3x + 3y = 10
-9x -9y = -30
Elimination method
9x + 9x = 30
-9x - 9y = -30
0 0 0
The answer will be that out of 36 boys 24 speak french and 12 speak german and out of 24 girls 16 speak french and 8 speak german.
<h3>What is the frequency tree?</h3>
In the question we have that there are 60 students in total out of which 36 are boys:
So number of the girls will be = 60-36=24
Now if 2/3 of the boys speak french the number of the boys who speak french will be = (2÷3)x36=24
Now the number of the boys who speak german will be =36-24=12
Now since 40 students study french so we have the number of the boys who speak french is 24. so the number if the girls who speak french will be =40-24=16
Since there are 24 girls in total and out of them 16 speak french so the remaining girls speak german=24-16=8
Hence answer will be that out of 36 boys 24 speak french and 12 speak german and out of 24 girls 16 speak french and 8 speak german.

Answer:
7.211103
Step-by-step explanation:
For:
(X1, Y1) = (-3, 4)
(X2, Y2) = (1, -2)
Distance Equation Solution:
d=(1−(−3))2+(−2−4)2−−−−−−−−−−−−−−−−−−−√
d=(4)2+(−6)2−−−−−−−−−−√
d=16+36−−−−−−√
d=5–√2
d=7.211103
:)
P+2-4=14
p-2=14
add 2
p+2-2=14+2
p+0=16
p=16
