I qould say the answer is b. 59.
Fractions need common denominator to add or subtract them because without denominators a fraction is not a fraction, it is a whole number
Example - 2/8 is a fraction
but 2 is not a fraction
F=m+25
m+f=139, using f from above we have:
m+(m+25)=139
2m+25=139
2m=114
m=57, and since f=m+25
f=82
So there are 57 males and 82 females.
Answer:
x=64
Step-by-step explanation:
the shapes are similar
since the difference between 20 and 24 is 4
then you add 4 to 60 and get 64
I don't actually know 100% that this is correct but it makes sense in my head
b = - 4
slope m = (0 + 4)/(4 - 0) = 4/4 = 1
equation
y = x - 4
