So you divide 50 by 2 so there are 25 before him
Answer:
22x - 14
Step-by-step explanation:
pretty sure its like this..
3(4x-3)+5(2x-1)
= 3×4x + 3×(-3) + 5×2x + 5×(-1)
= 12x + (-9) + 10x + (-5)
and according to the rules of multiplying negative by positive...
= 12x - 9 + 10x - 5
combine like terms using the symbols on its left
= 12x + 10x - 9 - 5
= 22x - 14
Answer:
FG = 15
Step-by-step explanation:
Note that
EF + FG = EG ← substitute values into equation, that is
6 + FG = 21 ( subtract 6 from both sides )
FG = 21 - 6 = 15
Step-by-step explanation:
(a/b) + (c/d)
Find the common denominator. In this case, bd. So multiply the first fraction by d/d, and the second fraction by b/b.
(ad)/(bd) + (bc)/(bd)
Add the fractions.
(ad + bc) / (bd)
Answer:
B) 0.42
Step-by-step explanation:
population density=number of people/square units
we plug in 2,100 for the first one but we don't know the second one for that we need the area which is A=π
so the radius is 40 millimeters so 
=1600 1600*π=5024
2,100/5024=0.417 round it up and it is 0.42
so B) 0.42 is the answer
