Answer:
54
Step-by-step explanation:
2x+2=3x-52
subtract 2 from both sides
2x=3x-54
x=54
A common denominator is when 2 fractions have the same denominator and a common multiple is when two multiples have at least 1 number alike
Example: Common Denominator
4/10 6/10
Example: Common Multiple
2: 2,4,6,8,10,12
4: 4,8,12
Answer:
the length is 22 and the width is 18
Step-by-step explanation:
The perimeter is 2(l) + w(2)
w is the width and l is the length
if you plug in 22 and 18 you get
2(22)+(2)18
then you do multiplication to get
44+36
then you add and you get 80
(2x-3)(x+5)
Use foil to simplify, First multiply together the first terms of the pairs, then the outer terms, the middle terms, and finally the last terms. Then combine like terms.
2x^2+10x-3x-15 equals 2x^2+7x-15
Its decreased by 200 in the 4 years from 1994 to 1998 That is 50 less per year
In 1990 the population would have been 2500
So the required formula is
P = -50t + 2500 ( or you could write it as P = 2500 - 50t
