Answer:
x = 15
Step-by-step explanation:
Cameron started with 20 pieces of gum and gave away x number of pieces.
Cameron = 20 - x
Connor started with 35 pieces of gum and gave away twice as many as Cameron did.
Connor = 35 - 2x
Equate both Cameron and Connor expression
20 - x = 35 - 2x
Collect like terms
20 - 35 = -2x + x
-15 = -x
Divide both sides by -1
15 = x
x = 15
Check:
Cameron = 20 - x
= 20 - 15
= 5
Connor = 35 - 2x
= 35 - 2(15)
= 35 - 30
= 5
Answer:
False
Step-by-step explanation:
It is given that Noah thinks :
9x - 2x + 4x = 3x as the subtraction sign after 9x tells us to subtract everything that comes after 9x.
This is wrong as according to the BODMAS rule, we have to do the addition operation first and then followed by subtraction operation.
That is
⇒ 9x - 2x + 4x
⇒ (9x -2x)+ 4x
⇒ 7x + 4x
⇒ 11x
Therefore the answer to the equation is 11x and not 3x.

Since represents the number of years passed since 2005, in 2005 we have , and in 2015 we have . Let represent the profits of Jones and Davis, respectively, at year y.
We have
Choosing the best company somehow depends on how much time you can wait: Jones start with a higher value (10 vs 8), but it has a descending trend, because the multiplicative factor goes to zero as t grows.
On the other hand, Davis starts with a smaller value, but tends to infinity as t grows.
So, if you need an immediate result, the most valuable company is Jones, otherwise you're certain can Davis will eventually become bigger.
More precisely, we have
So, after 11 years, Davis will overcome Jones.
