Step-by-step explanation:
Since this is a rectangle these two equations for the length have to equal each other.
2x+4=7x-1
We now need to get all of the x's on one side and constant numbers on the other side.
add 1 to both sides and subtract 2x from both sides.
5=5x
divide 5 from both sides.
x=1
This is how we solved and make the equation.
Stock A = 100
Stock B = 45
For the past months, his stocks inversely decreased.
Stock A = m cents / share
Stock B = n cents * share
So the equation is
= 100 (0.01m) + 45 (0.01n)
<span>= m + 0.45n</span>
15n+21
We dont know how much square peter buys and per square cost 15$. So thats mean peter buys 15n$
And the total delivery charge 21$
Its cost 15n+21
I think the answer is either c or d
Amy's current age is 16 years greater than Peter's age, so Amy's current age is equal to x + 16.
6 years ago, Amy's age was equal to twice that of Peter's age at that point, so her age was 2(x - 6).
As currently her age is x + 16 then 6 years ago her age was x + 16 - 6, which is x + 10.
As 6 years ago her age was equal to 2(x - 6) and x + 10, we can see that x + 10 = 2(x - 6).
