Answer:
m= 4.8 months
Step-by-step explanation:
by taking x as the money the International Business Club has at any time of the year,250.5 for their initial money, 35 as the money they spend every month and m being the month that have passed since the beginning of the school year; it all can be related to the following equation:
x= 250.5 - (35*m)
And doing the same thing with the money from the Future Agricultural Leaders Club, associating their money to the variable y, the equation would be:
y=300 - (45.25*m)
as it is wanted to know at what month does both clubs have the same amount of money, x and y, must be the same, so:
250.5 - (35*m) =300 - (45.25*m)
this equation can be solved by putting both terms that are related to m on the same side of the equality, and those who aren’t related on the other side:
(45.25*m) - (35*m)= 300 -250.5
then, on the first side of the equation, m can be taken out as common factor:
(45.35-35)*m=49,5
and solving for m:
m=
m=4.8
H = V/B

The base of the prism is given by the expression 2X^2+8x-9
then c)5x+3
You can subtract 4x from each side of the equation.
Then you'll have the variable only on one side.
Before: 5x - 7 = 4x - 1
After: x - 7 = - 1
Now it's a lot easier to solve.
========================================
I just noticed that you're giving 10 points for this one.
That's a bunch, so I guess I owe you some more ...
I really ought to go ahead and finish the solution:
Original equation: 5x - 7 = 4x - 1
Subtract 4x from each side: x - 7 = - 1
Add 7 to each side: x = 6
(Once you subtracted 4x from each side,
there really wasn't much more left to do.)
Answer:
