4: Solve the equation for x: 3x - 6y = 12
2y - 4
(12 - 6y)/3
2y + 4/3
(6y + 12)/3


5: Solve the equation for L: P = 2w + 2L
P - 2w
P/(2 - w)
w - (P/2)
(P - 2w)/2


6: The sum of two numbers is 3 times their difference. If the larger number is 6 more than the smaller number, what is the larger number?
Hint: "sum" means the addition of numbers; "difference" means subtraction. So, set up an equation, using words: larger + smaller = 3(larger - smaller)
then substitute in expressions for the larger and the smaller (created from facts in the problem) to solve. Be sure to answer for the larger number at the end!

15: Kim and Deb ride bicycles in opposite directions. Deb's speed is three miles per hour faster than Kim. If they are 16.5 miles apart in 1.5 hours, what is the speed of Kim?






4 mph
5 mph
7 mph
9 mph

Answer 1

I only have time to help with the first 7 right now.
Sorry! Will come back later and do the rest.
1. Average speed = total distance/total time.
So v = s/t
5 = 75/t
t = 75/5 = 15 hours.

2. The total balance, S = P + Prt,
where P is the principal, r is the interest rate
and t is the time in years.
By the distributive property, S = P(1+rt),
so
P = S/(1+rt) = 300/(1 +.05*5) = 240.
Check: 240(1+ .05*5) = 300.

3. You earned $60 in interest = 300 - 240.
Problem 2 is called a present value problem
in mathematics of finance.

4. Add 6y to both sides to get
3x = 6y+12
Now divide by 3:
x = (6y+12)/3

5. P = 2w + 2L
Subtract 2w from each side:
2L = P-2w
Divide by 2:
L = (P-2w)/2.

6. Let L be the larger number and S the smaller.
Then L + S = 3(L-S).
But L = S+6. In other words, we must add 6
to the smaller number to get the larger.
So S = L-6
and
L +(L-6) = 3(L -L+6) = 18
2L = 24
L = 12.
The larger number is 12.

7. The smaller number is 12-6 = 6.

I'm surprised you don't have a text or tutor for
this type of work. Couldn't you or your
parents borrow a book from your local high school,
or find a text online?
Good luck!
