A + B = C, then C - A = ?

In 9.c. you name the sequence arithmetic, yet it appears to be geometric, r = 1/2.   9.3. Using the GS 2log x, log x, (log x) / 2, (log x) / 4,... r = 1/2 S12 = (0.5)(2log x) / (1 - 0.5)     Given S12 = (0.5)(2log x) / 0.5 S12 = 2log x     ...

y = 3900(1 + 0.0325)t

i = p · r · t            (Learn it!) i = 750(0.02)(7)   Can you calculate and answer?

10000 = 3500(1.12)t 2.85714 ≈ 1.12t ln 2.85714 ≈ t ln 1.12   Can you solve for t and answer?

Baking soda, sodium bicarbonate, is used as a leavening agent.

1 person needs 12 days to make 48 chairs (288/6) 1 person makes 4 chairs a day   (48/12) 4 persons make 16 chairs a day  (4*4) 108 chairs @ 16 chars per day = 6.75 days

That is because the magnetic pole at the north geographic pole is the south magnetic pole of the earth. Just has to be!

y = x - 2 -5 = 2 - 2      is that true?

One clerk needs four hours to process a folder. Now how many hours does that one clerk need to do 8?

Draw and label a diagram! tan θ = 7/2   Use a table or a calculate to determine the value of θ.

z = (X - μ) / σ     (Learn that!) z = (99.5 - 98.20) / 0.62   Can you calculate and answer?

The unit rate would be 1 3/7 ÷ 2/3 10/7 ÷ 2/3 10/7 · 3/2     divide by fraction, invert and multiply 15/7    Charlies reads 15/7, or 2 1/7, page per minute.

i = p · r · t     (Learn that!) i = (800)(0.05)(3)   Can you calculate and answer?

Well we could just "crunch"the numbers: 92 - 29 = ? 83 - 38 = ? 72 - 27 = ?

2x+2 - 2x = 48 2x(22 - 1) = 48 2x(3) = 48 2x = 16 2x = 24 x = 4

xy = 36 x + y = 18   y = 36/x x + 36/x = 18 x2 + 36 = 18x x2 - 18x + 36 = 0   Use the Quadratic Formula (Hint the solutions are irrational!)

37 ≤ 22 + t
