S + g = 425
g = s + 25
-----------------
We will use the method of substitution:
s + s + 25 = 425
2 s = 425 - 25
2 s = 400
s = 400 : 2
s = $425
g = 200 + 25
g = $225
Answer: Seiji earned $200 and Gavin earned $225.

Tony worked 4 2/3 hours on his science project. Sonia worked 1 1/4 times as long on her science project as Tony did.For how many
kherson [118]
To find how many hours Sonia work on her science project,we can multiply the working hours of Tony by the times Sonia did:

4 \frac{2}{3}  \times 1 \frac{1}{4}  \\  =  \frac{14}{3}  \times  \frac{5}{4}  \\  =  \frac{70}{12}  \\  = 5 \frac{10}{12}  \\  = 5 \frac{5}{6}
Therefore Sonia work on her science project for 5 5/6 hours.

Hope it helps!

HELP PLEASE!
wel

Answers:

\text{Perimeter} = 14\sqrt{5}\\\\\text{Area} = 50\\\\

=======================================================

Work Shown:

L = 2\sqrt{5} = \text{length}

W = 5\sqrt{5} = \text{width}

P = perimeter

P = 2*(L+W)\\\\P = 2*(2\sqrt{5}+5\sqrt{5})\\\\P = 2*(7\sqrt{5})\\\\P = 14\sqrt{5}\\\\

-------------

A = area

A = L*W\\\\A = (2\sqrt{5})*(5\sqrt{5})\\\\A = (2*5)(\sqrt{5}*\sqrt{5})\\\\A = 10\sqrt{5*5}\\\\A = 10\sqrt{25}\\\\A = 10*5\\\\A = 50\\\\

3000 is 32% of what number?
qwelly [4]

   We have, 32% × x = 3000

   or, 32100 × x = 3000

   Multiplying both sides by 100 and dividing both sides by 32,

   we have x = 3000 × 10032

   x = 9375

   If you are using a calculator, simply enter 3000×100÷32, which will give you the answer.
