First, you must find the tip. Multiply 55.50 by 0.2 (the decimal form of 20%). 55.50*.2=11.10. Next, find the sales tax. You don't pay tip on tax as the hint declares, but you also don't pay tax on the tip. Therefore, you must find 7% of 55.50 by multiplying 55.50 by 0.07 (the decimal form of 7%). 55.50*.07=3.885. You don't want to round until the very end, so we leave that in full form for now. Finally, add all your expenses: 55.50+11.10+3.885=70.485. Now to figure out how much each person will pay. There are six people paying, so 70.485/6= 11.7475. Finally, round to the nearest hundredth, otherwise known as the nearest cent, to get the answer of $11.75, or C.

solve the equations below. make sure you say how many solutions each equation has(MCC.8.EE.7a) A. 5p-9=7p-19 b. 5p-9= 5p-19 C. 5
Sedaia [141]
<h3>Answer:</h3>
  • A) p = 5, one solution
  • B) no solutions
  • C) infinite solutions
<h3>Step-by-step explanation:</h3>

A) Add 19-5p to each side of the equation:

... 10 = 2p

... 5 = p . . . . . divide by the coefficient of p

B) Subtract 5p from both sides of the equation:

... -9 = -19 . . . . . there is <em>no value of p</em> that will make this true. (No solution.)

C) Subtract 5p from both sides of the equation:

... -9 = -9 . . . . . this is true for <em>every value of p</em>. (Infinite solutions.)

Westkost [7]

Answer: The best estimate for the amount of money she saves to buy clothes = $ 562.5

A prism is completely filled with 96 cubes that have edge length of 1/2 cm.
ch4aika [34]
I know this is kinda late, but...

You can solve this easily as long as you remember how to find the volume of a cube. v=a^3, when a means length. The length is 1/2 cm, or .5 cm.
 So, v+.5^3, which equals .125 cm. Each cube has a that volume. Now, multiply that by how many actual cubes there are, 96.

96 * .125 = 12
