PLEASE MAKE SURE HELP ME!

Answers

Answer:

1. The first problem is wrong, it should be 0.5(3(15) + 2(20)) because the parentheses make sure that every purchased item is being divided by 2 (multiplying by 0.5 is the same as dividing by 2)

2. The second problem is partially correct. The first two answers you have checked are correct, but the last one is wrong. The third answer should be 6 + 12 instead because that's just a simplified version of 2(3) + 6(2), meaning they are equal

3. I cannot read your answers in the "Why or Why Not" column in the third problem, but the answers you gave in the "Evaluate" and "Does It Work?" columns are all correct.

Divide 14% by 60ml
* EX. How to calculate percentage of a number. Use the percentage formula: P% * X = Y
Convert the problem to an equation using the percentage formula: P% * X = Y.
P is 10%, X is 150, so the equation is 10% * 150 = Y.
Convert 10% to a decimal by removing the percent sign and dividing by 100: 10/100 = 0.10.*
You get 8.4ml

Explain step by step how to do 10.25 x .15.

Answers

Answer:

1.5375

Step-by-step explanation:

Multiply without the decimal points, then put the decimal point in the final answer

1025 x 15 = 15375

....

10.25 has TWO decimal places

0.15 has TWO decimal places

Therefore, when you multiply with the decimal points (10.25 x 0.15), the answer should have FOUR total decimal places.

So the answer is 1.5375

Yes that is the answer

A jar contains only pennies, nickels, dimes, and quarters. There are 29 pennies, 13 dimes, and 21 quarters. The rest of the coins are nickels. There are 91 coins in all. How many of the coins are not nickels? If n represents the number of nickels in the jar, what equation could you use to find n?

Answers

Answer:

First Question: 63 coins are not nickels.

Second Question: 63+n=91

Step-by-step explanation:

For your first question: 29+21=50 and 50+13=63. 63 coins are not nickels.

For your second question: You can do 29+21+13+n=91, I just simplified and said 63+n=91. You can choose.

Hope that this helps! Good luck with what you're working on!

Answer:

63 coins are not nickels.

Equation to find n:

91 - 63

91 - n
