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 1

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 2

Answer:

63 coins are not nickels.

Equation to find n:

91 - 63

Or

91 - n

(Is this right I don't know, I'm trusting my hands right now)

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.

Step-by-step explanation:

60 fin 40 didnot

**Explanation:** Most of the time, people use percentages to express a fraction or a portion of a whole. In fact, percent literally means "per 100" or "out of 100." So when you see 25 percent, for example, you could read it as "25 out of 100" or "25 per 100 parts." But you can also have percentages that are greater than 100 percent – and when that happens, there's at least one complete whole, or a whole number, hidden in there somewhere.

Step-by-step explanation:

Kip bought [tex]1\frac{4}{6}[/tex] pounds of toffee. He gave [tex]\frac{5}{6}[/tex] of a pound to his friend. How much toffee does he have left?

The narrator is asking how much he has left after giving some toffee to his friend, that means we have to subtract.

[tex]1\frac{4}{6}[/tex] - [tex]\frac{5}{6}[/tex]

We already have an equal denominator so we can just subtract.

[tex]\frac{10}{6}-\frac{5}{6}[/tex] = [tex]\frac{5}{6}[/tex]

Kip has [tex]\frac{5}{6}[/tex] pounds left.

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.
