Answer:

It's the second option

Step-by-step explanation:

the answer should be 233 but he got 243 because he forgot to regroup

Answer: Grant did not regroup the 4 tens when he subtracted 7.

Everything else he did was correct! When got down to the bottom he made a mistake.

Because there was a zero, grant should have token away from the 4 in which it would become a 3 and given to the 0 so it would become a 1. Due to the fact that he did not do this he got it wrong.

Hope this helps:)

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

Or

91 - n

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.

Answer: x=6

Step-by-step explanation:

Those two angles are supplementary, so added together, they will equal 180.

That being said,

23x+3+6x+3=180

29x=174

x=6

is the equation. By solving that, you get

x=6

In the Central City Grand Prix, out of 30 cars that started the race, 12 of them finished.

PART A: What percent of the cars finished the race?
PART B: What percent did not finish the race?

Explain fully for brainliest

Answers

Answer:

a) 60% finished the race    b) 40% did not

Step-by-step explanation:

if this is useful please make me brainliest

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.

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.

From the first edition in 1812/1815 to the final one in 1857, the Grimms received numerous versions of tales already in their collection and new tales from strangers, friends, and colleagues, and they often decided to replace one tale with another version, to delete some of the tales, or to include variants in their footnotes.For what purpose does the author mention the names of various Grimm works in this excerpt?
