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:)

If 3/4 = x/18 , then x is equal to

Answers

Answer: x = 13.5

3/4 = x/18

⇔ x = 3/4 .18 = 27/2 = 13.5

Step-by-step explanation:

Answer:x = 27/2

Step-by-step explanation:

Step 1: Cross-multiply

3/4=x/18

(3)*(18)=x*(4)

54=4x

Step 2: Flip the equation.4x=54

Step 3: Divide both sides by 4x/4=54/4x

= 27/2

To convert larger units to smaller units mulitply when the units are smaller you need more pf them to express the same measure. To convert smaller units to larger units, divide. When the units are larger, you need fewer of them to express the same measure.

Answer:

To convert greater units to smaller units you mulitply. When the units are smaller you need more to express the same measure. When you have to  convert smaller units to larger units, divide. When the units are bigger, you need less of them to be the same measure.

Answer: 42

Step-by-step explanation:

If x-y=6 and x^2+y^2=24, find x^3-y^3.

Answers

Answer:

162.06

Step-by-step explanation:

sorry i'm not the best an explaining but i'm confident in my answer.

the first thing to do is get rid of the ² in x²+y²=24, we do this by √24 which ≅4.90 (i rounded to the hundreth place)

then we have this

x-y=6

x+y=4.90

I am using the elmination method. To do that you need to get two letters to have the same coefficient (in 4x 4 is the coefficient) with oposite signs (one possitive one negitive)

In our equation here we see that the same coefficient is 0, and there is oposite signs for y. Therefore we can add the two equations and get

2x=10.9 (the y cancels out)

now we have a simple equation and all that is left is to solve it

10.9/2=5.45

x=5.45

Now we need to find y we do that by pluging the x value into one of the equations I choose the first one becasue its easiest.

(5.45)-y=6  

y= - .55

now that we have both x and y plug them into the final equation (5.45)³-(-.55)³= 161.89-(-.17) =162.06

Therefore x³-y³≅162.06!

c is the correct one

Answer:

Probably C

Step-by-step explanation:

Repeating Decimal: a decimal where a number or a pattern of numbers repeats forever

For example, 0.2222... or 0.671671....  (The "..." means that it repeats like that forever)

A. 3/7=  0.142857142857142857... (6 repeating digits)  This is a repeating decimal because the last six digits continue forever

B. 3/4=0.75. This number is not a repeating decimal because a repeating decimal goes on forever, while this only has two decimal places.

C. 1/9= 0.11111... This is a repeating decimal because it goes on forever and has a pattern (all are 1s)

D. 5/11=0.454545... This is also a repeating decimal because the last two digits repeat forever.

There is probably something wrong with the question (or your unit) because three of these numbers are, in fact, repeating decimals. If I were you, I would ask your teacher (it gets you respect from the teacher=more chance that they'll be lenient with you)

But if you really don't want to, I would go with "C" because it only has one repeating decimal place, and your curriculum probably says that a repeating decimal is only one digit.

Good Luck! :)
