Okay so you don’t give numbers but I can tell you how to solve (where to put your numbers.
The way to solve is simply to take B and subtract that from A and the product of that is how far he has driven in set minutes.

Example- 1100(B)-900(A)=200(Amount of miles on set minutes.)

When you learned to add decimals, you saw that lining up the decimal point in the addends is really important. Why do you think it is not necessary to line up the decimal points in the two factors when multiplying decimals?

Answer in 2 complete sentences.

It is not necessary to line up decimals while multiplying because you count the decimals instead of bringing them down. Plus lining up decimals while adding can overcomplicate the problem with too many zeros.

Anitha and Jyothi shared some money. Anitha had $4x and Jyothi had $(2x + 8).
Both of them had $56 altogether. Find the value of x and hence find out how much
did Jyothi get?

Answers

Answer:

$24

Step-by-step explanation:

To begin we need to form an equation that equals the total amount of money, which is 56. The question tells us that Anitha's money and Jyothi's money comes to a sum of $56 (the total amount). So, in our equation we will be doing Anitha + Jyothi = 56; our equation will be 4x+2x+8=56.

The next step is to rearrange the equation to get x=..., and we can do this using the funnel method like I have shown in the attached image. First, I simplified to get 6x+8=56. Then, I subtracted 8 from both sides to get 6x=48. Finally, I divided by 6 on both sides to get x=8. This is the first step of the question completed.

The finish the question, we need to work out Jyothi's total money, and since we now know x=8, all we need to do is substitute 8 where x is for Jyothi. So, we need to calculate the answer to 2*8+8, and following the rules of BIDMAS, we get 24. Which is the final answer.

ATQ
4x + 2x + 8 = 56
6x + 8 = 56
6x = 56- 8
6x= 48
x = 48/6
x = 8

Jyothi = 2x + 8 = 2 x 8+8= $24

Using this, we get 6^-3 x -1 or,

6^3

For the second one we get (6)^-3 x 3 or,

I am guessing that the last 2 are fractions. (1/6)^-3 is equal to 216 which is 6^3.

For the last one, (1/6)^3 is basically the opposite so the answer is 6^-3.

Which statement about the solving process when an equation has no solution or infinite solutions is TRUE?
The variable will always end up on the left-hand side of the equation.
The constant terms will always be a multiple of 3.
Collecting the like terms will result in the elimination of the variable.
Gathering the like constant terms will always result in the value 0.

Answers

Answer:

A

Step-by-step explanation:

The variable will always end up on the left-hand side of the equation

The statement that is true about the solving process when an equation has no solution or infinite solutions is: “The variable will always end up on the left-hand side of the equation.” Hence, Option A is correct.

What are infinite solutions?

Both sides are equivalent in an endless solution. For instance, 12x + 4y - 16 = 6x + 2y - 8 Using a formula or method for infinite solutions, one can simplify the equation and make both sides equal to one another, making it an infinite solution. Infinity is a symbol for boundlessness or infinity. The sign "" is typically used to denote it.

When the lines are parallel and they share the same y-intercept, the system of equations has an infinite number of solutions. If the slope and y-intercept of two lines match, they are in fact the exact same line. The variable, which always appears on the left side of the equation, has infinite solutions.

Therefore, Option A is correct.
