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

Answers

Answer:

51414

Step-by-step explanation:

1000+2000 = 3000

3000+4000 = 7000

5000+600+70 = 5670

3000 + 5670 = 8670

8670 + 7000 = 15,670

80+9+69+12+35,574= 35744

35744 + 15,670 = 51414

Answer:

1000+2000+3000+4000+5000+600+70+80+9+69+12+35,574= 51,414

The rabbit population in a certain area is 500% of last​ year's population. There are 1,300 rabbits this year. How many were there last​ year?

Answers

There were 260 rabbits last year.

We know that last year was the original population as 100%. The population is now 5 times higher, as 100% x 5 is 500%.

To find the original rabbit population, we would then divide this years population of 1300 by 5, to get 1/5 aka 100% of the population. This number is 260

500/100=5
1300/5=260
260 rabbits hope this helps

Make an equation that has the numbers : -3.78 , -1.2y, and -4.2y

Answers

Answer: In solution

Step-by-step explanation:

Well, first you need to arrange the numbers in anyway, separated by operations. I just did:

-3.78 + (-1.2y + -4.2y)

We then need to come up with the other side of the equation.

For this, I added the like terms:

-3.78 + (-1.2y + -4.2y) = -3.78 -5.4y

Then, I came up with a value for y. Y = 5

Then, I multiplied -5.4 by 5, getting -27 so,

-3.78 + (-1.2y + -4.2y) = -3.78 - 27

Again, I collected like terms:

-3.78 + (-1.2y + -4.2y) = -30.78

Now, I have my equation.

———————————————————————————————

HOW TO SOLVE THE EQUATION

-3.78 + (-1.2y + -4.2y) = -30.78

1. Add 3.78 to both sides

-1.2y + -4.2y = -27

2. Collect like terms

-5.4y = -27

3. Divide both side by -5.4

y = 5

Answer:-

-3.75 + -1.2y = -4.2y

Step-by-step explanation:

the answer would then be that y= 1.26 when solved

What is the LCD of 8/21 and 2/7?

Answers

Answer:

21

Step-by-step explanation:

7 can go into 21

Answer:

21

Step-by-step explanation:

Equivalent Fractions with the LCD

8/21 = 8/21

2/7 = 6/21

Solution:

Rewriting input as fractions if necessary:

8/21, 2/7

For the denominators (21, 7) the least common multiple (LCM) is 21.

LCM(21, 7)

Therefore, the least common denominator (LCD) is 21.

Calculations to rewrite the original inputs as equivalent fractions with the LCD:

8/21 = 8/21 × 1/1 = 8/21

2/7 = 2/7 × 3/3 = 6/21
