Find a common denominator

5 1/4 - (-3.55) + (-3 2/5)

Answers

Answer:

Step-by-step explanation:

Conversion a mixed number 3 2/

5

to a improper fraction: 3 2/5 = 3 2/

5

= 3 · 5 + 2/

5

= 15 + 2/

To find a new numerator:

a) Multiply the whole number 3 by the denominator 5. Whole number 3 equally 3 * 5/

5

= 15/

5

b) Add the answer from previous step 15 to the numerator 2. New numerator is 15 + 2 = 17

c) Write a previous answer (new numerator 17) over the denominator 5.

To find a new numerator:

a) Multiply the whole number 5 by the denominator 4. Whole number 5 equally 5 * 4/

b) Add the answer from previous step 20 to the numerator 1. New numerator is 20 + 1 = 21

It is suitable to adjust both fractions to a common (equal, identical) denominator for adding, subtracting, and comparing fractions. The common denominator you can calculate as the least common multiple of both denominators - LCM(5, 4) = 20. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 5 × 4 = 20. In the following intermediate step, it cannot further simplify the fraction result by canceling.

In other words - seventeen fifths plus twenty-one quarters is one hundred seventy-three twentieths.

32 people will each drink a glass of lemonade. It takes 6 lemons to make one glass. If lemons are sold in bags of 10, how many bags should he buy?

Answers

Answer:

20 bags

Step-by-step explanation:

they should by 20 bags because 6 x 32 will equal how many lemons total you need. then you divide that number by 10.

Answer:

He should buy 20 bags of lemons.

Step-by-step explanation:

Okay, so the first step will be to see how many lemons we first need. We do this by multiplying the 32 people and the 6 lemons:

32 x 6 = 192 lemons

The next step is to find out how many bags we need. So, we know we have 192 lemons and each bag of lemons contain 10, so we need to divide 192 by 10.

192 divided by 10 = 19.2

Now, 19.2 isn't the answer because it is not a whole number. We can't buy a fraction of lemons. So, we need to buy 1 more extra bag to be able to have all 32 people be able to have some lemonade:

19 + 1 = 20 bags of lemons.

Jin’s mother estimates there is a half gallon of fruit punch remaining in the container. There is actually 72 ounces of fruit punch in the container. What is the percent error of Jin’s mother’s estimate, rounded to the nearest tenth?

PLS I NEED HELP ITS DUE IN 10 MINUTES!!!!!!

Answers

Answer: 0.7 I think

Step-by-step explanation:

The percent of error of Jin's mother's estimate is 4,9% (4,9 percent)

The Percent of error of Jin's mother's estimate can be calculated as follows ?

The first step is to convert a half gallon to ounces

1 gallon = 153,722 ounces

= [tex]\frac{1}{2}[/tex] × 153,722

= 76,861 ounces

The next step is calculate the error between Jin's mother's estimate (76,861 ounces) and the actual amount of fruit punch in the container (72 ounces)

The error = 76,861 - 72

= 4,861

Third step is to round the calculated the percent error to the nearest tenth.

4,861 ÷ 100 = 4,861%

The final step is to round it to the nearest tenth by round the second digit behind the coma which has value more than 5 to the higher number of the first digit behind the coma.

4,861% = 4,9%

Hence, the percent error of Jin's mother's estimate is 4,9% (4,9 percent)

Which set of points could represent one of the side lengths of a square that is congruent to the one shown on the coordinate plane?

Answers

The set of points that represent one side of the given square is (C) (−2, −2) and (−8, −2).

What are squares?A square is a regular quadrilateral in Euclidean geometry, which means that it has four equal sides and four equal angles. It can alternatively be explained as a rectangle with two neighboring sides that are of equal length.The square's angles are at a straight angle or 90 degrees. The square's diagonals are also equal and split at a 90-degree angle.

So, in the given figure of the square on the graph:

Let, us first label line AB.Now, count the coordinates of points A and B.

We can easily tell that the coordinates are:

A: (-2, -2)B: (-8, -2)

Therefore, the set of points that represent one side of the given square is (C) (−2, −2) and (−8, −2).

A track team needed to run or jog 20 laps for their practice. Of the total 20 laps, Sara completed 45, Jamie completed 58, Keenan completed 59, Maya completed 0.833, and Trey completed 0.875. Identify the descending numeric order of the laps completed.

Answers

Answer:

The descending numeric order of the laps was completed as 59, 58, 45, 0.875,0.833

What is descending order?

Descending order is defined as when numbers (or other items) are arranged from the largest numbers to the least numbers, it is said to be in descending order.

Sara finished 45 laps, Jamie completed 58, Keenan completed 59, Maya completed 0.833, and Trey completed 0.875.

We have the given numbers as:

45, 58, 59, 0.833, 0.875

we have to determine the descending order of given numbers

Here the largest numbers to the least numbers, it is said to be in descending order.

⇒ 59  > 58  > 45  > 0.875 > 0.833

Hence, the descending numeric order of the laps completed:

Keenan completed 59 laps

Jamie completed 58 laps

Sara completed 45 laps

Trey completed 0.875 laps

Maya completed 0.833 laps

The answer to the problem is (-3, -6)

Answer:

  (x, y) = (-3, -6)

Step-by-step explanation:

You want the solution to the system of equations 6 = -4x +y, -5x -y = -21 using the substitution method.

Expression for y

Adding 4x to the first equation gives an expression for y:

  6 +4x = y

Substitution

This can be substituted into the second equation:

  -5x -(6 +4x) = 21

  -9x -6 = 21 . . . . . simplify

  -9x = 27 . . . . . . . add 6

  x = -3 . . . . . . . . . divide by -9

  6 +4(-3) = y . . . . . . . find y using the expression for y

  6 -12 = -6 = y

The solution is (x, y) = (-3, -6).

Sorry for over complicating it

Using simple mathematical operations, the value of TEST is 20,51,920.

What are mathematical operations?Calculating a value using operands and a math operator is referred to as performing a mathematical "operation." The math operator's symbol has predetermined rules that must be applied to the supplied operands or numbers.A rule that specifies the right procedure to follow while evaluating a mathematical equation is known as the order of operations. Parentheses, Exponents, Multiplication, Division (from Left to Right), Addition, and Subtraction are the steps that we can remember in that order using PEMDAS (from left to right).

So, the value of the TEST will be:

The letter stands for the same digit everywhere it appears.We have, HE + SET + THE = TEST.

Then,

H = 8, E = 5 ⇒ HE = 85S = 19, E = 5, T = 20 ⇒ SET = 19520T = 20, H = 8, E = 5 ⇒ THE = 2085

Now,

85 + 19520 + 2085 = TEST20,51,920 = TEST

Therefore, using simple mathematical operations, the value of TEST is 20,51,920.
