The value of the variables based on the equation is illustrated below.

<h3>How to calculate the variables?</h3>

Based on the information given, it should be noted that an equation simply means a formula that can be used to express the equality of two expressions.

1x - 1 - 4.2x = 5.3

Collect the like terms

1x - 4.2x = 5.3 + 1

-3.2x = 6.3

x = -1.969

7/8m - 4/7 - 5/6m = - 3/4

Collect the like terms

0.875m - 0.5714 - 0.833 = -0.75

0.875m = -0.75 + 0.5714 + 0.833

0.875m = 0.6544

m = 0.6544/0.875

m = 0.748

4.3v + 10.75 - 4v = 8.11

Collect the like terms

4.3v - 4v = 8.11 - 10.75

0.3v = -2.64

v = -2.64/0.3

v = -8.8

9/7 + 9/7x - 6/7x = 0

Collect the like terms

9/7x - 6/7x = 0 - 9/7

3/7x = -9/7

x = -9/7 × 7/3

x = -3

6.9u - 2 - 3.2u - 10 = 2.8

Collect the like terms

6.9u - 3.2u = 2.8 + 12

3.7u = 14.8

u = 14.8/3.7

u = 4

8/5 = - 4a + 7/5 - 2/3a

Collect the like terms

4a + 2/3a = 7/5 - 8/5

4 2/3a = -1/5

14/3a = -1/5

a = -1/5 × 3/14

a = -3/70

8p + 6 - 4p = -14

Collect like terms

8p - 4p = -14 - 6

4p = -20

p = -20/4

p = -5

7 - (5t - 13) = -25

Collect like terms

-5t = -25 - 7 - 13

-5t = -45

t = -45/-5

t = 9

What is the product of −3 1/4 and −1 1/2? Enter your answer as a mixed number, in simplified form, in the box.
Amiraneli [1.4K]

The product of −3 1/4 and −1 1/2  as a mixed number is 4\frac{7}{8}.

The product of −3 1/4 and −1 1/2  as a simplified form is \frac{39}{8}

<h3>What is products and mixed numbers?</h3>

Thew products between two terms can be described as the multiplication operation of the the two terms to give a term which is been performed by the use of the operation sign (*) between the two terms.

The mixed number can be defined as the numbers that contains whole numbers as well as the denominators and numerator.

It should be noted that the product of −3 1/4 and −1 1/2  can be done as (-3\frac{1}{4}  * -1\frac{1}{2}  = -\frac{13}{4} * \frac{-3}{2}  = \frac{39}{8} = 4\frac{7}{8}

One canned juice drink is 25​% orange​ juice; another is 10​% orange juice. How many liters of each should be mixed together in
Talja [164]
11 liters of 25% orange juice, 4 liters of 10% orange juice:

1' let x to be 25% orange juice and y be 10% orange juice

2' .25x+.10y=(15).21

3' x+y=15

4' 2.5x+y=31.5 divide all sides by 10

5' -x-y=-15 multiply all sides by -1

6' 1.5x=16.5

7' x=11

8' y=15-11=4

so 11 and 4 are the answers.

Kanesha wants to find out if people in her community would support turning an unused park into a dog park. Which populations wou
inysia [295]

The most likely populations that Kanesha can pick an appropriate sample for the survey is: <u><em>people who live near the unused park.</em></u>

When running a survey, it is important to use a sample that represents the target population that can sufficiently provide answers to the questions you seek to ask.

Using the a sample from the right population will give you enough data to carryout a survey. The people living close to the unused park would definitely be affected by whatever establishment that is done in the unused park.

Therefore, the most likely populations that Kanesha can pick an appropriate sample for the survey is: <u><em>people who live near the unused park.</em></u>
