0.4(10x-15)+8=-3-x

please give me an example as well. I'd really appreciate it.

Answers

Answer 1

First, you would distribute the 0.4 through the parentheses

4x-6+8=-3-x

Then combine like terms

4x+2=-3-x

Get x on its own side,

5x=-5

Then divide by 5

x=-1

Check Answer by plugging in x

0.4(10(-1)-15)+8=-3-(-1)

0.4(-25)+8=-3+2

-10+8=-2

-2=-2

Answer 2

X=-1 so that should be the answer

4.5 L of orange juice is needed to add to 18 L of pineapple juice to make the fruit juice recipe with the ratio of 2 parts orange juice to 8 parts pineapple juice. The correct option is B.

What is an expression?

An expression is a grouping of one or more mathematical or logical operators, operands (values, variables, or other expressions), and brackets in mathematics and computer programming that denote a computation that can be evaluated to generate a value.

The correct proportion that can be used to find the amount of orange juice, j, that is needed to add to 18 L of pineapple juice is:

2/8 = j/18

This proportion is based on the ratio of 2 parts orange juice to 8 parts pineapple juice in the recipe. We can use this proportion to find the amount of orange juice, j, that is needed to add to 18 L of pineapple juice by cross-multiplying:

2/8 = j/18

2 × 18 = 8 × j

36 = 8j

j = 4.5

Therefore, 4.5 L of orange juice is needed to add to 18 L of pineapple juice to make the fruit juice recipe with the ratio of 2 parts orange juice to 8 parts pineapple juice.

Using absolute values

|-44| = 44

|-34| = 34

b. How much change will Malia receive? Write an equation and solve.

Answers

Answer:

Malia's allowance changed from $10.00 to $(10 - 2x) after buying ice cream cones.

Step-by-step explanation:

Answers

Yes they should plan for the skate park because the samples had about 46.4% people

Yes, they should plan for the skate park because the sample had about 46.4% people vote yes. Thus, option C is correct.

What is a sample?

A sample is characterized as a more workable and compact version of a bigger group. a smaller population that possesses the traits of a bigger group. Since the population size exceeds the threshold big to accommodate all those who participated in the test, a subsection of the population is utilised in statistical analysis.

The details that are given:

the needed percentage to build a skateboard = 40 %

The total number of voters = 125

The people who responded yes = 58

The percentage of the people who voted will be:

= 58/125 * 100

= 46.4 %

As the value of 46.4 % > 40%, the individual should be able to vote.

Therefore, option C is correct.

Find the slope from the graph.

-1/2

-4/3

3/4

-3/4

Answers

Answer: 3/4

Step-by-step explanation:

To find the slope from the graph, we need to look at the rise and run of the line. The slope is the ratio of the vertical change (rise) to the horizontal change (run).

Let's analyze the given options:

-1/2: This means that for every 2 units the line moves horizontally, it moves down 1 unit vertically.

-4/3: This means that for every 3 units the line moves horizontally, it moves down 4 units vertically.

3/4: This means that for every 4 units the line moves horizontally, it moves up 3 units vertically.

-3/4: This means that for every 4 units the line moves horizontally, it moves down 3 units vertically.

So, from the given options, the slope is 3/4. This indicates that for every 4 units the line moves horizontally, it moves up 3 units vertically.

Remember, the slope of a line is a measure of how steep the line is. It tells us how much the line is rising or falling as we move along the x-axis.

Use the slope formula to solve this question:

The slope formula is as followed:

y₂ - y₁

x₂ - x₁

where (x₁, y₁) and (x₂, y₂) are two sets of coordinates

Pick the two points on the line:

(0, 5) (4, 2)

Now, plug them into the equation and solve:

y₂ - y₁

x₂ - x₁

[tex]\frac{2-5}{4-0}[/tex] = [tex]\frac{-3}{4}[/tex]

explanation:

Negative number raised to an even power is positive

For example let's look at (-7)6 , where (-7) , a negative number, is raised to 6 , an even exponent :

(-7)6 can be written as (-7)•(-7)•(-7)•(-7)•(-7)•(-7)

Now, using the rule that says minus times minus is plus, (-7)6 can be written as (49)•(49)•(49) which in turn can be written as (7)•(7)•(7)•(7)•(7)•(7) or 76 which is positive.

We proved that (-7)6 is equal to (7)6 which is a positive number

Using the same arguments as above, replacing (-7) by any negative number, and replacing the exponent 6 by any even exponent, we proved which had to be proved

Yes, he is correct, because if in one yard is 36 inches, and half a yard is 18 inches, if you multiply 36 by 5, you get 180. Then add the half yard of 18 to have 5.5 yards, or 198 inches. :)

What constant of proportionality relates defective bulbs to total bulbs?

Answers

The answer is very simple you can simply put it as 0.1

The constant of proportionality that relates defective bulbs to total bulbs is 1 / 9.

What is Constant Proportionality?

The ratio connecting two given numbers in what is known as a proportional relationship is the constant of proportionality. Constant ratio, constant rate, unit rate, constant of variation, and even rate of change are other names for the constant of proportionality.

Given:

One out of every 9 light bulbs is defective.

Total bulbs = 9

So, Defective bulbs = 1

Thus, Constant of proportionality = Defective bulbs / Total bulbs.

Constant of proportionality = 1 / 9

Hence, the constant of proportionality that relates defective bulbs to total bulbs is 1 / 9.
