Step-by-step explanation:

remember : any "dot" operation comes before any "dash" operation.

so, every multiplication or division has to be done before any addition or subtraction is done.

the priority is

1. brackets

2. exponents

3. multiplication and divisions

4. additions and subtractions

for operations on the same level we usually go left to right.

I am not sure what the problem is to keep that in mind.

but it is essential that you do.

so, what you have here is

(8÷0.1 + 12×3) - 2

8÷0.1 = 80

12×3 = 36

80 + 36 = 116

116 - 2 = 114

so, the result is 114.

I hope this helps.

This is called as sampling error or sampling variability. Sampling error is the variability that happens because the value of a sample statistic varies from sample to sample. Sampling error is acquired when a population is estimated from a subset, or sample.

72 is equal to 80% of a number n. Write and solve and equation to find n. Write the percent as a decimal.

valentina_108 [34]

Well I'm not sure what the answer would be since I'm not that smart but I did get the answer of 90, I did this by dividing 72 by 80 which equals .9 and I multiplied that by 100 and got 90.

Problem 3

Murljashka [212]

Answer:

$-\frac{2}{5}$

Step-by-step explanation:

Given expression:

2x + 5y = -10

The equation of a straight line is;

y = mx + c

y and x are the coordinates

m is the slope

c is the intercept

Now;

let us write the given expression in slope intercept format;

2x + 5y = -10

5y = -2x - 10

y = $-\frac{2x}{5}$ - 2

So, the slope of the line is $-\frac{2}{5}$

Anyone know how to find the constant of proportionality???!!!

dmitriy555 [2]

Answer:

You find the constant of proportionality by how much u need to add or subtract the same number to get the same answer and in a graph you need to see if the line goes through the origin (0,0).
