Answer:

First answer is 5 hours

Second answer is 7 weeks

First question explanation:

Make an equation to find out when the companies prices are equal

Let x be the number of hours, so we isolate that one

10 +5x = 7x

subtract 5x from both sides

10= 2x

5=x

Second question explanation:

Same as the first one, setting up an equation as follows:

let x be number of weeks

500-20x=150+30x

add 20x to both

500 = 150 + 50x

subtract 150 from both sides

350 = 50x

divide both sides by 50

7 = x

kotykmax [81]

By verbal reasoning, the pair of words required can be obtained from the

synonyms of the given pair.

Correct response:

  • <u>Variable</u>; <u>supposition</u>
<h3>Analysis used for making the above selection</h3>

Prediction: A prediction is a statement indicating the result to be

expected from a trial or test, based on deductive reasoning from a

theory or hypothesis.

An explanation is a statement describing a phenomenon and is taken as

an  hypothesis.

A variable is an outcome of a test or trial, or observation.

A supposition is a held notion or belief that is similar to a hypothesis.

Therefore;

Prediction is to explanation as <u>variable</u> is to <u>supposition</u>.

How do I find the product when multiplying with decimals<br><img src="https://tex.z-dn.net/?f=0.36%20%5Ctimes%202.4" id="TexForm
stellarik [79]

Step 1:

first let us convert the two decimals into fractions.

0.36=36/100 (since there are two digits after decimal point we divide by 100)

2.4=24/10 (since there are one digit after decimal point we divide by 10)

now we can multiply the fractions

\frac{36}{100}×\frac{24}{10}

multiplying numerator with numerator and denominator with denominator:

\frac{36*24}{100*10}

=\frac{864}{1000}

Now we can convert this back to decimal

864/1000=0.864, moving decimal three digits to the left since we have three zeros in the denominator that is 1000.

Answer=0.864

How many extraneous solutions does the equation below have?
FrozenT [24]

<u>Answer</u>

0


<u>Explanation</u>

(2m)/(2m+3)-(2m)/(2m-3)=1

Simplifying the left hand first

(2m)/(2m+3)-(2m)/(2m-3) = {2m(2m-3) - 2m(2m+3)}/(4m²-9)

                                        (4m²-6m-4m²-6m)/(4m²-9)

                                         = (-12m) / (4m²-9)

Now this equet to 1

(-12m) / (4m²-9) = 1

-12m =  4m²-9

4m²+ 12m -9 =0 ⇒⇒⇒ This is a quadratic equation that has 2 real solutions.

4m²+ 12m -9 =0

m² + 3m + (3/2)²= 9/4 + 9/4

(m + 3/2)² = 18/4

m = √18/2 - 3/2                or m = -√18/2 - 3/2

    = 0.621                                       = -3.621

So we can say that the equation has NO extraneous solutions.

Answer = 0
