John claims the following two expressions are equivalent.
- 215y - 3) = - 10y - 6
John's work in determining an expression equivalent to the first expression is shown below.
- 2/5y - 3)
= (-2x5y) - (-2x - 3)
= - 10y-6
Which statement explains why John's claim is incorrect?
He should have subtracted (-2 * 3) resulting in the expression–10y + 6.
He should have only multiplied 3 by -2 resulting in the expression 5y - 6.
He should have only multiplied Sy by -2 resulting in the expression-10y - 3.
He should have only multiplied 3 by -2 and subtracted (-2 * 3) resulting in the expression 5y + 6.

Answers

Answer:

the answer is B. He should have only multiplied 3 by –2 resulting in the expression 5y – 6.

Step-by-step explanation:

In the given expressions, the reason for John's claim being incorrect would be:

B). He should have only multiplied 3 by –2 resulting in the expression 5y – 6.

Given,

The two expressions i.e. [tex](-215y - 3) = - 10y - 6[/tex]The mistake that John makes is that he multiplies the entire equation by -2 as shown in [tex]= (-2x5y) - (-2x - 3)[/tex] which makes it incorrect.In order to rectify this mistake, only 3 was suppossed to be multiplied by -2 so that the outcome comes out as [tex]5y - 6[/tex].

Thus, option B is the correct answer.

7( x+3 ) < 5x + 13

Answers

Answer:

[tex]\boxed {x < -4}[/tex]

Step-by-step explanation:

Solve the following inequality:

[tex]7(x + 3) < 5x + 13[/tex]

Use Distributive Property:

[tex]7(x + 3) < 5x + 13[/tex]

[tex]7x + 21 < 5x + 13[/tex]

-Take [tex]5x[/tex] and subtract it from [tex]7x[/tex]:

[tex]7x + 21 - 5x < 5x - 5x + 13[/tex]

[tex]2x + 21 < 13[/tex]

Subtract both sides by [tex]21[/tex]:

[tex]2x + 21 - 21 < 13 - 21[/tex]

[tex]2x < -8[/tex]

Divide both side by [tex]2x[/tex]

[tex]\frac{2x}{2} < \frac{-8}{2}[/tex]

[tex]\boxed {x < -4}[/tex]

the answer to this is x<-4

Sebastián was saving $8.50 each week in order to have enough money for a phone that costs $122. If his father started him off with $25, write an inequality that can be used to determine the minimum number of whole weeks, w, Sebastián will need to save.

Answers

Step-by-step explanation:

122 - 25

y= 8.5x + 25

97/8.50 <

11.4 --> 12

x < 12

Answer:

25 + 8.50w ≥ 122

Step-by-step explanation:

Given that:

Amount saved per week = $8.50

Cost of phone = $122

Starting amount = $25

Minimum Number of whole weeks (w) Sébastien will need to save :

Starting amount + (weekly saving * number of weeks) ≥ 122

25 + 8.50w ≥ 122

8.50w ≥ 122 - 25

8.50w ≥ 97

w ≥ 97/8.50

w ≥ 11.4117

Number of whole weeks = 12

Answers

Answer:

C. The value of a is the number that the x-values are multiplied by to get to the corresponding y-values. So, a = 3.

Step-by-step explanation:

Given the points (5, 15) and (-5, -15) are plotted using the equation y = a•x, this shows a proportional relationship between y and x.

Thus using any of the points, say (5, 15), x = 5, and y = 15, thus:

a = y/x = 15/5

a = 3

Therefore, the value of a, which is 3, is the number that the x-values, 5 and -5, are multiplied by to get the corresponding y-values, 15 and -15.

As we can see, if we multiply each of the x-values by 3, it will give us their corresponding y-values.

Answers

Answer:

y = [tex]\frac{-2x}{3}[/tex]

Step-by-step explanation:

Distribute 5 to 2x and 3y by multiplying each by 5

10x + 15y

Isolate y to one side of the equation

15y=-10x

Divide each side by 15

y = [tex]\frac{-2x}{3}[/tex]

Answer:

5(2x + 3y) = 10x + 15y

Step-by-step explanation:

There is one particular way to find an equivalent expression which I am assuming is what the problem is looking for. When given a factored expression in the form of a binomial (two terms), by creating an equivilent expression, you can distribute the binomial inside the parenthesis factored by the coefficient 5. So 5(2x + 3y) = 5(2x) + 5(3y) = 10x + 15y.

5 is also the greatest common factor of 10x + 15y which is why this expression simplifies down to the equivilent expression 5(2x + 3y).

10x + 15y as a GCF is really the GCF of 10 and 15. What you do is individually split each number into all its possible factors(set of whole numbers that multiply to that number), and then find the factor that they both share.

For example, 10 has factors of 5, 2, 1, 10. And 15 has factors of 15, 1, 5, 3.

Notice how 5 appears in both.
