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.

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.

Answer:

18 will be the number of sides.

Step-by-step explanation:

As we know that the sum of exterior angles of a polygon is 360°.

The formula is:

The exterior angle of a polygon = 360 ÷ number of sides

As each exterior angle of a regular polygon is 20°.

so putting the value exterior angle 20° in the formula

The exterior angle of a polygon = 360 ÷ number of sides

20 = 360 ÷ number of sides

20 = 360/number of sides

so the number of sides will be:

number of sides = 360/20

= 18

Therefore, 18 will be the number of sides.

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.
