Step-by-step explanation:

wrong 4+6x2=16 This is right answer

Answer:

True

Step-by-step explanation:

Bodmas you start with the multiplication before adding the 4 so its 6×12=12+4 which is equal to the right hand side

Answer:

15 newspapers

Step-by-step explanation:

30 newspapers spread over 2 piles is 30/2 = 15 newspapers

The question doesn't say spread but in language if it doesn't separate we can say the group word spread as it is most likely to be a group total of 30 spread over 2 piles.

Step-by-step explanation:

y = ax +b

2 = 0a+ b => b = 2

4 = -2a + b

4 = -2a +2

2a = 2-4

2a = -2

a = -1

so, y = -x + 2

Answer:

To find the point that's one-third of the distance from (–4,1) to the other endpoint, (8,7): Replace x1 with –4, x2 with 8, y1 with 1, y2 with 7, and k with 1/3. Subtract the values in the inner parentheses. Do the multiplication and then add the results to get the coordinates

Answer:

y=84 , y= -5

Step-by-step explanation:

put -9 in the x value

remove the power and that will be 81

then 81 +3=84

take out the square root of -9 in the other machine

Answer:

I don't know sorry about that

The total amount needed is $165 if your class earned $55.00 Saturday afternoon by washing cars to raise money for a class trip.

Fraction number consists of two parts, one is the top of the fraction number which is called the numerator and the second is the bottom of the fraction number which is called the denominator.

It is given that:

Your class earned $55.00 Saturday afternoon by washing cars to raise money for a class trip. This is 1/3 of the money needed for the trip.

Let x be the total amount needed:

A linear equation in one variable can be framed as follows:

1/3 of x = 55

x/3 = 55

x = 55x3

x = $165

Thus, the total amount needed is $165 if your class earned $55.00 Saturday afternoon by washing cars to raise money for a class trip.

Answer:

[tex]\frac{3(a-7)}{4x(a-4)}[/tex]

Step-by-step explanation:

One is given the following expression:

[tex]\frac{2a^2-9a-35}{12x^3}*\frac{9x^2}{2a^2-3a-20}[/tex]

The most logical first step to solve this equation is to factor it. Rewrite each quadratic equation as the product of two linear equations. Unfortunately, no additional explanation can be provided. To prove that the product of the two linear terms are the factors of the quadratic term, one must distribute and simplify,

[tex]\frac{2a^2-9a-35}{12x^3}*\frac{9x^2}{2a^2-3a-20}[/tex]

[tex]\frac{(2a+5)(a-7)}{12x^3}*\frac{9x^2}{(2a+5)(a-4)}[/tex]

Now simplify this expression, then cancel common terms in the numerator and denominator,

[tex]\frac{(2a+5)(a-7)}{12x^3}*\frac{9x^2}{(2a+5)(a-4)}[/tex]

[tex]\frac{9x^2(2a+5)(a-7)}{12x^3(2a+5)(a-4)}[/tex]

[tex]\frac{3(a-7)}{4x(a-4)}[/tex]
