Answer:

Step-by-step explanation:

You may recall that when you learned multiplication of decimals, there were two facts involved:

__

Here, we combine these facts.

Multiplying the decimal number 1.304 by 1000000 will add 6 zeros to the right of 1304 to make it 1304000000. Placing the decimal point in this product so there are 3 decimal digits (as there are in 1.304) makes this number be ...

  1,304,000.000 . . . . . . product of 1.304 and 1,000,000

You will notice the decimal point in 1.304 has effectively moved 6 places to the right.

Answer:

7x

Step-by-step explanation:

when you add -1 aka -x to 8 8x it takes away one, so 7x

3x+5=0

3x=0-5

3x=-5

Divide both sides by 3

-1.6666.......

Hope it helps.

As for mod 9, I don't understand.

Answer:

[tex]x=-\cfrac{5}{3}[/tex]

[tex]x=-1.666[/tex]

Step-by-step explanation:

[tex]3x+5=0[/tex]

[tex]3x+5-5=0-5[/tex]

[tex]3x=-5[/tex]

[tex]\cfrac{3x}{3}=\cfrac{-5}{3}[/tex]

[tex]x=-\cfrac{5}{3}[/tex]

Answer:

pretty sure it's 10 1/2

Answer:

I think the answer is D. 12 1/2

Step-by-step explanation:

If you add up the two thing it becomes: 15 cups of flour and 6 cups of milk. So if you divide 15 by 6, it's 2.5. Now all you have to do is 5 (since there are 5 cups of milk) times 2.5, and you get 12.5. And 12.5 is 12 1/2 in fraction form. Hence, the answer is D. 12 1/2.

Answer:

he is wrong becuase 89 times a number greater than 0 cannot result in a product greater than the number

Step-by-step explanation:

Based on real algebra properties, we know that the product of  8/9 and 2 and 3/4 is not 3 and 1/4.

The multiplication of two positive integers equals another positive integer. Each term of a multiplication can be rewritten as sums of multiples of 10, which can be simplified by algebra:

  Given;   Definition of multiplication

 8/9 and 2  = 26/9

3/4

The product is;

26/9 x 3/4

= 13 x 1/6

= 13/6

Based on real algebra properties, we know that the product of  8/9 and 2 and 3/4 is not 3 and 1/4.

Answer:

[tex]y = 2\, (x - 9)^{2} - 1[/tex].

Step-by-step explanation:

If the vertex of a parabola is [tex](h,\, k)[/tex], there would exist a constant [tex]a[/tex] ([tex]a \ne 0[/tex]) such that the following would be an equation for this parabola:

[tex]y = a\, (x - h)^{2} + k[/tex].

The equation above is in the vertex form.

In this question, the vertex of this parabola is [tex](9,\, -1)[/tex]. (Such that [tex]h = 9[/tex] and [tex]k = -1[/tex].) Therefore, the equation of this parabola in the vertex form would be:

[tex]\text{$y = a\, (x - 9)^{2} + (-1)$ for some $a \ne 0$}[/tex].

It was also given that the point [tex](7,\, 7)[/tex] is on the parabola. In other words, if [tex]x = 7[/tex] and [tex]y = 7[/tex], the equation of this parabola ([tex]\text{$y = a\, (x - 9)^{2} + (-1)$}[/tex]) should be satisfied. In other words:

[tex]7= a\, (7 - 9)^{2} + (-1)[/tex].

Solve this equation for [tex]a[/tex].

[tex]a = 2[/tex].

Therefore, the equation of this parabola in vertex form would be[tex]y = 2\, (x - 9) + (-1)[/tex], which is equivalently [tex]y = 2\, (x - 9)^{2} - 1[/tex].

she bought 10 pencils and 5 erasers

Let x represent the number of pencils and y represent the number of erasers.

Gabby wants to spend exactly $2.00 on pencils and erasers, hence:

0.15x - 0.1y = 2        (1)

Therefore x = 10 and y = 5

Therefore she bought 10 pencils and 5 erasers.
