Answer:

x = 1.8

Step-by-step explanation:

Put the known value in the equation and solve for x.

y = -10x +16

-2 = -10x + 16 . . . . . use -2 for y

-18 = -10x . . . . . . . . subtract 16

1.8 = x . . . . . . . . . . divide by -10

The value of x is 1.8 when y = -2.

Find the ratio 2 1/2 to 6 1/2

ivanzaharov [21]

Answer:

The ratio 2 1/2 to 6 1/2 is

$\frac{5}{13}\\or\\5:13$

Step-by-step explanation:

Ratio:

In mathematics, a ratio is a relationship between two numbers indicating how many times the first number contains the second.

It is also the Fraction

For example, if a bowl of fruit contains eight apples and six kiwis, then the ratio of apples to kiwis is eight to six.

i.e 8:6, which is equivalent to the ratio 4:3.

Now here,

$2\frac{1}{2}=\frac{4+1}{2}\\\\2\frac{1}{2}=\frac{5}{2}\\\\and\\\\6\frac{1}{2}=\frac{12+1}{2}\\\\6\frac{1}{2}=\frac{13}{2}$

Ratio of 2 1/2 to 6 1/2

$\frac{\frac{5}{2}}{\frac{13}{2}} = \frac{5}{13}\ \textrm{The number 2 will be cancelled from Numerator and Denominator} \\\\Hence,\\Final\ Ratio\ is\ 5 :13$

$\frac{5}{13}$

Find the product<br> (2n-2)(2n^2-3n+5)

atroni [7]

Answer:

4n^3 -10n^2 +16n -10

Step-by-step explanation:

Use the distributive property to eliminate parentheses, then combine like terms.

= 2n(2n^2 -3n +5) -2(2n^2 -3n +5)

= 4n^3 -6n^2 +10n -4n^2 +6n -10

= 4n^3 +n^2(-6-4) +n(10+6) -10

= 4n^3 -10n^2 +16n -10
