Answer:

Grace is right

Step-by-step explanation:

3(2-x)-2(6x-8)=

so:

3×2 is 6

3×(-x) is -3x

-2×6x is -12x

-2×(-8) is 16 because -×- equals +

3(2-x)-2(6x-8)

=6-3x-12x+16

= -15x+22

Answer:

Grace

Step-by-step explanation:

Chelsea is wrong because the -2(6x - 8) cancels out the subtraction in the bracket so it should be -12x + 16

Roan did the same.

wariber [46]

Answer:

0.25 (inches?)

Step-by-step explanation:

the equation is:

y=mx+b

y is the length of her hair, the dependent variable, the outcome

m is the slope, which is in this case the growth of her hair in a month

x is the independent variable, or the number of months

b is how long her hair is to start with, which is 12 in

we are looking for m, which is the growth of her hair per month, which is given as 0.25 inches, so that would be the answer

stepladder [879]
<h3>The absolute error is 6</h3><h3>The percent error is 16.22 %</h3>

<em><u>Solution:</u></em>

Given that,

Actual volume of his bathtub is 37 gal

Estimate is 31 gal

<em><u>Find the absolute error</u></em>

Absolute Error = | Measured Value - Actual Value |

Absolute Error = | 31 - 37 |

Absolute Error = 6

<em><u>Find the percent error</u></em>

Percent\ error = \frac{\text{estimate - actual}}{actual} \times 100

Substituting we get,

percent\ error = \frac{31-37}{37} \times 100\\\\percent\ error = \frac{-6}{37} \times 100\\\\percent\ error = -16.22

Negative sign means percent decrease

Thus percent error is 16.22 %
