Which number line best shows how to solve −8 − (−2)? (5 points)

1 answer:

6 0

A number line from negative 10 to 10 is shown, with numbers labelled at intervals of 2. An arrow is shown from point 0 to negative 8. Another arrow points from negative 8 to negative 6. Therefore, option C is the correct answer.

<h3>What is a number line?</h3>

A number line is a straight line with numbers placed at equal intervals. Positive numbers are placed to the right of 0 and negative numbers are placed to the left of zero.

When a number (x) is added x unit is moved to the right while if a number (x) is subtracted x unit is moved to the left.

Now, solve -8 - (-2)

= -8 + 2=-6

So, a number line from negative 10 to 10 with numbers labelled at intervals of 2. An arrow is shown from point 0 to negative 8 then since 2 is added, we move 2 units right from negative 8 to negative 6.

Therefore, option C is the correct answer.

14. The area of a rectangle is 375 square inches and it’s perimeter is 80 inches. Find both the length and width.

Pavel [41]

Answer:

Length $=25$ inches

Width $= 15$ inches

Step-by-step explanation:

Let $l$ = length of rectangle, $w$ = width of rectangle

Given the area and the perimeter of the rectangle, we can write:

$lw = 375$

$2l+2w=80$

So:

$l+w = 80\div2$

$=40$

$l=40-w$

Now, we can use substitution to find the value of $w$ :

$lw = 375$

$(40-w)w = 375$

$40w-w^2 = 375$

$375+w^2-40w = 0$ (Quadratic equation)

$(w-15)(w-25) = 0$

∴ $w = 15, 25$

We can use substitution again to find the value of $l$

$lw = 375$

$l=375\div w$

$=25,15$

∵ Length usually refers to the longer side of a rectangle, ∴ length $=25$ inches and width $=15$ inches.

Hope this helps :)

At the neighborhood block party, Camille served 1/2 of a gallon of hot chocolate and 1/3 of a gallon of apple cider. How much mo

Oksi-84 [34.3K]

Answer:

1/6 more hot chocolate than apple cider.

Step-by-step explanation:

In order to complete this, you first have to make both numbers have the same denominator.

2: 2, 4, 6

3: 3, 6

The new denominator is 6.

1/2 - 3/6

1/3 - 2/6

These are the new fractions after making the numbers have common denominators.

3/6 - 2/6 = 1/6

Camille serves 1/6 more hot chocolate than apple cider.

Through: (-5, -5), slope=2/5

kakasveta [241]

For this case we have that by definition, the equation of a line in the slope-intersection form is:

$y = mx + b$

Where:

m: It is the slope

b: It is the cut point with the y axis

The slope is: $m = \frac {2} {5}$

Thus, the equation is of the form:

$y = \frac {2} {5} x + b$

We substitute the given point and find "b":

$-5 = \frac {2} {5} (- 5) + b\\-5 = -2 + b\\-5 + 2 = b\\b = -3$

Finally, the equation is:

$y = \frac {2} {5} x-3$

Answer:

$y = \frac {2} {5} x-3$

50 POINTS!!!!! HELP Soybean meal is 16% protein; cornmeal is 8% protein.How many pounds of each should be mixed together in orde

tia_tia [17]

The first thing we are going to do for this case is define variables.
We have then:
x: Amount of soybean meal
320 - x: quantity of cornmeal
We now write the equation that models the problem:
$0.16x + 0.08 (320-x) = 0.09 (320)
$
Rewriting we have:
$0.16x + 25.6 - 0.08x = 28.8
$
From here, we clear x:
$0.16x - 0.08x = 28.8 - 25.6

0.08x = 3.2

x = 3.2 / 0.08

x = 40$
Then, the amount of Soybean meal is:
$x = 40 lb
$
The amount of cornmeal is:
$320 - x = 320 - 40 = 280 lb
$
Answer:
cornmeal: 280 lb
Soybean: 40 lb.

Gross worldwide sales in Mattel's Wheels (Hot Wheels) brand was $885.1 million in 2016 and $847 million in 2017. Calculate the a

attashe74 [19]

Answer:

Step-by-step explanation:

Absolute Change = final change in 2017 sales - initial change in 2016 sales = $847,000,000 - $885,100,000 = 38,100,000

Relative Change = (Final - Initial change)/initial change x 100% = 38,100,000/885,100,00 x 100% = 381/8851 x 100% = 0.0430459835 x 100% = 4.30%
