Evaluate the following expression at x = -5
-2x-3
Answer:
7.
Step-by-step explanation:
-5 x -2 = 10 (2 negatives being multiplies = positive)

The number of boxes in Warehouse "A" currently totaling 476 is increasing at a rate of 4 boxes per day. The number of boxes in Warehouse "B" currently totaling 986 is decreasing at a rate of 6 boxes per day. In how many days will these two warehouses contain the same number of boxes
Answer:
These two warehouses will contain the same number of boxes in 51 days.
Step-by-step explanation:
Since the number of boxes in Warehouse "A" currently totaling 476 is increasing at a rate of 4 boxes per day, while the number of boxes in Warehouse "B" currently totaling 986 is decreasing at a rate of 6 boxes per day, To determine in how many days these two warehouses contain the same number of boxes, the following calculation must be performed:
Warehouse A = 476 + 4X
Warehouse B = 986 - 6X
476 + 4 x 50 = 476 + 200 = 676
986 - 6 x 50 = 986 - 300 = 686
476 + 4 x 51 = 476 + 204 = 680
986 - 6 x 51 = 986 - 306 = 680
Therefore, these two warehouses will contain the same number of boxes in 51 days.

Answer:
The range of the value of numbers is 8
Step-by-step explanation:
Mathematically, the range refers to the difference between the biggest and the smallest number
From the diagram, the biggest number is 13and the smallest is 5
The difference between this two is the range
we have this as 13 -5 = 8

Anna drove at a constant rate of 63 miles per hour for 3.2 hours. She determined she drove 201.6 miles. Which best explains the reasonableness of Anna’s answer?
There are three digits to the left of the decimal in the factors and three digits to the left of the decimal in the answer, so Anna’s answer is reasonable.
There is one digit to the right of the decimal in the factors and one digit to the right of the decimal in the answer, so Anna’s answer is reasonable.
Anna’s answer is reasonable because 60 times 3 is 180, and 180 is reasonably close to 201.6.
Anna’s answer is reasonable because 70 times 4 is 280, and 280 is reasonably close to 201.6.

The point-slope form of the equation of the line that passes through (-9,-2) and (1,3) is y-3=1/2(x-1) what is the slope-intercept form of the equation for this line
Answer:
y = (1/2)x + 2 1/2
Step-by-step explanation:
y - 3 = (1/2)(x - 1)
Distribute the 1/2
y - 3 = (1/2)x - 1/2
Add 3 to both sides
y = (1/2)x + 2 1/2
Question
Patrick has 4 green hats, 3 blue hats, and 1 orange hat. If he selects a hat at random, what is the
probability of selecting a green hat?
.
0.4
O 0.5
O 0.8
Answer:
0.5
Step-by-step explanation:
First we need to find the total number of hats 4 green hats + 3 blue hats + 1 orange hat = 8 hats P( green hat) = green / total
= 4 / 8
= 1/2

What is the solution to the system of equations
Step-by-step explanation:
[tex]5x + 3y = 13 \\ 7x + 8y = - 16 \\ 5x = 13 - 3y \\ x = \frac{13 - 3y}{5} \\ 7( \frac{13 - 3y}{5} ) + 8y = - 16 \\ 18.2 - 4.2y + 8y = - 16 \\ 3.8y = - 34.2 \\ y = - 9 \\[/tex]
[tex] x = \frac{13 - 3( - 9)}{5} = \frac{13 + 27}{5} = \frac{40}{5} = 8 \\ x = 8 \\ y = - 9[/tex]

Nate’s client said she wanted the width w of every room in her house increased by 2 feet and the length 2w decreased by 5 feet. The polynomial (w+2)(2w−5) or 2w^2 −w−10 gives the new area of any room in the house. The current width of the kitchen is 16 feet. What is the area of the new kitchen?
Answer:
486 ft²
Step-by-step explanation:
For this, you want to replace every w with 16.
This gives (16+2)(2×16-5) or 2×16²-16-10.
I'm going to show this with the first example because the numbers are a bit easier.
You want to begin by working out the brackets. 16+2=18, and 2×16=32, giving us 18(32-5).
32-5=27, giving 18×27 as the equation.
This equals to 486, so the area is 486 ft².

miras kitchen sink holds up to 103.468 liters of water. round this amount to the nearest liter
Answer:
Step-by-step explanation:
Whole numbers
If the decimal is point 5 or greater you can round up.
If the decimal is less that point five you round down.
So your answer is 103
If you want to go to the nearest tenth
if the decimal is greater than 0.05 you round up
if the decimal is less than 0.05 you round down
If want the number to be to the nearest tenth and that's what you have, you leave it alone.

<6 = 109
<7 = 109
Step-by-step explanation:
Angles 6 and 7 are vertical angles so they are equal
7x -24 = 5x+14
Subtract 5x from each side
7x-5x -24 = 5x-5x+14
2x-24 = 14
Add 24 to each side
2x-24 +24 = 14+24
2x = 38
Divide by 2
2x/2 = 38/2
x = 19
<6 = 7x -24 = 7*19 -24 = 109
<7 = 5(19)+14 = 109
A circle has a circumference of 616 cm.
What is the approximate radius of the circle? (Use 22/7
as an estimate for pi.)
A 14 cm
B. 49 cm
C. 98 cm
D. 196 cm
Answer:
π =14 cm
Step-by-step explanation:
Given:
circumference of a circle =616 cm
pie(π)=22/7
circumference of a circle=πr^2
616=22/7 *r^2
616*7/22 =r^2
4312/22 =r^2
196=r^2
[tex]\sqrt{196}[/tex] =r

===========================================
Explanation:
The negative out front of the parenthesis will swap the sign of each term. That means -3c^3 becomes +3c^3, or simply 3c^3. The other terms in the parenthesis are handled the same way.
After distributing the negative through, we add straight down.
The 7c^3+3c^3 becomes 10c^3
Then we have -5c^2+(-2c^2) become -7c^2
Finally, 2c+2c simplifies to 4c
Answer:
10C³-7C²+4C
7c³-(-3c³) -5c²-(+2c²) +2c-(-2c)
