Shawna, Dexter, and Tilana are solving the equation Negative 2.5 (5 minus n) + 2 = 15.
Shawna says, “I can begin by dividing each side of the equation by –2.5 to get 5 minus n minus StartFraction 2 over 2.5 EndFraction = Negative StartFraction 15 over 2.5 EndFraction.”
Dexter says, “I can begin by distributing Negative 2.5 to get Negative 12.5 + 2.5 n + 2 = 15.”
Tilana says, “I can begin by multiplying each side of the equation by Negative StartFraction 1 over 2.5 EndFraction to get 5 minus n minus 0.8 = negative 6.”

Four statements are given. Which one is true?
The opposite of a 0°F wind chill is 0°F.
A temperature of –(–8°F) is the same as a temperature of –8°F.
A wind chill of 0°F and one of –1°F are examples of opposite numbers.
On a thermometer, 5°F would be located on the opposite side of 0 from –(–5)°F.

Some students recorded how many minutes they spent on the phone in one day. They put the results in a Stem-and-Leaf Plot.
What is the mean number of minutes spent on the phone?
Answers
Explanation:
The data from the stem-and-leaf plot is:
10,
24,25,26,
30,30,32,33,
40,45,46
Add up those values
10+24+25+26+30+30+32+33+40+45+46 = 341
Then divide over n = 11 which is the sample size.
341/11 = 31 is the arithmetic mean.

The table shows the diameters of the planets in our solar system. Assume that a basketball whose diameter is 25 centimeters represents the planet Jupiter. Find the scale (ratio) between Jupiter and the basketball. Then use this ratio to find the scaled diameter of the other planets. Enter these numbers into the table. (Saturn has been done for you.) Finally, choose a real-world spherical or nearly spherical object that matches the scaled diameter of each planet.
Saturn is shown as an example. To find what Saturn’s size would be after adjusting it to scale, follow these steps. Let the scaled diameter of Saturn be d centimeters. If Jupiter’s diameter, 142,984 kilometers, is scaled to 25 centimeters, Saturn’s diameter of 120,536 kilometers will be scaled to about 21 centimeters:
142,984/25 = 120,536/d
d = 120,536×25/142,984
d ≈ 21 cm

help me pls: Select the fraction that is equivalent to two thirds.
a. 2/12
b. 4/12
c. 3/6
d. 8/12
Answers
Answer: D. 8/12
Step-by-step explanation:
8/12 is the equivalent fraction to 2/3 which we can see when the fraction is put into it's simplest form.
See here: In the fraction 8/12, there is an 8 as the numerator (top number) and a 12 as the denominator (bottom number). When we look at these, it is crucial to find the GCF (greatest common factor) so it can be put into simplest form. In this case, 8's factors are (1x8) and (2x4). 12's factors are (1x12), (2x6), and (3x4). Looking at these factors for both numbers, we can see that they both have a 2 and a 4. However, because the 4 is the greater number, it is our GCF. Now divide the numerator and the denominator by 4 to get 2/3

The volume of a cylinder is 90 pi cm^3 . If the radius is 3cm, what is the height of the cylinder?
Answers
Answer:
The height is 10 cm
Step-by-step explanation:
The volume of a cylinder is given by
V = pi r^2 h where r is the radius and h is the height
90 pi = pi r^2 h
We know the radius is 3
90 pi = pi (3)^2 h
90 pi = 9 pi h
Divide each side by 9 pi
90 pi /9 pi = 9 pi h / 9pi
10 =h
The height is 10 cm
The height of the cylinder is 9 cm. This can be calculated by using the equation of the volume of the cylinder.
The volume of a cylinder = 90 π \(cm^{3}\) The radius of the cylinder = 3 cm The equation for the volume of a cylinder = π\(r^{2}\)h ∴ The volume of the cylinder = π × \(3^{2}\) × h ⇒ 90 π = π × 9 × h
Canceling π from both sides ⇒ 90 = 9 h h = 90 ÷ 9 h = 10 cm Thus, the height of the cylinder is 9 cm.

If you have a question something like this: "Determine which integer makes the inequality 6(n − 5) < 3(n + 4) true."

Write an equation in standard form of the line that passes through (−6,−10) and has the slope m=1/6.
Answers
Step-by-step explanation:
y-b=m(x-a)
y--10=1/6(x--6)
y+10=1/6(x+6)
6y+60=1(x+6)
6y+60=1x+6
6y=1x-54
y=1/6x-54/6
y=1/6x-9
The equation of line is y= 1/6x - 9.
What is Slope?A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the
change in y coordinate with respect to the change in x coordinate as,
m = Δy/Δx
where, m is the slope
Given:
slope= 1/6
and, passes through (−6,−10)
Now, using slope intercept form
y- a =m (x- b)
y - (-10)= 1/6(x -(-6))
y + 10= 1/6( x + 6)
y + 10 = 1/6x + 1
y= 1/6x - 9
Hence, the equation of line is y= 1/6x - 9.
