-2y+6=-12
What does y equal?
Answer:
y = 9
Step-by-step explanation:
-2y+6=-12
subtract 6 on both sides: -2y=-18
divide both sides by -2: y=9
Answer:
[tex]y = 9[/tex]
Step-by-step explanation:
1) Subtract 6 from both sides.
[tex] - 2y = - 12 - 6[/tex]
2) Simplify -12-6 to -18.
[tex] - 2y = - 18[/tex]
3) Divide both sides by -2.
[tex]y = \frac{ - 18}{ - 2} [/tex]
4) Two negative makes a positive.
[tex]y = \frac{18}{2} [/tex]
5) Simplify 18/2 to 9.
[tex]y = 9[/tex]
So, Yherefor, the answer is, y = 9.

Amelia's family took a road trip to Niagara Falls. Amelia fell asleep after they had travelled 931 miles. If the total length of the trip was 980 miles, what percentage of the total trip had they travelled when Amelia fell asleep?
Answer:
95%
Step-by-step explanation:
Total distance of trip = 980 miles
Miles covered when Amelia slept = 931 miles
what percentage of the total trip had they travelled when Amelia fell asleep?
Miles yet to be covered = 980 miles - 931 miles
= 49 miles
percentage of the total trip had they travelled when Amelia fell asleep = 931 / 980 × 100
= 0.95 * 100
= 95%
Answer:
95%

If 30.0 moles of oxygen are used, how many grams of water will form?
Answer:
3
Step-by-step explanation:
The amount of water released will be 1.081 grams.
How to calculate the amount of water released in a chemical reaction?The balanced chemical equation for the reaction between hydrogen gas and oxygen gas to form water is:
2H₂+ O₂ -> 2H₂O
According to the equation, 2 moles of hydrogen gas react with 1 mole of oxygen gas to form 2 moles of water. This means that the mole ratio of oxygen gas to water is 1:2.
If 30.0 moles of oxygen gas are used, we can use this mole ratio to calculate the number of moles of water that will form:
30.0 moles O₂ x (2 moles H2O / 1 mole O₂) = 60.0 moles H₂O
So, 60.0 moles of water will form.
To convert from moles to grams, we need to use the molar mass of water, which is approximately 18.015 g/mol. Therefore:
60.0 moles H₂O x 18.015 g/mol = 1,081 g
So, 1,081 grams of water will form.

Jess has 5 bouquets with 12 roses in each bouquet. Kyle has 12 bouquets with 5 roses in each bouquet. Which equation uses the commutative property to show that Jess and Kyle have an equal number of roses?
Answer:
Number of bouquet * roses per bouquet = roses per bouquet * Number of bouquet
5 * 12 = 12 * 5
60 = 60
Step-by-step explanation:
Given that :
Jesse :
Number of bouquet = 5
Roses per bouquet = 12
Kyle:
Number of bouquet = 12
Roses per bouquet = 5
To show commutativity :
Number of bouquet * roses per bouquet = roses per bouquet * Number of bouquet
5 * 12 = 12 * 5
60 = 60
Answer:
The answer is D.
Step-by-step explanation:

Answer:
Step-by-step explanation:
Find h when v = 20 and r = 3
Putting values in the formula
20 = (3.14)(3)2h
20 = (3.14)(9)h
20 = 28.26h
20/28.26 = h
R when v = 100 and h = 5
100 = (3.14)r2(5)
100/5 = 3.14r2
20 = 3.14r2
20/3.14 = r2
6.36 = r2
Square root on both sides
2.52 = r

II) Simplify/Evaluate:
2² + 5(2) + 6
4 + 10 + 6

I) Setup the equation:
g(t) = 5t - 2 = 18
5t - 2 = 18
II) Solve it:
Reorder the terms:
-2 + 5t = 18
Add 2 to each side of the equation:
-2 + 2 + 5t = 18 + 2
Simplify:
0 + 5t = 18 + 2
5t = 18 + 2
5t = 20
Divide each side by 5:

The coordinates of the point S of the line RS having midpoint T are found to be (10, -7).
What is mid point?In geometry, the midpoint is the middle point of a line segment. It is equidistant from both endpoints, and it is the centroid both of the segment and of the endpoints. It bisects the segment.
here, we have,
The points that are given to us are R(-2,3) and T(4, -2).
The point T is the mid point of the line segment RS.
If A(a, b) and B(c, d) are the two points then the mid point M of the two points will be,
M = ((a+c)/2), ((b+d/2))
So, using the above modified form of section formula we can find the coordinates of the point S.
Assuming point S to be x and y.
So, putting all the values,
(4, -2) = ((-2+x)/2), ((3+y/2))
Now, solving further, we get,
-1+x/2 = 4
-2+x = 8
x = 10
And,
3 + y = -4
y = -7
So, the coordinates are (10, -7).

Answer:
The answer is below
Step-by-step explanation:
We are asked to create a box plot. To create a box plot, we need to determine the minimum point, maximum point, lower quartile, upper quartile, interquartile range, median.
First we have to arrange the data in ascending order. This gives:
85, 150, 180, 200, 210, 250, 450
The minimum point = 85
The maximum = 450
[tex]Median=\frac{2}{4}(n+1)^{th}term=\frac{2}{4}(7+1)=4^{th}\ term=200\\\\Median=200 \\\\Lower\ quartile(Q_1)=\frac{1}{4}(n+1)^{th}term=\frac{1}{4}(7+1)=2^{nd}\ term=150\\\\Lower\ quartile(Q_1)=200 \\\\Upper\ quartile(Q_3)=\frac{3}{4}(n+1)^{th}term=\frac{3}{4}(7+1)=6^{th}\ term=250\\\\Upper\ quartile(Q_3)=250 \\\\Interquartile\ range=Q_3-Q_1=250-150=100[/tex]

Find the values of b such that the function has the given minimum value.
f(x) = x2 + bx − 21;
Minimum value:
−70
Answer: b = 14.
Step-by-step explanation:
We have the function:
f(x) = x^2 + b*x - 21
The minimum of a quadratic function will be at the vertex, and the vertex is at the value of x such that:
f'(x) = 2*x + b = 0
then the vertex is at:
x = -b/2
Then the minimum of the function f(x) will be:
f(-b/2) = (-b/2)^2 + b*(-b/2) - 21
and we know that the minimum value is -70, then:
f(-b/2) = -70 = (b^2)/4 - (b^2)/2 - 21
Now we need to solve this equation for b.
-70 = (b^2)/4 - (b^2)/2 - 21
-70 = -(b^2)/4 - 21
-70 + 21 = -(b^2)/4
49 = (b^2)/4
49*4 = b^2
196 = b^2
√196 = b = 14
The value of b is 14.

The perimeter of a rectangular field that measures 2 feet by 18 inches is _________ ft.
Answer:
7 ft
Step-by-step explanation:
As we know that the formula to find the perimeter of a rectangle is
P = 2 (l) + 2(w). With that being said, we can look at the question.
The answer should be given in terms of feet, so we will have to convert 18 inches to ft. In order to convert from inches to ft, you will have to divide by 12.
18 / 12 = 1.5ft
18 inches = 1.5 foot
Now we take the given values and put them into the formula to find the perimeter of the rectangular field.
2 (l) + 2(w) = 2 (2 ) + 2 (1.5) = 7ft
The perimeter of the rectangular field is 7ft.
