Evaluate when x = 2 and y = 5:
2 + (12 - 5x): 2g
Just substitute x = 2 and y = 5 into the equation wherever you see x and y.
2 + (12 - 5x) · 2y
2 + (12 - 5(2)) · 2(5)
2 + (2) · 10

Equation #1: 3x + 6 = x - 24
Equation #2: 10 – 2m = 16
Answer:
x = -15
m = -3
Step-by-step explanation:
3x + 6 = x - 24
subtract the x from both sides to make the unknown variable on only one side of the equation
2x + 6 = -24
subtract the 6 from both sides to focus on the x
2x = -30
now divide both sides by 2 to get the x by itself
x = -15
that's your answer
10 - 2m = 16
subtract the 10 from both sides to focus on the m
-2m = 6
now divide both sides by -2 to get the m by itself
m = -3
that's your answer
A submarine descends to -100 feet in 2 minutes and -250 feet in five minutes. Write and solve an equation to find the depth of the submarine in 8 minutes.
Answer:
-400
Step-by-step explanation:
So, to find what the depth would be in 8 minutes, you have to find the depth for ONE minute. So, you divide -100 by 2 and you get -50 in a minute. Next thing you do is you multiply -50 by 8. You get -400. And there's your answer!

Len bought 12.3 ounces of cashews and 15.2 ounces of almonds.
He calculates that if he and four friends share all the nuts equally,
each person will receive 5.1 ounces of nuts.
Which is the best explanation for whether or not his answer is reasonable?
A. Not reasonable; 12.3 + 15.2 = 25.5 and 25.5 ÷ 5 = 4.5.
B. Not reasonable; 12.3 + 15.2 = 27.5 and 27.5 ÷ 5 = 5.5.
C. Reasonable; 12.3 + 15.2 = 27.5 and 27.5 ÷ 5 = 5.1.
D. Reasonable; 12.3 + 15.2 = 25.5 and 25.5 ÷ 5 = 5.1.
Answer:
B
Step-by-step explanation:
Total ounces of nuts is cashews (12.3 ounces) plus almonds (15.2 ounces) is 27.5 ounces. If you divide 27.5 ounces by 5 people, 27.5 / 5 = 5.5 ounces each.
10+4x = 5(x−6)+ 33
solve for x
Answer:
X=7
Step-by-step explanation:
10+4x=5(x-6)+33
1. Distribute the 5 to both the x and the 6
10+4x=5x-30+33
2. Subtract 4x from 5x ( should be left with 1x but just write x)
10=x-30+33
3. add 30 to both sides (whole number on the left, x on the right)
40=x+33
4. Subtract 33 on both sides
7=x (flip it around)
x=7

Using the figure to the right, if RSTU is a rhombus, find measure RST.
Given:
In rhombus RSTU, [tex]m\angle RUV=(10x-23)^\circ[/tex] and [tex]m\angle TUV=(3x+19)^\circ[/tex].
To find:
The [tex]m\angle RST[/tex].
Solution:
We know that, diagonals of a rhombus are angle bisector. So,
[tex]m\angle RUV=m\angle TUV[/tex]
[tex](10x-23)^\circ=(3x+19)^\circ[/tex]
[tex]10x-23=3x+19[/tex]
Isolating variable terms, we get
[tex]10x-3x=23+19[/tex]
[tex]7x=42[/tex]
Divide both sides by 7.
[tex]x=\dfrac{42}{7}[/tex]
[tex]x=6[/tex]
Now,
[tex]m\angle RUV=(10x-23)^\circ[/tex]
[tex]m\angle RUV=(10(6)-23)^\circ[/tex]
[tex]m\angle RUV=(60-23)^\circ[/tex]
[tex]m\angle RUV=37^\circ[/tex]
And,
[tex]m\angle TUV=(3x+19)^\circ[/tex].
[tex]m\angle TUV=(3(6)+19)^\circ[/tex]
[tex]m\angle TUV=(18+19)^\circ[/tex]
[tex]m\angle TUV=37^\circ[/tex]
Now,
[tex]m\angle RUT=m\angle RUV+m\angle TUV[/tex]
[tex]m\angle RUT=37^\circ+37^\circ[/tex]
[tex]m\angle RUT=74^\circ[/tex]
We know that opposite angles of a rhombus are equal.
[tex]m\angle RST=m\angle RUT[/tex]
[tex]m\angle RST=74^\circ[/tex]
Therefore, the measure of angle RST is [tex]74^\circ[/tex].

khan acadeny
Answer: 30 Pins
Step-by-step explanation:
I solved it on khan academy
Subtracting their means, it is found that the mean of D is of 30.
When two variables are subtracted, the mean is the subtraction of the means, while the standard deviation is the square root of the sum of the variances.In this problem, the means of the variables are:
[tex]\mu_B = 610, \mu_A = 640[/tex]
Since D = A - B, the mean of D is:
[tex]\mu_D = \mu_A - \mu_B = 640 - 610 = 30[/tex]
The mean of D is of 30.

Consider the polygons, Name a series of transformations that will take AABC to AA'B'C'.
What do we need to know about the triangles to show that they are congruent?
Answer:
A. The triangle in quadrant 2 will reflect over the y axis onto quadrant 1 and then slide over the x axis to quadrant 4.
B. Congruent means same shape and same size. So congruent has to do with comparing two figures, and equivalent means two expressions are equal. So to say two line segments are congruent relates to the measures of the two lines are equal. So basically triangles are congruent when they have the same shape and size. So if you have two triangles and you can transform (for example by reflection) one of them into the other (while preserving the scale), the two triangles are congruent.
If you flip/reflect MNO over NO it is the "same" as ABC, so these two triangles are congruent.
You need to find the SSS, AAS, ASA, SAS
Step-by-step explanation:
SSS: When all three sides are equal to each other on both triangles, the triangle is congruent
AAS: If two angles and a non-included (you can think of it as outside) side of one triangle are congruent to the corresponding parts of another triangle, then the triangles are congruent.
ASA: If two angles and the included side of one triangle are congruent to the corresponding parts of another triangle, then the triangles are congruent.
SAS: If any two angles and the included side are the same in both triangles, then the triangles are congruent.

The circular opening of a tunnel has a circumference of 42 meters. Which equation can be used to find d, the diameter of the tunnel opening?
The equation that can be used to find d, the diameter of the tunnel opening, is: d = 42/π
What is circumference ?
The circumference is the distance around the outer edge of a closed, circular object such as a circle or a sphere. It is the length of the boundary of the circle or sphere, and is usually measured in units of length, such as centimeters, meters, or feet.
The formula for the circumference of a circle is:
C = 2πr
where C is the circumference, π is a mathematical constant approximately equal to 3.14, and r is the radius of the circle.
In this problem, we are given the circumference of the tunnel opening, which is 42 meters. We want to find the diameter of the tunnel opening, which is twice the radius. Therefore, we can use the following equation:
C = 2πr = πd
where d is the diameter of the tunnel opening.
We can rearrange this equation to solve for d:
d = C/π
Substituting the value of C = 42 meters, we get:
d = 42/π meters
Therefore, the equation that can be used to find d, the diameter of the tunnel opening, is: d = 42/π
