Answer: m=−3

Step-by-step explanation: −40−2(3m+1/2)=7m−2

−40+(−2)(3m)+(−2)(1/2)=7m+−2

−40+−6m+−1=7m+−2

(−6m)+(−40+−1)=7m−2

−6m+−41=7m−2

−6m−41−7m=7m−2−7m

−13m−41+41=−2+41

−13m/−13=39/−13

m=−3

What mistake I guess Keith did make is he subtracted 2 from -39 which equaled to -37 which caused him divide -37 by 13 when it should have been 39 divided by 13 because he should have left 39 alone and not have subtracted 2 from it also it should not have been negative basically what I'm trying to say is that he did his division and subtraction wrong.

Answer

The answer is negative 14.

Step-by-step explanation:

When you add a negative by a negative it equals a negative. Like if you add 1 + 1 it's going to equal 2 which is a positive, not a negative. So the answer is technically 8 + 6 which is 14 and all you have to do is add a negative sign.

If it's 18% for 9 months (and not per year)

then

1200x0.18=$216

If it's 18% per year then

Answer:

there is no any x

Step-by-step explanation:

but if you want to say -42x-3= -11

-42x-3+3= -11+3

-42x=8

-42x/-42=8/-42

x= -8/42

= -4/21

or if you want to say -42-3x= -11

-42+42-3x= -11+42

-3x= 31

-3x/-3=31/-3

x = -31/3

hope it's helpful ❤❤❤

Answer:

I think it is B

Step-by-step explanation:

=========================================================

Work Shown:

The smaller angles UVN and NVW add up to the largest angle UVW.

This is due to the angle addition postulate.

(angle UVN) + (angle NVW) = angle UVW

(6x+13) + (46) = 11+10x

6x + 59 = 11 + 10x

6x - 10x = 11 - 59

-4x = -48

x = -48/(-4)

x = 12

----------------

Extra info:

If you're curious about the angles, then we use that x value to find them

Note how 85+46 = 131 to show that (angle UVN) + (angle NVW) = angle UVW is a true equation. This confirms our answer for x.

Answer: 18ft

Step-by-step explanation: I took the quiz and got 100%

The height of the tree is 8.3 ft.

To solve this problem, we have to find the angle of elevation from the student.

To do this, we have to assume or bring out a right angle triangle and solve for the.

Given that we have the distance of A to F and the point  to F

Using trigonometric ratio,

We can find the tangent of this angle

[tex]tan\theta = \frac{opposite}{adjacent} \\tan\theta = \frac{6}{5}\\ tan \theta = 1.2\\\theta = tan^-^1(1.2)\\\theta = 50.2^0[/tex]

The angle of elevation can be calculated using sum of angles in a triangle is equal to 180 degrees

[tex]180 = 90 + 50.2 + x\\x = 180- 140.2\\x = 39.8^0[/tex]

Assuming a right angle triangle from the point the student is standing, the distance from him to the tree would be

[tex]15 - 5 = 10ft[/tex]

Let's use the tangent of the angle to find the height of the tree.

[tex]tan\theta = \frac{opposite}{adjacent} \\tan 39.8 = \frac{x}{10}\\x = 10 tan39.8\\x = 8.3ft[/tex]

From the calculations above, the height of the tree is 8.3 ft.

Answer:

y=4/5x-18/5

Step-by-step explanation:

there are multiple ways we can find the slope, let's use two points and the point slope form y=mx+b for this equation. we can find the slope by using the equation [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

in this case, we can use the two points (-3,-6), (2,-2)

y2=-2, y1=-6, x2=2, x1=-3

so, the equation is [tex]\frac{-2-(-6)}{2-(-3)}[/tex]

this reduces to 4/5

our slope is 4/5, so the equation for now is y=4/5x+b

let's use (2,-2) to find b. the y is -2, x is 2

-2=4/5(2)+b

-2=8/5+b, multiply both sides by 5:

-10=8+5b, subtract 8 from both sides

-18=5b, divide by 5

-18/5=b

our final equation is y=4/5x-18/5

Answer:

21

Step-by-step explanation:

It is given that two lines are parallel, and hence the corresponding angles are congruent, by corresponding angles postulate. It is also given that the triangles in the photo share an angle, by the reflexive property, the shared angle is congruent. Hence one can use angle-angle to determine that the two triangles in the picture are similar.

Using this, one can set up a proportion with the sides. The ratios of any two corresponding sides are the same as any other two corresponding sides in the triangle, respectively, this is due to the corresponding parts of similar triangles theorem.
