Answer:

40

Step-by-step explanation:

The angles are vertical angles so they equal each other.

So 3x=120 divide each side by 3 to get x by itself

So x is 40

3x and 120 are both vertical degrees.

Essentially, vertical degrees are two angles that are on the exact opposite sides. These vertical degrees are always congruent.

Since 3x and 120 are congruent, we can make an equation to solve for x:

3x = 120
Divide:
x = 40

Let me know if you need any further explanation :)

Solve for www. Give an exact answer in simplified form. 53w+13 < 56w + 16
ki77a [65]

The solution will be:  w>-1

<em><u>Explanation</u></em>

The given inequality is:   53w+13 < 56w + 16

First we will subtract 56w from both sides. So.....

53w+13-56w

Now we will subtract 13 from both sides. So.....

-3w

Then we need to divide both sides by -3. As here we are <u>dividing the inequality by a negative number, so we need to switch the inequality symbol</u>. So, we will get.......

\frac{-3w}{-3}>\frac{3}{-3}\\ \\ w>-1

Thus, the solution will be:  w>-1

It took Brian 6 hours to drive to the sales conference. He took the same route on the way back home, but
g100num [7]

Answer:  54 mph

Step-by-step explanation:

d-the distance

s+9  -  the speed to the conference

d=6*(s+9)

s- is the speed on the way back home

d=7*s

so    6*(s+9)=7*s

       6s+54=7s

     -6s          -6s

       54= 7s-6s

       s=54  mph

Ivenika [448]

cos(30)=x/8

Rewrite the equation as

x/8=cos(30)

Multiply both sides of the equation by

8

.

8

⋅

x/8=8⋅cos(30)

Simplify both sides of the equation.

Tap for more steps...

x=4√3

The result can be shown in multiple forms.

Exact Form:

x=4√3

Decimal Form:
