lets represent the miles she will go per hour by x

240=×

5=1hour

with cross multiplication,= 240×1hour=5×x

240=5x

divide both sides by 5

240/5=5x/5

48=x

hence x=48

Two complementary angles are represented by x and x+14 . find the value of x

qaws [65]

Answer:

$x=38\textdegree$

Step-by-step explanation:

Remember that complementary angles <em>always </em>add up to 90°.

We know that the two complementary angles are represented by (x) and (x+14). In other words:

$(x)+(x+14)=90$

So, let's solve for x.

First, combine like terms:

$2x+14=90$

Let's isolate the x by subtracting 14 from both sides:

$(2x+14)-14=(90)-14$

The left cancels. Subtract on the right:

$2x=76$

Divide both sides by 2:

$\frac{2x}{2}=\frac{76}{2}$

The left side cancels. Divide on the right:

$x=38\textdegree$

So, the value of x is 38°.

And we're done!

Asap help me pleaseeeeee

Nastasia [14]

The equation would be

8 = 6x + 2

the “number” is unknown, so it’s x.
6 times the number would be 6x.
The sum of 6x and 2 means adding together 6x and 2, so 6x + 2
And it’s supposed to equal 8

15. Find the value of x.<br> (68 - x)<br> 3x

masha68 [24]

Answer:

17=x

Step-by-step explanation:

In this case, we need to use Vertical Angles Theorem to solve this problem. Basically, because of the position of the angles, they are congruent.

68-x = 3x

Add x to both sides

68=4x

Divide by 4

17=x

Hope this helps!
