We can use the vertical angle theorem which states that any two opposite angles are congruent. So, you can just set the two measures equal to each other and solve for x:
7x-99=2x+1
5x-99=1
5x=100
x =  \frac{100}{5} = 20

So, your answer is 20°.

-(-(-)(-)(-10x))=-5 solve for x
ElenaW [278]
-(-(-)(-)(-10x)) = -5

We need to cancel out the negatives, so we need to simplify this.

To make things a bit easier for you, we can begin by counting out how many negatives we have. After counting, you should have a negative number count of 5. However, one of the negatives is apart of (-10x) so we'll have 4 negatives and then an extra negative in with 10x.

Remember that "-" could also be looked at as "-1."

So, if we break this down into smaller parts and substitute "-" into "-1," then this'll look like this :

-1 × -1 × -1 × -1 × (-10x) = -5

Remember that a negative times a negative is always a positive.

So, since there are four negatives, then you just multiply it all together.

This results in 1 × (-10x) = -5

Simplify.

-10x = -5

Now, you simply divide both sides by -10.

-10x ÷ -10 = -5 ÷ -10

Simplify.

x = 1/2

The Sears tower in Chicago is 1450 feet high. A model of the tower is 24 inches tall. What is the ratio of the height of the mod
miskamm [114]

The ratio of the model's height to actual height of tower is 1:725

Step-by-step explanation:

Given

Actual height of Sears Tower = H_a = 1450 feet

Height of Model = H_m = 24 inches

We can divide the actual height by the model's height to find the scale

Let z be the ratio of the height of the model to the actual height

z = \frac{H_m}{H_a}\\z = \frac{24\ inches}{1450\ feet}\\z = \frac{12\ inches}{725\ feet}

The ratio should be in same unit.

We know that

1 ft = 12 inches

Then

z = \frac{1}{725}\\z=> 1:725

Hence,

The ratio of the model's height to actual height of tower is 1:725

If the function 5x + y = 1 has the domain {-2, 1, 6}, then what is the corresponding range?
inysia [295]

Answer:

{ 11, -4, -29}

Step-by-step explanation:

5(-2) + y = 1

-10 + y = 1

y = 11

5(1) + y = 1

y = -4

5(6) + y = 1

30 + y = 1

y = -29
