Find the value of X.

Answers

Answer 1

The sum of every triangle is 180, by Tales Theorem.

x + (x + 28) + 78 = 180

2x + 28 + 78 = 180

2x + 106 = 180

2x = 180 - 106

2x = 74

x = 74/2

x = 37

23. Starting with x=0.81818181 , express x as a fraction in simplest form.

Answers

You could do x=81 with the little line on the top (represents the number going on forever, and example is 0.818181818181818181818181818818181818 etc.)

The repeating decimal 0.81818181 as a fraction is 9/11

Converting the repeating decimal to a fraction.

From the question, we have the following parameters that can be used in our computation:

x = 0.81818181

Write out the first two digits

Number = 0.81

Express as fraction

So, we have

Number = 81/100

Subtract 1 from the denominator

Number = 81/99

Simplify

Number = 9/11

Hence, the fraction is 9/11

Answer:

Part A: The equations are:

y = -1/2x + 2, and

y = 3x - 5

Part B: The solution is (2,1)

Step-by-step explanation:

Part A: There are two equations we need to find, each line is the graph of a function.Graphs are written in y = mx + b, m is the slope, which is the change in y divided by the change in x, and b is the y - intercept. To find the function of the first graph, the one going slightly down, the slope is: y goes down by one, and x increases by 2, so change in y/ change in x is -1/2. The y - intercept is where the graph goes through the point where x is 0, on this graph, the point is (0,2), the y - intercept is 2, so y = mx + b is y = -1/2x + 2

For the other equation, slope is when y increases by 3, x increases by 1, so 3/1, or 3. The y - intercept is -5, so y = 3x + (-5), or y = 3x - 5

Part B: The solution to this equation is the point where both of the functions meet, here, this point is (2,1), y is 2 and x is 1.

B. 42 – (5 ? 2)
C. (42 ÷ 2) – 5
D. (42 ÷ 2) + 5

Answers

It should be D.

“Mr. Roberts drive five miles more than half the distance he drove on Monday”

Five miles more is key here

This says that he drove five more after dividing it, so 42/2 first than add the 5
