Answer: 80°
Step-by-step explanation:
The sum of the angles in a triangle is 180°. Since the two angles of a triangle measure 15° and 85°.
The measure for the third angle will be:
= 180° - (15° + 85°)
= 180° - 100°
= 80°
The third angle is 80°
Answer:
<u>4 miles traveled</u>
Step-by-step explanation:
1.75 + 0.75m = 4.75.
4.75 - 1.75 = 3
3 ÷ 0.75 = 4
Answer:
-52
Step-by-step explanation:
-18+6=-12
-12-40=-52
Answer and explanation:
1. It is commonly referred to as the arithmetic average: the mean measure of central tendency is also referred to as the arithmetic mean or arithmetic average or just average.
It is algebraically defined (that is, there is an equation you can use to calculate its value): the mean can be represented by the algebraic equation
a1+a2+a3...ai/n
2. There can be more than one median where there are an even number of data points and not odd number, in which the two middle number are divided by 2
It can be found when there are undetermined scores: median can be found with undetermined scores
3. It corresponds to an actual score in the data: the mode is an actual value in the data that appears more frequently than other values
There can be more than one: there can be more than one mode(bimodal,trimodal,multimodal) where 2 or more values appear the same number of times
Answer:

Step-by-step explanation:
We can write the equation of a line in 3 different forms including slope intercept, point-slope, and standard depending on the information we have. We have two standard form equations which we will get a slope and a y-intercept from. We will convert each to slope intercept form to get the information. We will then write a new slope-intercept equation and convert to standard form.
3x-5y=7 has the same slope as the line. Let's convert.


The slope is
.
2y-9x=8 has the same y-intercept as the line. Let's convert.


The y-intercept is 4.
We take
and b=4 and substitute into y=mx+b.

We now convert to standard form.

For standard form we need the coefficients of x and y to be not zero or fractions. We need integers but the coefficient of x cannot be negative. So we multiply the entire equation by -5 to clear the denominators.
