1. 1. Points A and B are to be mapped onto a number line according to two equations. The solution to the equation is the coordinate of point A. The solution to the equation is the coordinate of point B.
(a) Solve the first equation to find the coordinate of point A. Show your work.
(b) Solve the second equation to find the coordinate of point B. Show your work.
(c) Determine the distance between points A and B. Explain.

2. 2. Kim is x years old. Jordan is 7 years older than Kim. Four times Jordan’s age is equal to 200.
(a) Write an equation that could be used to solve for Kim’s age, x.
(b) How old is Kim?
(c) How old is Jordan?

3.3. Solve the given inequality and graph the solution on a number line.

please help

94

step-by-step explanation:

average the numbers and use a variable to figure out the minimum to get a 90.

(79+94+91+92+x)/5=90

x = 94

explanation:

remove parenthesis:

=

apply rule

=

multiply fractions:

divide:

=

mordancy.

the degrees would remain the same ( the number to the left of the decimal point.

the multiply the decimal by 60 to get the minutes and use the numbers to the left of the decimal point.

then multiply the decimal portion of that by 60 for the seconds and round off as needed.

39 .956652

the 39 remains the degrees.

the minutes = 0.956652 x 60 = 57.39912

the minutes = 57

the seconds = 0.39912 x 60 = 23.95 = 24 ( rounded to nearest tenth)

so 39.956652 = 39 degrees, 57 minutes and 24 seconds

-75.159809

the -75 remains the degrees

the minutes = 0.159809 x 60 = 9.58854

the minutes = 9

the seconds = 0.58854 x 60 = 35.31, rounded to nearest tenth = 35.3 seconds

so -75.159809 = -75 degrees, 9 minutes and 35.3 seconds.

the first coordinate is north or south, since it it positive it is north.

the second number is east or west, because it is negative it is west.

39 degrees, 57 minutes and 24 seconds n

-75 degrees, 9 minutes and 35.3 seconds w
