find the values of x and z.
Answer:
z=72
x=6
Step-by-step explanation:
you have the value of z=72 because of the fact that if you take 2 intersecting lines the angles on either side are always equal.
(360-(72+72))/2=12x+36
216/2=12x+36
108=12x+36
take away 36 from either side
72=12x
divide each side by 12
x=6

Solve for n. -4n + 7 = 1 – 2n
Answer:
n = 3
Step-by-step explanation:
subtract 1 from both sides to get:
-4n + 6 = -2n
then add 4n to both sides to get:
6 = 2n
then divide both sides by 2 to get:
3 = n

Part A: Create at a system of liner equations with no solutions. In two or more complete sentences explain the specific characteristics that you have include in each equation to ensure that the system would not have a solution.
Part B: Using one of the equations that you created in part A create a system of liner equations that has one solution (x y)use substitution to solve the system.
A system of linear equations with no solution means that the lines never meet. So as long as your two lines have the same slope and different intercepts, they will be parallel.
Ex.) y= 2x + 5
and y=2x + 10
to have a solution, the lines have to cross at a point. so literally any two lines that aren't parallel.
Ex.) y= 3x + 1
to find the solution you start by setting the equations equal to each other
2x + 5 = 3x + 1
1) subtract 2x from both sides
5= x + 1
2) subtract 1 from both sides
4 = x
now we know the x value of the point is 4. To find the y value plug 4 into one of the equations
2(4) + 5
8 + 5
13
so the solution to this particular system is (4,13)

The area of square C is 100 square units and the area of square B is 64 square units. What would be the area of square A?
Answer: The area of square A is 28 square units because the area is decreasing by 36 and the angles on each side is decreasing by 9
Step-by-step explanation:
100 divide by 4 sides = 25
64 divide by 4 sides = 16
28 divide by 4 sides = 7

Evaluate: log6 1,296
Answer:
4
Step-by-step explanation:
Using the rule of logarithms
[tex]log_{b}[/tex] x = n ⇒ x = [tex]b^{n}[/tex] then
let [tex]log_{6}[/tex] 1296 = n
1296 = [tex]6^{n}[/tex] = [tex]6^{4}[/tex] , thus
n = 4

How many calendars did the 1st and 2nd period classes sell on average per week? Write and solve a multiplication equation.
Answer:
About 27 calendars per week
Step-by-step explanation:
I dived 60 by 7 because there are 7 days in and week and got 8.5 which I round up by 9. I did the same with 123 and got 17.5 which I round up to 18. By adding them together, they sell 27 averagely per week.
Hope this Helped
The average number of calendars sold in the 1st and 2nd periods is 91.5.
What is a mean?It is the average value of the set given.
It is calculated as:
Mean = Sum of all the values of the set given / Number of values in the set
We have,
Number of calendars sold in 1st period = 60
Number of calendars sold in 2nd period = 123
The average of calendars sold in the 1st and 2nd periods.
= (60 + 123) / 2
= 183/2
= 91.5
Thus,
The average number of calendars sold is 91.5.

STU is an equilateral triangle. If ST is one less than twice x, SU is 37 less than five times x, and TU is 11 more than x, find x and the measure of each side.
Answer:
x = 12Side = 23 unitsStep-by-step explanation:
STU is an equilateral triangle. And:
ST = 2x - 1SU = 5x - 37TU = x + 11All sides are equal. Then take one pair and solve for x:
2x - 1 = 5x - 373x = 36x = 12Substitute x to find the side length:
2x - 1 = 5x - 37 = x + 11 = 23please answer!!
