Answer: x° is 50°
Step-by-step explanation: The sum of the exterior angles of a polygon is 360.
Add the given exterior angles:
35+50+20+125=230
to find the missing exterior angle, supplementary to x°,
Subtract 360 - 230 = 130
The Sum of Supplementary angles is 180°
x° + 130° = 180°
x = 50
Answer:
4 (-1-11) + 2 (17)
Answer 2 is -14
Step-by-step explanation:
The blue dot is equal to -5
Remember yo can do anything to an equation as long as you do it to both sides
so
remember distributive property
a(b+c)=ab+ac
so first distribute
2(3x)+2(-9)=18x
6x-18=18x
minus 6x both sides
-18=12x
divide both sides by 12
-18/12=x
-9/6=x
-3/2=x
easier way is to first divide both sides by 2
x=-3/2
(a) If we let x be the number of miles and y be the total cost, the equation for relating the number of miles and the total cost would be,
y = 0.4x + 48
(b) If the rental cost is 60,
60 = 0.4x + 48
The value of x from the equation is 30.
(c) You may prepare the table of values by allowing x be any number and then solve for y until we arrive with an answer for y being equal to 60.
