Both problems can be solved similarly since both shapes are Quadrilateral hence the sum of thier interior angels is 360
5.)
(x)+(x)+(4x-26)+(2x+18)=360
8x-8=360
x-1=45
x=46
6.)
(2x)+(x)+(x+10)+(2x-16)=360
6x-6=360
x-1=60
x=61
Answer:
4
Step-by-step explanation:
13.50 - 10.50 = 3.00
3 / 0.75 = 4
If the cyclist traveled 2/3 of his journey already, then the remainder would be 1/3 of his journey, which we know is 30 miles. Double that and we have the miles he traveled during the first 2/3, 60. Then divide 60 by the miles per hour, 12, to get 5 hours. Add in the 3 hours from the remaining 1/3 of the journey and you have your total; the cyclist's trip took 8 hours.
You will want to solve for where y=0.
-6x - 2(0) = -18.
-6x = -18
x = 3
The equation's x-intercept is at (3,0)
