Answer:
x= 3
y = 0
Step-by-step explanation:
•Add the two equations to cancel out +6x and -6x
•Find the value of y
•Substitute the value of y into equation 1 to find the value of x.
Hope I was able to help you:)
Ok so for the first one:
-We know that the 4 angles add up to 360
-3 of the angles are given
-To find the fourth we simply subtract the sum of the 3 angles from 360.
Equation: 120+ 100+ 100 + x = 360
= 320+x= 360
Now by making x the subject
x= 360 - 320
= 40 degrees
The second one follows the same method
150+ 77+ 48+ x =360
275 +x = 360
x= 360-275
x= 85
Answer:
110.2
Step-by-step explanation:
if a = 1, b = 2, c = 3, d = 4, and e = 5
find the volume for all the shapes
The post
V = lwh = (1)(1)(2) = 2
The bottom of the mailbox
V = lwh = (3)(4)(5) = 60
The top of the mailbox
V = πr²h = (3)(5)π = 15π = 48.2
Then add them all together:
2 + 60 + 48.2 = 110.2 is the total Volume
Table A(the top one) had a proportional relationship hope this helped
