Answer:
x = 22, y = 22/7
Step-by-step explanation:
solve for y using first equation:
-2 + 3y = 20
3y = 22
y = 22/7
substitute 22/7 into second equation:
7y = x
7(22/7) = x
x = 22
You use Volume equation for a cone. Then you plug ur given numbers into that equation.
As always, the sum of the measures of the angles in a triangle is 180°.
(x -5) +(3x +30) +35 = 180
4x +60 = 180 . . . . . . . . . . . . . collect terms
4x = 120 . . . . . . . . . . . . . . . . . subtract 60
x = 30 . . . . . . . . . . . . . . . . . divide by 4
a) The value of x is 30.
C. You multiply 5 x e and form together as 5e.
