The answer is 70 my good fellow
Let Poly = X
Andy gets twice as much as Poly so Andy = 2X
Pheobe gets three times as much as Andy, so she is 3(2x) = 6X
Now add them together to equal 270:
X + 2X + 6X = 270
Simplify:
9X = 270
Divide both sides by 9:
X = 270 /9
X = 30
Poly = X = 30
Andy = 2X = 2(30) = 60
Pheobe = 6X = 6(30) = 180
Answer:
5x - 2y = 20
Step-by-step explanation:
Find x-intercept by substituting y for 0
5x - 2y = 10
5x - 2(0) = 10
Isolate x to get x-intercept.
5x = 10
x = 2
(2, 0)
Twice of this intercept is (4,0).
Find y-intercept by substituting x for 0
5x - 2y = 10
5(0) - 2y = 10
Isolate y to get y-intercept.
-2y = 10
y = -5
(0, -5)
Twice of this intercept is (0, -10).
A line should have the y-intercept -10 and x-intercept 4.
In original equation, double the 10.
Test for x and y intercepts.
5x - 2y = 20
-2y = 20
y = -10
5x - 2y = 20
5x = 20
x = 4
An equation is 5x - 2y = 20.
Cube root of 27 a^12 will be: 3 a^4.
