Answer:
y = 2 / (r/3 - s/5)
Step-by-step explanation:
r/3 - 2/y = s/5
add 2/y to both sides
r/3 = s/5 + 2/y
Subtract s/5 from both sides
r/3 - s/5 = 2/y
multiply both sides by y
y(r/3 - s/5) = 2
Divide both sides by r/3 - s/5
y = 2 / (r/3 - s/5)
The whole melon = 5/5
ONE piece went to four children, so
how much of the melon the children got = 1/5
5/5 - 1/5 = 4/5
With 4/5 of the melon, she made 3 fruit cups
4/5 / 3 = 4/5 x 1/3 = 4/15
so she put 4/15 of the melon in the fruit cups
To find the inverse of a function, switch the x's and y's, then solve for y again.
y = 2/3x - 17
SWITCH
x = 2/3y - 17
2/3y = x + 17
y = 3(x + 17) / 2
y = x - 10
SWITCH
x = y - 10
y = x + 10
y = cuberoot(2x)
SWITCH
x = cuberoot(2y)
x^3 = 2y
y = x^3 / 2
y = x/5
SWITCH
x = y/5
y = 5x
Hope this helps!
Answer:
13
Step-by-step explanation:
Step-by-step explanation:
C) 5x + 13x = 180°
Because, the angles in the diagram add up to 180° because it's a straight angle
So, the sum of both of them will give 180
So option (C) is right
