Answer: x = -3
Step-by-step explanation:
i simply divided by -7, in order to get x by itself.
-7/-7x = 21/-7
that cancels out the -7 on the left side, and leaves us with -3 on the right side!
x = -3
F(x) - g(x) =
x^1/2 - (2x^3 - x^1/2)=
x^1/2 - 2x^3 + x^1/2=
2x^1/2 - 2x^3
Answer:
28 Kg : 8 Kg
Step-by-step explanation:
Sum the parts of the ratio, 7 + 2 = 9 parts
Divide 36 Kg by 9 to find the value of one part of the ratio.
36 Kg ÷ 9 = 4 Kg ← value of 1 part of the ratio, thus
7 parts = 7 × 4 Kg = 28 Kg
2 parts = 2 × 4Kg = 8 Kg
36 Kg in the ratio 7 : 2 = 28 Kg : 8 Kg
Answer:
y = 
Step-by-step explanation:
Given
y + v = s ( subtract v from both sides )
y = s - v
Multiply through by 3 to clear the fraction
2y = 3s - 3v ( divide both sides by 2 )
y =
