Answer:
1 milliliter is 20 drops.
So since angle A is 120, so angles B+C=60 because there are 180 degrees in a triangle. So B:C is 2:1. So angle B is 40 and angle C is 20.
3/8 + 1/8 = 4/8 = 1/2
therefore the plant grew 0.5 or 1/2 in.
Answer:
Your solution is 21 = x.
Step-by-step explanation:
This problem involves two fractions. The LCD is 6. Mult. both sides of this equation by 6 to obtain 2(x+6) = 3(x-3).
Performing the indicated multiplication, we get 2x + 12 = 3x - 9.
Combining like terms: 21 = x
Answer:
x = -25/3
Step-by-step explanation:
Start with the given equation: (-3/5)x + 2 = 7.
We must isolate x. Here we have 2 added to (-3/5)x; the inverse operation would be subtraction of 2 from both sides. This results in:
(-3/5)x = 5.
Now, in (-3/5)x, we have division by 5. The inverse of division is multiplication. So, we multiply both sides of (-3/5)x = 5 by 5, obtaining
-3x = 25.
We want x alone. Here x has been mult. by -3. The inverse op. would be division of -3x = 25 by -3.
Performing this division, we get x = -25/3.
