Answer:
The answer to your question is 24 cm³
Step-by-step explanation:
Data
Initial volume = 2/5
Additional volume = 42 cm³
Final volume = 4/7
the total volume of the glass = ?
Process
1.- Write a proportion to help you solve the problem
42 cm³ -------------------- 4/7 of the total
x ------------------- 7/7
2.- Solve the proportion
x = (7/7 x 42) / 4/7
3.- Simplification
x = 42 / 4/7
x = 168/7
x = 24 cm³
First divide both sides by 5. Then you get the answer. -0 or 0 I'm not sure tho
Answer:
x = 1.5
Step-by-step explanation:
-1.2 (3 - x) = -1.8
<em>Apply distributive property</em>
-3.6 + 1.2x = -1.8
<em>Get 1.2x alone so add -3.6 to each side</em>
1.2x = 1.8
<em>Get x alone so divide 1.2 on each side</em>
x = 1.5
Hope this helps!
