Is there more to the question?
It’s definitely-20
Add 9 to both sides to cancel it out so it is now
4x-20=5x
Than subtract 4x on both sides it is now
-20=x
Because 5-4 equals 1 and 1x is just written as x
Answer:
6/95.
Step-by-step explanation:
Prob(red marble on the first choice) = 4/(10+6+4)

= 1/5 * 6/19
= 6/95.
Hello! To solve this problem, all you have to do is add and subtract numbers as needed.
A. An expression for this would be 0.85 + 0.50 + 0.15 - 0.30. This is because there is already juice in the mixture. Celina adds more juice in it and she drinks some of it.
B. Now, let’s solve the expression. 0.85 + 0.50 is 1.35. 1.35 + 0.15 is 1.5. 1.5 - 0.3 = 1.2. The amount of juice left in the jar is 1.2 liters.
