If the probability of picking a red marble out of the total 63 is 8/9, then it's reasonable to think that 8/9 of the total number of marbles must be red. So there are likely 8/9 × 63 = 56 red marbles in the bag.

lord [1]

Answer:

Paul's salary is increased by 6% and John's salary is 2 more than thrice Paul's salary.

Step-by-step explanation:

Paul and John are working in a Company and this month Paul's salary is increased by 6%. John's salary is 2 more than thrice Paul's salary.

If <em>x </em>represents Paul's salary before increment, and <em>y</em> represents John's current salary, find Paul's current salary.

<em>x </em>is Paul's salary before increment.

So, Paul's current salary = <em>x</em> + 6% of <em>x</em>

= <em>x</em> + 0.06<em>x</em>

= 1.06<em>x</em>

John's current salary is 2 more than thrice Paul's salary.

So, John's current salary = 3(1.06<em>x</em>) + 2.

Solve the equation s + 2.8 = 6.59
Contact [7]
S + 2.8 = 6.59
s = ?

To solve for s use the inverse operation of addition, which is subtraction.

s + 2.8 = 6.59
6.59 - 2.8 = s
6.59 - 2.8 = 3.79
s = 3.79

Check:

s + 2.8 = 6.59
s = 3.79
3.79 + 2.8 = ?
3.79 + 2.8 = 6.59
Correct!

This proves: s = 3.79 ;)
