b=3a so put 3a for every b
c=5a so put 5a for every c
a+3a+5a=180
9a=180
divide 9 both sides
a=20
b=3a
b=3(20)
b=60
15% of 1085/6 =
15/100 * 1085 6/10 =
= 15/100 * 10856/10 =
= 3/100 * 10856/2 (after simplifying numerator of 15 and denominator of 10)
= 3/100 * 5428 =
= 16284/100 =
= <u>162,84</u>
Answer: 15% of 1085.6 is 162,84 (it's correct - I doublechecked it with calculator)

Answer:
<u>The number is 296.</u>
Step-by-step explanation:
Let's call "x" to the number we are looking for.
Now, the problem states that "5 more than the quotient of a number and 8 is 42". This means that this number is being divided by 8, it's also being additioned 5 and the final result is 42. Therefore, the expression of this operations on this number is the following:
. Let's solve the equation to find x.
1. Write the expression.

2. Substract 5 from both sides and simplify.

3. Multiply 8 on both sides and simplify.

<u>We have found our number, it's 296!</u>
