Answer:
12
Step-by-step explanation:
Assume the hidden number is x;
So, if x*12= 16,836
Next, divide both sides by 12 to solve for x;
x= 16,836 / 12
x= 1,403
So the number hidden by spilt ink is 1,403.
Next, to answer the question, divide 16,836 by the hidden number,1403;
16,836 / 1403 = 12
Therefore, it will be equal to 12 which is basically the reverse of the first equation.
The measurement of angle C is 228°
Answer:
5%
Step-by-step explanation:
Lets say 10 add a 0 = 100 9.5 add a 0 = 95.0 (move ok decimal place) so there is a 5% error.
Answer:
x = 25 cm
Step-by-step explanation:
a² + b² = c²
20² + 15² = c²
400 + 225 = c²
625 = c²
√625 = c
25 = c
If 2a−b/6 = b/3, then ratio a:b = 3 : 2
<h3><u>Solution:</u></h3>
Given that 2a−b/6 = b/3
We have to find the ratio of a:b
In mathematics, a ratio indicates how many times one number contains another
A ratio between two or more quantities is a way of measuring their sizes compared to each other
let us first solve the given expression

On cross multiplication we get,
6a - 3b = 6b
6a = 6b + 3b
6a = 9b

To convert a fraction to a ratio, first write down the numerator, or top number. Second, write a colon. Thirdly, write down the denominator, or bottom number
Therefore ratio a:b = 3 : 2
