Answer:
Kim is 20 years old
Step-by-step explanation:
We have to make equations;
Kim= laura+10 so L+10
Laura is twice as old as Melissa so Laura will be
2 X M = 2M
<h2>Melissa is 5 years old now </h2>
Input values in to the equation
<h2>2M = 2X5= 10 years old (Laura)</h2>
As Kim is 10 years older than Laura it will be 10+10
<h3>which will give the answer of
20 </h3>

Answer:
Step-by-step explanation:
Ratio is an expression that shows the relationship between two items in terms of quantity. It shows how much of one item can be found in another.
Simon used 3 pears and 9 apples to make a fruit salad.
This is expressed in terms of quantity.
The ratio of the number of pears which simon used to the number of apples which simon used will be
Number of pears which simon used ÷ the number of apples which simon used.
The ratio is 3/9.
Simplifying further to its lowest term,
It becomes 1/3
This is done by dividing the numerator and denominator by 3
The number which divides any other numbers
Your equation is presented in by the following formula of y = mx + b
m = slope, it is the coefficient of X
y = 4/5 X - 3
m = 4/5
