To find the quotient (division) multiply by the reciprocal. The reciprocal of 1/3 is 3.
She has 45% of the original amount left
<h3>Ratio and proportions</h3>
Fractions are written as a ratio of two integers
Given the following
Initial amount. = ∈4000
Amount given to her sister = 1/4 * 4000 = 1000
Amount given to her brother = 40% of 3000 = 1200
Amount left = 4000 - (1000+1200)
Amount left = ∈1800
Determine the percentage left
x * 4000 = 1800
x = 1800/4000
x = 0.45
x = 45%
Hence she has 45% of the original amount left

The slope of the equation would be 7/3 since the original slope was -3/7. We already know y int (b) so the eqn is
y = 7/3x + 2
Answer:
18
Step-by-step explanation:
To find the number, write an algebraic equation with the given information. Let the variable n represent the unknown number.
Now, break it by parts - "three times a number" would be 
. The "is" means that it equals something, giving us 
. "36 less than 5 times the number" would be subtracting 36 from whatever 5 times the number is: 
. So, put it all together and it is 
.
Next, solve the equation for n. The answer will be the number.
Thus, the number is 18.
Answer:
y=a(b)^x
y=0.01(3)^x
a is start, b is multiplier
