Bonjour!
90% de 2300=2070
112% de 80= 100% de 80 + 12% de 80 = 89.6km/h
:)
We have the following:
solving for x
The solution of x is equal to 28, therefore 12 is not a solution of the equation
5x = 4y - 3
Standard form is Ax + By = C, so first subtract 4y to both sides:
5x - 4y = -3
Answer:
C) 6 inches
Step-by-step explanation:
Given function:
The function compares plant height in inches to the age of plant in weeks.
So, we can say
represents height of plant in inches.
represents age of the plant in weeks.
In order to predict the height of the plant in 5 weeks, we will plugin 
in the given function and evaluate
⇒ 
⇒ 
⇒ 
inches
Thus the approximate height of plant in 5 weeks would be 
inches
When finding the percent difference between two numbers, there are two ways you can do this.
1. The first way is how to calculate the percentage INCREASE of two numbers:
-The formula is Increase / Original Number × 100 = % increase
Step 1: Find out the difference between the two numbers you're comparing. New number - Original number = Increase.
Step 2: Divide the increase by the original number and then multiply your answer by 100. (If your answer is a negative number, then it is a percent decrease, not a percent increase.)
2. The second way is how to calculate the percentage DECREASE of two numbers:
Step 1: Find out the difference between the two numbers you're comparing. Original number - New number = Decrease.
Step 2: Divide the decrease by the original number and then multiply your answer by 100. Decrease ÷ Original Number × 100
= % Decrease. (If your answer is a negative number, then is is a percent increase, not a percent decrease.)
