Answer:
No they are not; rectangles are only similar if there is a consistent ratio between all sides. An example of two rectangles that are similar would be a rectangle with dimensions of 2 x 7 and another one with dimensions of 4 x 14.
You are told Y is the number of large vehicles washed and that there were 50 large vehicles.
Replace Y with 50 in the given equation to solve for x ( the number of small cars.
5x + 10(50) = 800
5x + 500 = 800
Subtract 500 from both sides:
5x = 300
Divide both sides by 5:
x = 300/5
x = 60
There were 60 small cars washed.
Answer:
60 words per minute
Step-by-step explanation:
"per" means "divided by" in this context. When you want "words per minute", it means you want the number of words divided by the corresponding number of minutes:
... (900 words)/(15 minutes) = 60 words/minute
Here's the solution ~
Now we will use this identity in denominator
[ a² - b² = (a + b)(a - b) ]
