How many solutions does the equation have?a+5=1/5(15+5a)

A. one solution B. infinite solutions C. no solution

Answers

Answer 1

Answer: The first thing we need to do is distribute on the right side. 1/5 * 15 is 3, and 1/5* 5a is 1a, so now the equation is a+5 = 3+a
Subract 3 from each side and you have a+2=a
There are no solutions because any number +2 will never equal itself. This is incorrect, because the two sides are not equal to each other, so there are no solutions(:
I hope that helped(:

in a first aid kit the ratio of large bandages to small bandages is 5 to 2. Based on this ratio, how many large bandages are in the kit if there are total of 60 bandages?

Answers

The best way to answer this question is to set up the first sentence as a ratio of large bandages to total bandages. You would write 5 large bandages to 7 total bandages to 7 total bandages. Then you would make this equivalent to x number of large bandages to 60 total. It would look like this 5:7 = x:60. You could use cross products to multiply 60 by 5 to get 300. 7 times x also should equal 300. Unfortunately, this example will not leave us with a whole number of bandages, but 300/7 is a repeating decimal or a mixed number (42 6/7 large bandages).
