Angelo bought apples and bananas at the fruit stand. he bought 20 pieces of fruits and spent $11.50. apples cost $0.50 and bananas cost $0.75. write a system and solve algebraically to determine how many apples and bananas angelo bought.

So for this system, one equation will represent the number of fruit and the other equation will represent the combined total of the fruit. (Let x = apples and y = bananas):

Next, I will be using the substitution method to remove one of the variables. To do this, firstly subtract both sides by y in the first equation:

Next, since we know that x is equal to 20 - y, substitute it into the second equation and solve for y:

Now that we have the value of y, substitute it into either equation to solve for x:

In short, Angelo bough 14 apples and 6 bananas.

the figures below are made out of circles, semicircles, quarter … find the area and the perimeter of each figure and give your answers as a completely simplified exact value in terms of π (no approximations). remember that we'll also have to cut whatever areas we get in half, since we're only dealing im pretty sure that is the right answer

i think it would be 42cm
