I think it’s 15 u put the two equations equal to each other
they are Vertically Opposite Angles..
u multiply each number with the number diagonal to it!
the area is half of the products of the numbers which were multiplied to the numbers SE to them minus the products of numbers which were multiplied to numbers southwest to them
20 fish, 8 multiplied my 2.5 because 25 is 2.5 times greater than 10.
Set up a proportion. 3.50 over 5 = x over 1 (x is what we are trying to find= the cost of 1 lb of apples)
Use cross products and multiply 3.50 by 1 to get 3.50 and then divide that by 5 to get 0.7.
So the apple cost 0.7 or seventy cents per pound.
Check: 0.7*5=3.5
That is correct!
Hope this helps!
Can u plz mark me as brainliest? I really need it!
