Answer:
x = - 3, y = - 1
Step-by-step explanation:
y = 7x + 20 -----> equation 1
4x - y = - 11
4x - ( 7x + 20 ) = - 11
4x - 7x - 20 = - 11
- 3x = - 11 + 20
- 3x = 9
x = 9 / - 3
x = - 3
Substitute x = - 3 in equation 1,
y = 7 ( - 3 ) + 20
= - 21 + 20
y = - 1
Hence,
x = - 3
y = - 1
Well, due to that 10% of the muffins get wasted and do not sell,
plus work that goes into it, the price of the ice-cream is not 0.60,
but 55% more, or markup above that cost value
so... how much would each muffin sell for? well, each muffin will be,
0.60 + 55% of 0.60
how much is 55% of 0.60?

get the 55%, and add it to the 0.60, that's how much each will sell for
18,430! I hope this helps you out!

Answer:
Rounded to the nearest tenth, the length of the missing side is 5.4 in.
Step-by-step explanation:
According to the Pythagorean theorem,
, where c is the length of the hypotenuse (the longest side), a and b are the lengths of the other two sides. We can use this to solve for the length of the hypotenuse of the right triangle shown in your question (the missing side):

This simplifies to
. Now to solve for c (the length of the hypotenuse), we just take the square root of both sides of the equation and solve like so:

This simplifies to c≈5.4 in.
