What you are hoping for is that it is a right triangle. Use Pythagoras formula. c2=a2+b2 where c is the longest side. IF you get a true statement out of this then your triangle is a right triangle. 162=102+112? 256=100+121? 256=221? no, 256 does not equal 221, so in this case it is not a right triangle
.and it is scalene triangle with three different sides

It is a scalene triangle as all the sides are unequal in length.

A chef uses 5 pounds of flour to bake 120 blueberry muffins.

Cloud [144]

Answer:

Step-by-step explanation:

You can solve this problem by setting up a ratio. 5 pounds of flour makes 120 muffins, so the ratio of pounds of flour to muffins is 5:120=1:24. This means that you can make 24 muffins with 1 pound of flour. Multiplying both of these by 2, you get 24*2=48 muffins with two pounds of flour, or answer choice A. Hope this helps!

Kelly needs to order lunch for orders 6 people at a business meeting. Her menu choices are chicken salad for a cost of $5 per pe

nirvana33 [79]

Ok , with that information we can write the equations
x + y = 6
5x + 4y = 28

Where x = how many people ordered chicken
and y = how many people ordered egg salad

Through elimination , we can set one of the variables in both equations equal so we can eliminate it :

(4)x + (4)y = (4)6
5x + 4y = 28

4x + 4y = 24. equation 1
5x + 4y = 28. equation 2

Now we can subtract the second equation by the first equation and isolate one variable:
equation 2 - equation 1

5x - 4x + 4y - 4y = 28 - 24

x = 4

Now that we discovered our x value ( How many people ordered chicken salad ) , we can apply it to one of the equations and discover y ( how many people ordered egg salad)

x + y = 6
x= 4
4 + y = 6

We can shift 4 to the other side of the equation by subtracting 4 from both sides of the equation:
4 - 4 + y = 6 - 4
y = 2

x=4 and y=2

So the awnser is :
4 people ordered chicken salad and 2 people ordered egg salad!

I hope you understood my brief explanation!!
