Answer:

Step-by-step explanation:
The given expression is: 
We multiply by the reciprocal of the second fraction:

We cancel out the common factors to get;
, where
and 
We simplify to get:

Answer:
Part A-19 hamburgers
Part B- 38 sliders
Step-by-step explanation:
Since quarter pound of meat is 0.25, divide 4.75/0.25 to get 19 hamburgers.
Since a slider needs half as much meat as a hamburger, it needs 0.125 pounds of meat. So, divide 4.75/0.125 to get 38 sliders.
Answer:
No they are not
Step-by-step explanation:
in the second expression
it would turn out to be
4^xy+3^xy
Which is way different then just
4+3^xy

Step-by-step explanation.
A system of equations is basically two or more equations that rely on each other. If a solution for a variable is 2, it has to work for the other equation.
The substitution is basically plugging in the y value to y = 8x + 10
If y = 2
and also y = 8x + 10
What do you think the substitution is?
