In order to simplify an expression you have to have the same variables, to the same power.
1a) There are no more H's or numbers without a variable.
1b) The variables do not match.
1c) The variable is to a different power so it can't be simplified.
So to simplify you combine your "like terms"
2a,b, and c are correct :)
2d) already simplified
2e) since the variables are the same, just focus on the numbers (x=h since it won't let me use it) answer: 6x

2g) For this one 9 has no variable and no like terms, so it stays by itself, just focus on the a's (x=a) answer: 9+4x

2j) answer: 11y^2+5y
Answer:
-1/5m+-4/5
Step-by-step explanation:

The location of point Y is the point -3 on the number line
Here, we want to find the location of Y
let us say the point 0 represents the origin
The coordinates of point x will be (-9,0) while the coordinates of point z will be (3,0)
To find the location of Y , we proceed to use the midpoint formula as follows;

Thus, we have;
(-9 + 3)/2 , (0 + 0)/2
= -6/2 , 0
= (-3 , 0)
Answer:
1.2 pounds of chicken per serving.
Step-by-step explanation:
4 and 4/5 of pounds of chicken for serving of 4.
We can also write this as 4.8 pounds of chicken.
To find how much pound of chicken will be needed for a single serving we have to divide 4.8 by 4.
