Step-by-step explanation:
11+22+54+14=112
$220+$256= 476
476÷112=$4.25
Answer:
- Powers of the variable descending left to right
- right side of the equal sign is 0
Step-by-step explanation:
For some constants a, b, and c, the standard form* is ...
ax^2 + bx + c = 0
___
It is nice if the leading coefficient (a) is positive, but that is not required.
The main ideas are that ...
- Powers of the variable are descending
- All of the non-zero terms are on the left side of the equal sign
- Like terms are combined
_____
* This is the <em>standard form</em> for a quadratic. For other kinds of equations, when the expression is equal to zero, this would be called "general form."
Answer: The answer would be j=19
3x+40=100
subtract 40 from both sides
3x= 60
divide by 3
x=20
each Sweater cost 20
