A. x=the cost of one lunch. 60.25=5x+3(x-5.25)
b. 60.25=5x+3x-15.75 60.25+15.75=8x-15.75+15.75
76=8x 76/8=8x/8 9.50=x
A lunch is $9.50. If you are not sure, check my answers. Hope this helped.
Answer:
50.27 or 16pi
Step-by-step explanation:
Just multiply the diameter by pi
3x + 7 > 4x + 3
subtract 3x from both sides
7 > x + 3
7 - 3 > x
x < 4
A is the answer for this one
Answer:
+
+
+ 2
Step-by-step explanation:
f(x) =
- 4x + 2
g(x) =
+ 2
To find fg(x) , we have
fg(x) = f(
+ 2 )
The next thing is that , we will substitute
+ 2 for the value of x in f(x) , so we have:
- 4(
+ 2) + 2
which will give
+
+
+ 2
Therefore :
fg(x) =
+
+
+ 2
