Step-by-step explanation: 85 is 56.67 percent of 150
56.67 percent of 2,400 is 1360 so 1360 people gave the play at least 4 stars
To solve for X you must get x by itself so let's get started
-4x+13=6x-7
subtract 13 from both sides
-4x=6x-20
subtract 6x from both sides
-10x=-20
divide both sides by -10
x=2
to check if this is correct plug in x into original equation
-4 (2)+13=6 (2)-7
-8+13=12-7
5=5
answer x=2 holds true :)
Lets just solve it all:
3-6+12-24+48-96
I got 48 and 96 because the change is *(-2)
Now just simplify:
-63
Your answer is -63.
Answer:
See below.
Step-by-step explanation:
So we have the two functions:
And we want to find:
1)
Recall that:
is the same as:
Thus, we can substitute g(x):
And substitute that into f(x):
Distribute:
Subtract and simplify:
Thus:
2)
Similarly:
Substitute f(x):
Substitute:
Distribute:
Simplify:
Therefore:
