Hi! :)
The answer is A, here's why:
When tipping at a restaurant, first you need to figure out how much you're tipping. You need to move the decimal left 2 places on how much you tip. So for 20%, you get .20
Then to figure out how much to tip for 20%, you would multiply that .20 by how much the bill was and that's your tip. So .20*30=6. Your tip should be 6 dollars, and the formula for that is t=.20<em>b</em>
F(x)=5x+10
5x=-10
x=-10/5
x=-2
Result is f(-2).
It's 248 ft because it increased by 24%, you do 200 ft times 1.24 to get 248 ft.
Answer:
b=1
Step-by-step explanation:
-11+3(b+5)=7
-11+3b+15=7
-11+15+3b=7
4+3b=7
3b=7-4
3b=3
3b/3=3/3
b=1
hope it's helpful
The plus sign means that we have to sum all the terms inside of the second parenthesis, while the minus sign means that we have to change all the signs inside the last parenthesis:
Now we only have to gather all like terms:
