Answer:
She has 16 friends
Step-by-step explanation:
40 minus 8 is 32 so that divided by 2 is 16
Answer:
A. 3x + 12
B. US$ 34.50
Correct question and statement: Three friends went to lunch. They all ordered the same meal. At the end of lunch they gave the waiter a $12 tip.
A. Write a algebraic expression to represent the situation.
B. How much total money was spent if each meal cost $7.50?
Source: Previous question found at brainly
Step-by-step explanation:
A. If the three friends ordered the same meal, we have then:
x = Cost of the meal
Tip = US$ 12
<u>3x + 12 </u>
Total of the meal would be three times the cost of the individual meal, x, plus the tip.
B. Given that x = 7.50, how much was the total cost?
Let's use the equation we wrote in part A.
3x + 12
3 (7.50) + 12
<u>22.50 + 12 = 34.50</u>
Answer:
s = 3
Step-by-step explanation:
First compute the cost of the three apps:
21-12=9
The cost of the three apps is $9 then.
Since s is the price of the apps, we deduce the equation:
3s=9
/3
s = 3
Answer:
21
Step-by-step explanation:
Start with the inside first.
The inside is g(3).
g(3) can be found by using function, g.
g(x)=3x-4 so g(3)=3(3)-4=9-4=5.
So now we have that:
f(g(3))
f(5)
We can find f(5) by replacing x in the expression x^2-2x+6 with 5:
(5)^2-2(5)+6
25-10+6
15+6
21
This means f(g(3))=f(5)=21
