It would be number 3 hope this helps!
Answer:
x = 5
Step-by-step explanation:
20(20-x)=300
1. Divide both sides by 20.
20(20-x)/20 = 300/20
2. Simplify.
20-x=15
3. Subtract 20 from both sides.
20-x-29=15-20
4. Simplify.
-x=-5
5. Divide both sides by -1.
-x/-1 = -5/-1
6. Simplify.
x=5
Answer:
B
Step-by-step explanation:
There are 6 values on the faces of a standard number cube, that is
1, 2, 3, 4, 5, 6
There are 4 values > 2, that is 3, 4, 5, 6
P( number > 2 ) = 
= 
→ B
Answer:
Well, there are 60 min. in one hour, so 10*6=60. Then we have to multiply 3 by 10 as well. So the answer is D: 30 busses.
For this case we have the following function:
F (x) = (5x-2) / (x ^ 2 + 3)
Let's evaluate the function for x = 2
We have then:
F (2) = (5 (2) -2) / ((2) ^ 2 + 3)
F (2) = (10-2) / (4 + 3)
F (2) = (8) / (7)
Then we have:
(3/2) * F (2)
Substituting:
(3/2) * (8/7)
Rewriting:
(3/2) * (8/7) = 24/14
Simplifying:
24/14 = 12/7
Answer:
12/7
