Answer:
The answer is
<h2>x > 2</h2>
Step-by-step explanation:
- 2x + 4 > - 4x + 8
<u>Add 4x to both sides of the inequality</u>
That's
- 2x + 4x + 4 > - 4x + 4x + 8
2x + 4 > 8
<u>Subtract 4 from both sides</u>
That's
2x + 4 - 4 > 8 - 4
2x > 4
<u>Divide both sides by 2</u>
That's
We have the final answer as
<h3>x > 2</h3>
Hope this helps you
So first you need 1 adult with every 6 children so do 6*4 and got 24. From that you get 4 adults with 2 leftover children. For the other class which has 28 children, you would still need 4 adults. Now since you said the teacher is included as an adult only 3 more are needed for the trip, and that is your answer.
Answer:
x = 2
Step-by-step explanation:
= ( cross- multiply )
5(x + 1) = 3(x + 3) ← distribute parenthesis on both sides
5x + 5 = 3x + 9 ( subtract 3x from both sides )
2x + 5 = 9 ( subtract 5 from both sides )
2x = 4 ( divide both sides by 2 )
x = 2
0.6 = 6/10
0.7 = 7/10
7/9 = 0.77777
0.7 is between the two fractions.
If you need the fraction directly in the middle of the two it is
31/45.
100 = x^2 + y^2
So
2 x dx/dt + 2y dy/dt =0
So
dy/dt = -x/y dx/dt
= -x/sqrt(100-x^2) * 7 At x=3
