It should be around 24.56 i rounded tho
Step-by-step explanation:
You should prolly subtract 2 from both sides first.
So you get, -|2/5x + 3| > -1 2/5
- Add three to both sides
- -|2/5x| = -1 2/5
- Do -1 and 2/5 divided by 2/5 to get -3.5, x > -3.5
One of the answers is x > -3.5 but you need to switch the sign to less than and make the other side the opposite.
You see that, switched the sign and made whats on the right side opposite. So now solve for x again but with this new equation. Also, the parentheses are absolute value signs
Subtract 3 from both sides
-|2/5x| < -1 and 3/5
Divide 2/5 from each side to get x < -4
I hope I'm correct, my bad if I'm wrong
Answer:
3 seconds
Step-by-step explanation:
You want to set h(t)=3, then take the root such that t≠0. You would have:
3=3+48t−16t^2
Let's solve your equation step-by-step.
3=3+48t−16t2
Step 1: Simplify both sides of the equation.
3=−16t2+48t+3
Step 2: Subtract -16t^2+48t+3 from both sides.
3−(−16t2+48t+3)=−16t2+48t+3−(−16t2+48t+3)
16t2−48t=0
Step 3: Factor left side of equation.
16t(t−3)=0
Step 4: Set factors equal to 0.
16t=0 or t−3=0
t=0 or t=3
3 makes more sense than 0 because the ball can't have been in the air for 0 seconds.
So the ball was in the air for 3 seconds.
This is true. The numbers being arranged differently in this does not mean it'll not equal each other.
Answer:
<u>7 groups of 8 = 6 groups of 8 plus 1 group of 8</u>
Step-by-step explanation:
1. Let's review the information given to answer the question correctly:
7 groups of 8 = 6 groups of 8 plus ?
2. Let's answer the question, this way:
How much are 7 groups of 8? 56 = 7 * 8
How much are 6 groups of 8? 48 = 6 * 8
What is the difference between 7 groups of 8 and 6 groups of 8?
(7 - 6 ) * 8 = 1 * 8
Therefore,
<u>7 groups of 8 = 6 groups of 8 plus 1 group of 8</u>
