Answer:
Jake is 9, and Jake's dad is 43.
Step-by-step explanation:
Ok, let's start off by putting a variable for Jack's age, A.
We know that Jack's father is 2 less than 5 times, so we can write his as 5x -2.
Now let's make an equation:
52 = x + 5x - 2
We need to isolate the x-values so we need to add 2 on both sides:
54= x + 5x
No we need to add the like terms:
54 = 6x
Finally, we just divide by 6 on each side.
Now we know X = 9 but we're not done yet :)
So because Jake's dad is almost 5 times as much, we first multiply Jack's age by 5. We get 45 but we need to subtract 2 which leaves us with 43.
Answer:
To provide a situation of 1 and O, here is a situation
Step-by-step explanation:
The acceleration would be 1.
If the acceleration is 10 m/s, the object will gain more speed.
On the other hand, if the acceleration is -10m/s, then the object will lose speed.
In the case of 1, the object gained more speed, in the case of 0, the object will lose speed.
So we want to see which number line shows the sum 1.5 + 2.5. We will see that the correct option is <u>"An arrow goes from 0 to 1. 5 and from 1. 5 to 4"</u>
So the number line usually starts at 0 and goes to the first number, 1.5 in this case.
Then, it moves accordingly to the second number, 2.5 (so it will move 2.5 units to the right)
So the number line should start at 0 and move to the right until it meets 1.5 + 2.5 = 4.
From the options, the only that is correct is:
<u><em>"An arrow goes from 0 to 1. 5 and from 1. 5 to 4"</em></u>

The correct answer is b), the probability of B occurring given A has occurred.
