the equation is y=2x-5 change the x for the number of pens
Answer:
10
Step-by-step explanation:
-2*2-3x+5=f(x)
-2*2-3(-3)+5=f(x)
-4+9+5=f(x)
5+5=f(x)
10=f(x)
Answer: Sample space for:
Coin (S) ={H, T}
Spinner (S) = {Green, Red, Orange, Purple, Yellow}
All the Possible outcome for:
Coin =1
Spinner = 1
The total outcome there = 7
Probability of flipping tails and not spinning purple or green
=11/10
Step-by-step explanation:
All the Possible outcome for:
Coin =1/2+1/2=1
Spinner = 1/5+1/5+1/5+1/5+1/5=1
The probability of flipping tails. = 1/2
The probability of not spinning purple or green = 3/5
Therefore, the probability of flipping tails and not spinning purple or green
= 1/2+3/5
=11/10
Answer:
21, 23, 25
Step-by-step explanation:
Ok, so this one may seem a little tricky, so I'll try to explain it as best as I can. :)
So because they are consecutive odd numbers, that means they are odd numbers that are one after the other. This means each number is 2 apart from the next. So by using this, we know that there is a difference of 6 between the highest and lowest number. Now let's try and make an equation:
3o + 6 = 69
Now in order to get O by itself we have to subtract 6 from both sides:
3o = 63
Now we just have to divide by three on both sides:
o = 21
So now, we know that the lowest number is 21, but we have to add 2 to get 23, and then another 2 to get 25.
Hope this helps :)
