Answer:
-0.4-4y
Step-by-step explanation:
-0.5(0.8+8y)
Distribute -0.5 into the parentheses
= -0.5×0.8+(-0.5)×8y
= -0.4+(-4y)
A negative and a positive make a negative
= -0.4-4y

Answer:
The answer is the last one.
Step-by-step explanation:
Firstly, look at the first inequality and we get [tex]4x+5<13[/tex], so [tex]x<2[/tex]. In the second inequality, we have [tex]15\leq 2x[/tex], so [tex]x\ge 7.5[/tex]. Together, we know that the answer is the last one.

What is the probability of spinning a odd number, flipping heads, then spinning a 3?
Answer:
Probability of spinning a odd number is 5/9
I don't know about flipping head
Probability of spinning a 3 is 1/9
=========================================================
Explanation:
The sample space of the spinner is {1,2,3,4,5,6,7,8,9} which represents all the possible outcomes. We can only pick one of those values. Of that list, the subset {1,3,5,7,9} represents all the odd numbers. This is the event space because we want to land on an odd number.
There are 5 items in the event space and 9 items in the sample space. The probability of getting an odd number is 5/9.
The probability of flipping heads is 1/2 since we have one side we want (heads) out of two sides total.
Lastly, the probability of landing on a '3' is 1/9 because there's only one '3' out of 9 values total.
---------
We'll multiply those fractions to get the final answer. This works because each event is independent of one another.
(5/9)*(1/2)*(1/9) = (5*1*1)/(9*2*9) = 5/162
Now use your calculator to find that: 5/162 = 0.030864 approximately which rounds to 0.0 or just 0 when rounding to the nearest tenth.
Unfortunately this is one case where rounding will creates a misleading result. The true probability isn't 0 because the events described are possible. The probability is just really small.

Point C is the midpoint of ⎯⎯⎯⎯⎯⎯⎯⎯ A B ¯ , point D is the midpoint of ⎯⎯⎯⎯⎯⎯⎯⎯ A C ¯ , point E is the midpoint of ⎯⎯⎯⎯⎯⎯⎯⎯⎯ A D ¯ , and point F is the midpoint of ⎯⎯⎯⎯⎯⎯⎯⎯⎯ A E ¯ . If =3 A F = 3 , what is the number of units in the length of ⎯⎯⎯⎯⎯⎯⎯⎯ A B ¯ ?
The number of units in the length of AB is 56 units by using the concept of midpoint and the whole length is twice the length of half.
3x-38=28 solve for X
Answer:
Answer:22
Step-by-step explanation:
Answer:
x=22
Step-by-step explanation:
add 38 to both sides
you'll have 3x=66 after adding
then divide both sides by three so have x by itself and you'll get
x=22

The ratio of dogs to cats in a pet store is 4 : 34:3 . The ratio of cats to fish in the same pet store is 2 : 92:9. If there are 24 dogs in the pet store, how many fish are there?
Answer: In the pet store, there are 81 fish.
Step-by-step explanation:
We know that:
The ratio of dogs to cats is 4:3
(this means that for every 4 dogs, there are 3 cats)
The ratio of cats to fish is 2:9
(this means that for every 2 cats, there are 9 fish).
Now, we know that there are a total of 24 dogs in the pet store.
Remembering that for each 4 dogs we have 3 cats, we first need to see how many times we have 4 dogs in a total of 24 dogs, this is:
24/4 = 6
So we have 6 times 4 dogs, then we will have 6 times 3 cats, this is a total of:
6*3 cats = 18 cats.
And now we know that for every 2 cats we have 9 fish.
Then we need to see how many times we have 2 cats in a total of 18 cats, this is:
18/2 = 9.
And for each one of these 9 groups, we will have 9 fish, then the total number of fish is:
9*9 = 81 fish
In the pet store, there are 81 fish.
Solve for a.
5a - 2 = 23
Answer:
5a - 2 = 23
Add 2 to both sides
5a -2 + 2 = 23 + 2
Add 23 + 2 you will get 255a = 25
Divide both sides by 55a/5 = 25/5
a = 5 as the answer
