4.
The equation we have is:

To solve for "a", we want to isolate it in one side.
For this. we can start by multiplying each side by 5. This will make the denominator to cancel out:

Now, we can divide both sides by 8, which will cancel the coefficient 8 multiplying "a":

And that is the answer to 4.
X + (x + 1) + (x + 2) + (x + 3) = -26
Even though it says negative, the same rules apply.
4x + 6 = -26
4x = -32
x = -8
-8, -7, -6, -5
Hope this helps!
Answer:
4 would be rolled 60 times when the dice was thrown 3000 times.
Step-by-step explanation:
3000/50 is how many times 4 would be rolled
Answer:
n=-3.1
Step-by-step explanation:
To solve this, first subtract 3 from both sides of the equation to get 2n=-6.2. Next, divide both sides of the equation by 2 n order to get the final answer of n=-3.1
So electricity costs 15cents every 1,000 watts used, and if he watches tv for 2hrs every day for a month that’s 60 hours (2*30) And every hour he watches tv it’s 150 watts. They want you to do the 60 hrs times 150watts which is 9,000 (amount of watts he uses in the month) and remember 1,000 watts is 15cents
