Answer:
20
Step-by-step explanation:
If you split up 8 you get 4 which means that each week you have 4quizzes. So 5 • 4 = 20
<span>equation 1/5x-2/3 y = 30, when y = 15?
so
</span><span> 1/5x-2/3 (15) = 30
1/5x - 10 = 30
1/5x = 40
x = 40(5)
x = 200
answer

second one is right

Answer:
Since the exponent on 10 is positive, I know they are looking for a LARGE number, so I'll need to move the decimal point to the right, in order to make the number LARGER. Since the exponent on 10 is "12", I'll need to move the decimal point twelve places over.
First, I'll move the decimal point twelve places over. I make little loops when I count off the places, to keep track:
3.6 _ _ _ _ _ _ _ _ _ _ _ .
Then I fill in the loops with zeroes:
3.600000000000.
In other words, the number is 3,600,000,000,000, or 3.6 trillion
Step-by-step explanation:
Answer: t=-5
Step-by-step explanation:
if 10t=-50, you have to solve for the equation. to solve, you have to get the variable by itself. to get the variable by itself, you have to divide both sides by 10. 10t/10=-50/10. t=-5
