Mark owes sally 85.00$ he finds 14 friends to help him pay her back. How much does each friend need to pay? (This includes mark)
<span>If you are given a mean and asked for one of the data values, you can still use the basic method for determining the mean, but work backwards. Generally we add up all the values and then divide by the number of values. In this case, working backwards, we multiply by the number of values (instead of dividing) and then subtract (instead of adding). You should be left with a data value from the set. </span>
Answer:
234500000020000000000000000
Step-by-step explanation:
When you divide exponents, you have to subtract them. So -4-3= -7 as the exponent
When you have a negative exponent, then you have to flip the fraction (all whole numbers are over 1 so flip the 1 to the top and the 5^7 on the bottom)
Answer:
B
Step-by-step explanation:
First, subtract 3 by the numbers
-8 > 4x > 4
Remember to flip the inequality signs
Second, divide all the numbers by 4
-2 < x < 1
Flip the inequality signs again
-2 > x > 1
I am not very experienced with these problems so I might be wrong.
