Answer:
A 2-column table with 3 rows titled Marissa's Hair Growth. Column 1 is labeled Months with entries 4, 6, 8. Column 2 is labeled Growth (inches) with entries 3, 4.5, 6.
Step-by-step explanation:
One of the given points on the graph is (4, 3), which corresponds to a table entry of Months = 4, Growth = 3.
Two tables have entries like that.
__
The points on the graph have a difference of 2 months, and a corresponding difference in growth of 1.5 inches. Only one of the two tables has entries like that. See below.
Before it charged, the battery was at 23%. In half and hour, it went to 89%. So, it rose 89-23, or 66% in half an hour. Now that we know how much it rose and that there are 30 mins in half an hour, we have to divide 66% by 30 to figure out the answer.
66/30 is 2.2.
So, the battery rose at 2.2% per minute.
Hope this helps!

Answer:
170
Step-by-step explanation:
Answer:
The number is 48
Step-by-step explanation:
First, let's call the number we are looking for n.
We can then write "two-thirds of the number" as 2/3n
We can also write "one-half of a number" as 1/2n
Finally, we are told 1/2n is the same as 2/3n −8 or: 1/2n = 23n −8
We can now solve for n: 1/2n − 2/3n = 2/3n −8 − 2/3n 1/2n − 2/3n = −8We next need to get the fractions over common denominators, in this case, 6 by multiplying each fraction by the necessary for of 1: (3/3) 1/2n − (2/2) 2/3n = −8 3/6n − 4/6n = −8 − 1/6n = −8.
We can finally solve for n by multiplying by -6 to isolate n −6 ⋅(−1/6)n = −8⋅ − 6
1n = 48
n =48
