B. Barbara's equation did not consider the number of bottles of iced tea. She only put 1.49, which would mean she only sold one. Because we know she sells more then one, it should be 1.49(then a variable)
Answer:
The solution of y² - 1 = 15 is +4 and -4
Step-by-step explanation:
Given
y² - 1 = 15
Our solution goes thus;
Make y² the subject of formula
y² = 15 + 1
Add 15 to 1
y² = 16
Take square roots of both sides
√y² = √16
y = √16
Note that the square root of 16 is either +4 or -4 because +4 * +4 = 16 and -4 * -4 = 16; So, we replace √16 with ±4 which means + or -4
y = ±4
y = +4 and -4
Hence, the solution of y² - 1 = 15 is +4 and -4
Answer:
9 to 7 = 45 to 35..
Step-by-step explanation:
Given function:
<u><em>to find x:</em></u>
- divide 45 by 9
- if 9·5=45 then x would be 7·5..
·
Therefore, x=35.
