The answer is the second option.
To find the answer quickly, fist look at the signs associated with the terms. The is a negative sign with the B and C in the original equation, and the second option is the only one that follows that.
You use 6 as the C since that is a shared value when multiplying 2 and 3, so 1/2 becomes 2 and 1/3 becomes 3.
Option 3 is the correct one
Answer:
x = 6
Step-by-step explanation:
3x + 5 = 5x - 7
Combine like terms:
3x - 5x + 5 = -7
-2x + 5 = -7
Subtract 5 on both sides
-2x + 5 - 5 = -7 - 5
-2x = -12
x = 6
Hope this helps!! :)
Answer:
Definetly B
Step-by-step explanation:
It show that you have to subtract both with y and x.
Answer:
B. 61%
Step-by-step explanation:
When we have the standard deviation of a sample, we use the t-distribution.
The width of an interval is related to the margin of error, which is given by the following equation:
M = T*s
In which T is related to the confidence level(and the sample size) and s is the standard deviation of the sample. Higher confidence levels have higher values of T.
A higher margin of error means that the interval is wider. To have a higher margin of error, we desire a higher value of T, which is achieved with a higher confidence level.
So the correct answer is:
B. 61%
