Answer:
x=3 and y=
4 / 3 (Fraction)
Step-by-step explanation:
Substitute x for 6y-5.
2(6y−5)−3y=2
Add 6y and 3y, and multiply 5 by 2/Simplify the equation.
9y−10=2
Add 10 to both sides, and then divide each side by 9.
9y−10+10=2+10
9y / 9 = 12 / 9
y = 4/3.
Repeat the process but replace y with 4/3!
Answer:
Choice C
Step-by-step explanation:
Bryan owes MORE than $1930 which means how much he pays back is going to be greater than 1930$
And so, $200 + $173 for certain number of months is going to be more than 1930.
Therefore, $200+ $173x >$1930
Hope this helped..
Have a great day : )
Answer:
There are six boys
Step-by-step explanation:
Divide 54 sheets by number of boys (9)
Given that the scale readings of the laboratory scale is normally distributed with an unknown mean and a standard deviation of 0.0002 grams.
Part A:
If the weight is weighted 5 times and the mean weight is 10.0023 grams, the 98% confidence interval for μ, the true mean of the scale readings is given by:

Thus, we are 98% confidence that the true mean of the scale readings is between 10.0021 and 10.0025.
Part B:
To get a margin of error of +/- 0.0001 with a 98% confidence, then

Therefore, the number of <span>measurements that must be averaged to get a margin of error of ±0.0001 with 98% confidence is 22.</span>
A) 81 and 48 have a common factor of 3:
81w+48= 3(27w+16)
b) 10 and 25 have a common factor of 5:
10-25t=5(2-5t)
c) 12, 16 and 8 have common factors of 4:
12a+16b+8=4(3a+4b+2)
Hope this helps :)
