Answer is X=3

15x-12+7x+6=60
Explanation:
22x-12+6=60
22x-6=60
22x=60+6
22x=66
Divide both sides by 22
And x=3

Answer:

The answer is 3

Step-by-step explanation:

If you combine like terms you get 22x - 6 = 60

Then you set the numbers and x's apart = 22x = 66

lisabon 2012 [21]

Answer: Margin of Error = 1.944

Lower Bound = 3.052

Explanation:-

Attached below is a file for monthly Rate of return. Used an excel sheet to determine the confidence interval which seems relatively easier as compared to manual computation. The range below (A2:A40) shows the monthly

Functions used : Standard Deviation as= STDEV (A2:A40)

Sample Mean = AVERAGE(A2:A40)

Margin of Error = CONFIDENCE.T(D4,D5,D2)

Lower Bound Interval = D6-D7 = -3.052

Question 1:

5z – 9 = 36

5z = 45

z = $\frac{45}{5}$

z = 9

Hence, the answer is D.

Question 2:

5(2z + 4) = 0

10z + 20 = 0

10z = -20

z = $\frac{-20}{10}$

z = -2

Hence, the answer is A.

Question 3:

4a + 3(a + 1) = 24

4a + 3a + 3 = 24

7a = 21

a = $\frac{21}{7}$

a = 3

Hence, the answer is B.

Question 4:

3(4x + 5) = 12

12x + 15 = 12

12x = 12 - 15

12x = -3

x = $\frac{-3}{12} = - \frac{1}{4}$

Hence, the answer is A.

Question 5:

4x – 8 – 4x = 9

-8 ≠ 9

Hence, the answer is A.

3ln(4x)=13

Kryger [21]

3 * ln 4x = 13

<=> 

ln 4x = 13/3 

<=> 

4x = e^(13/3) 

<=> 

x = e^(13/3) / 4 

<=> 

x ~ 19.05
