2x -  \frac{7}{3}  = 1 \\  \\ 2x = 1 +  \frac{7}{3}  \\  \\ 2x =  \frac{3 + 7}{3}  \\  \\ 2x =  \frac{10}{3}  \\  \\ x =  \frac{5}{3}  \\  \\ x = 1 +  \frac{2}{3}  \\  \\ x = 1 + 0.66666 \\  \\ x = 1.66666

Simplify the expression: <br> sin^4x cosx/ cos^4x sinx
netineya [11]

Answer:

tan^3x

Step-by-step explanation:

We want to simplify:

\frac{\sin^4x\cos x}{\cos^4x\sin x}

This is the same as:

\frac{\sin^3x \sin x\cos x}{\cos^3x \cos x\sin x}

Cancel out the common factors to get;

\frac{\sin^3x}{\cos^3x}

This is the same as

(\frac{\sin x}{\cos x} )^3=tan^3x

Which of the following is the graph of the solution set of t – 4 ≥ 4t + 8 or 3t &gt;14 – 4t?
Stells [14]

Answer:

Option (C)

Step-by-step explanation:

There are two inequalities,

t - 4 ≥ 4t + 8 ------(1)

3t > 14 - 4t ------(2)

By simplifying inequality (1),

t - 4 ≥ 4t + 8

t ≥ 4t + 8 + 4

t ≥ 4t + 12

t - 4t ≥ 12

-3t ≥ 12

t ≤ \frac{12}{(-3)}

t ≤ -4

By solving inequality (2),

3t > 14 - 4t

3t + 4t > 14

7t > 14

t > \frac{14}{7}

t > 2

From the given graphs, Option (C) will be the answer.

Emma is 9 1/4 years old . how many months is Emma please answer
coldgirl [10]
Well we know there are 12 months in 1 year
So since she lived 9 already lets multiply that
12 x 9 = 108
so far she lived 108 months but wait! we still need to add 1/4 of a year
lets find out how many months 1/4 of a year is by dividing 12 and 4 
sooo heres the math
12 ÷ 4 = 3
so she lived another 3 months.
Lets add on 108 and 3
108 + 3 = 111
so she lived 111 months her entire life
hope this helps 
and dont forget 2

If the average, mode, and range of 5 different numbers are all 8, find the sum of all possible values of the second largest numb
ANTONII [103]

I believe you meant:

If the average, mode, and range of 5 different numbers are all 8, find the sum of all possible values and the second largest number

Answer:

Sum of all possible values = 40

Second largest number= 8

Explanation:

Since our mean, mode, and range is 8, our sum is 40 and our second largest number is 8.

The sum of all the numbers is 40 since our mean is 8 and there are 5 numbers(8×5)

To find possible values, we already know the mode is 8 and so we know 8 must appear more than once. If we have 8 twice then we are left with 24(sum is 40). We have 3 numbers left and the range is 8 so we must have a maximum number and minimum number that has a difference of 8 and a third number, all adding up to 24(sum left). Within 24, only 12-4+8 satisfies the condition, hence our numbers are: 4,8,8,8,12.
