Answer:

k=23/2=11.5

Step-by-step explanation:

So we have the equation:

6k-8=4k+15

Add 8 to both sides. The left side cancels:

6k=4k+23

Subtract 4k from both sides. The right side cancels:

2k=23

Divide both sides by 2:

k=23/2=11.5

And we're done!

Hi,

Answer:

k = \frac{23}{2}

Step-by-step explanation:

Subtract 4k from both sides

6k - 4k = 2k

2k - 8 = 15

Add 8 on both sides (you want to get rid of the 8 in order to leave the k alone)

2k = 23

k = 23/2

Have a good day!

Hey There!

Here is your answer:

First write the equation down:

-3 4/5 ÷ -3 1/6

Then put the mixed fractions into whole numbers:

-3 4/5= 5×-3=-15+4=-11= -11/5
&
-3 1/6= 6×-3=-18+1=-17= -17/6

Now right the new problem:

-11/5×6/-17

Now multiply:

-11×6=-66
5×-17=-85

Which means -66/-85 is your answer!

Hope this helps!

-8 \cdot f(0) + 4 \cdot g(-8) =−8⋅f(0)+4⋅g(−8)=
kogti [31]

Answer:

-8f(0) +4g(-8)=-32

Step-by-step explanation:

Given

See attachment

Required

-8f(0) +4g(-8)

From the attachment;

f(0) = 1

and

g(-8) = -6

Substitute these values in -8f(0) +4g(-8)

-8 * 1 + 4 * -6

-8 -24

-32

Hence:

-8f(0) +4g(-8)=-32

Sav [38]

Answer:

1. \frac{7^8}{7^6}=49

2. 7

3. 18

Step-by-step explanation:

Question 1:

Given:

The expression to simplify is \frac{7^8}{7^6}.

We use the property of exponent \frac{a^m}{a^n}=a^{m-n}

Therefore, \frac{7^8}{7^6}=7^{8-6}=7^2=7\times 7 = 49

Question 2:

Given:

The expression to simplify is 7(\frac{1}{2}+\frac{1}{2}).

We add the fractions first inside the parenthesis.

So, \frac{1}{2}+\frac{1}{2}=\frac{1+1}{2}=\frac{2}{2}=1

Now, 7(1)=7

Question 3:

The first five prime numbers are 1, 2, 3, 5, and 7.

Therefore, the sum of these five numbers is given as:

1+2+3+5+7=18
