(m 5/6) (m1/6) ^7 = m^x

nadezda [96]

Answer:

x = 2

Step-by-step explanation:

Here, we want to find the value of x

(m^5/6)(m^1/6)^7 = m^x

= (m^5/6)(m^7/6) = m^x

Using the law of indices for power multiplication

m^(5/6 + 7/6) = m^x

m^(12/6) = m^x

m^2 = m^x

we simply equate the powers in this case since the base are equal

Thus we have

x = 2

What is the measure of NRS?

never [62]

Answer:

Step-by-step explanation:

(7x - 1) + 79° = 21x + 8

• An exterior angle of a triangle is equal to the sum of its two interior opposite angles.

$(7x - 1) +79 = 21x + 8 \\ 7x - 1 + 79 = 21x + 8 \\ 7x + 78 = 21x + 8 \\ 78 - 8 = 21x - 7x \\ 70 = 14x \\ \frac{70}{14} = x \\ 5 = x \\$

NRS = 21x + 8

$21x + 8 \\ 21(5) + 8 \\ 105 + 8 \\ {113}^{o}$

The product of 5 and a number X is 1/4

Sloan [31]

Hi!

5x = 1/4

5x = 0.25

<h3>Divide by 5 on both sides</h3>

5x/5 = 0.25/5

x = 0.05

<h3>Convert 0.05 to a fraction</h3>

5/100

<h3>Simplify the fraction</h3>

1/20

<h2>The answer is X=1/20</h2>

Hope this helps! :)

Jessica made 124 cookies. She put the cookies into three boxes, A, B and C.

Oxana [17]

There are 78 cookies in box C, 26 cookies in box B and 10 cookies in box A.

let the number of cookies in first box be represented mathematically as B-16

the number of cookies in second box be represented as B

the number of cookies in third box be represented as 3B

Since there are 124 cookies we can make an equation such that it becomes

B-16 +B +3B =124

Solving for B, we have

5B -16 =124

5B =124 +16

5B =130

B=130/5

B=26

Therefore Box A contains B-16 =26-16 =10 cookies

Box C contains 3B =3 X 26=78 cookies
