Answer:

The Correct answer is option D

Step-by-step explanation:

In order to pick an answer, you have to solve each of the statements from the option.

We know that 4 divided by 1/8 is 4 x 8 = 32. Any of these statements have to equal 32.

Option A would be 4 x 1/8 = 4/8 = 1/2. A is not the answer.

Option B would be 4 + 1/8 = 4 1/8. B is not the answer.

Option C would be 4 - 1/8 = 3 7/8. C is not the answer.

Option D would be 4 divided by 1/8 = 32. You have 4 yards of fabric and you cut each into 8 pieces. You basically have 4 pieces of fabric divided into 8 pieces, count them all, and you have 32.

Thus, the answer is D. Option D gives 32.

Find the output, k, when the input, t, is -7−7minus, 7.<br> k = 10t-19k=10t−19
sleet_krkn [62]

The value of k is -89

Explanation:

The given expression is k=10t-19

We need to determine the output k, when the input t is -7

<u>Output k:</u>

The value of the output k can be determined by substituting the input t=-7 in the expression k=10t-19

Thus, we have,

k=10(-7)-19

Multiplying the terms 10 and -7, we have,

k=-70-19

Simplifying, we get,

k=-89

Thus, the value of k is -89

Solve (6-5x)/10-(2x+1)/5+x/3=2x/15
Ulleksa [173]
Multiply2 * x/15 to 2x/15

multiply both sides by 30 which is the LCM of 10, 5, 3, and 15

expand it

simplify 18 - 15x - 12x - 6 + 10x to 12 - 17x

add 17x to both sides

add 4x + 17x to = 21x

divide both sides by 21

simplify 12/21 to 4/7

now simplify

Answer: x = 4/7.

Marina CMI [18]

Answer:

old per: 1280

Step-by-step explanation:

first perimeter u get it by adding all the sides and since its a square  then all the sides are equal so u can just do

320*4 which is equal to 1280

and by doubling the sides u can just double it in the old equation meaning

(320*2)*4
