What is the solution to the equation?2 - Z/3 = 12

Please help me. Thanks~! ^^

A. z = -42

B. z = -34

C. z = 30

D. z = 42

Answers

Answer 1

Answer: The answer is C because you; need to add instead of subtracting to get a positive number.

Answer 2

Answer: 2 - z / 3 = 12

Multiply both sides by 3 :

3 * 2 - 3 * ( z / 3 ) = 3 * 12

Refine :

6 - z = 36

Subtract 6 from both sides:

6 - z - 6 = 36 - 6

- z = 30

Divide both sides by - 1

- z / - 1 = 30 / - 1

z = - 30

answer C

hope this helps!

A rectangle is divided into 8 equal parts.two parts are shaded.what fraction is equivalent to the shaded area of the rectangle

Answers

The total shaded area must be 2/8 = 1/4 of the whole area.

Final answer:

A rectangle divided into 8 parts, with 2 parts shaded, represents the fraction 2/8, which can be simplified to 1/4 or expressed as a decimal, 0.25.

Explanation:

The student's question is related to the concept of fractions in mathematics. In this case, a rectangle is divided into 8 equal parts and the two of these parts are shaded. The fraction that represents the shaded area of the rectangle is therefore 2/8.

However, it's important to note that fractions can be simplified to their lowest terms. Both the numerator (the top number) and the denominator (the bottom number) of the fraction 2/8 can be divided by the common factor of 2. When you do this, you get 1/4.

So, the fraction that is equivalent to the shaded area of the rectangle is 1/4 or 0.25, when expressed as a decimal.

The minute hand of a clock is 7 inches long how far does the point of the hand travel in one hour

Answers

The hand represents the radius of the circle of the clock, so we would want to find the perimeter of the circle to begin with to determine how far the point of the hand would travel full circle (12 hours) To do this we would use the equation 2(pi*radius) we would use 3.14 as pi in this equation.

p=2(3.14*7) solves to 43.98 inches. This means the point of the hand travels 48.98 inches in 12 hours, to find how far it moves in just one hour, we would divide 43.98 by 12. This gives us the final answer of 3.665 inches traveled in one hour.

i am a 3digit number that is less than 500. My ones digit is twice the hundreds digit. The sum of the three digits is 14. What number am I?

Answers

the three possible answers are 428, 356, and 284. All are less than 500, all have a units digit twice the hundreds digit, and all have 14 as a sum of digits.

ooh fun

so xyz=number
z=2x
x+y+z=14
subsitute z=2x into x+y+z=14
x+y+(2x)=14
3x+y=14
number must be 3 digit and less thaan 500
since the tens digit's max is 9 then
z+x≥14-9
z=2x
3x≥5
x max=5 because 500 is max so
x could be 2,3,4 so

284
356
428
are the numbers
