Answer & Step-by-step explanation:

If you simplify the given equation of y=kx to solve for k, you would divide both sides by x:

y=kx\\\\\frac{y}{x} =\frac{kx}{x}\\\\\frac{y}{x}=k

We are told that the constant, <em>k</em>, is 5. So, this can be written as:

5=\frac{y}{x}

a pitcher of fruit punch holds 2 gallons if 9 people share the entire pitcher equally how much punch does each person get
katrin2010 [14]
2×9= 18

18÷9= 2

Answer: 2 cups of fruit punch.

----------

Explanation: so, you divide. why do I know this? because it doesn't say "times," (multiplication word) "more than," (addition word) "less than/ left over." (subtraction word) so what your looking for is "equally," and "each."

So, can you do 2÷9? no, you cant. so you have to multiply 2×9 to get the answer. and what's the answer? 18!

so, now, can you divide 18÷9? yes!! why? because you can only divide big numbers like 18. and you can't divide small numbers like 2 or 9. do you get what I'm saying?

so, what's 18÷9? 2!!


I hope this helps! :) if you still don't understand it just please let me know :)

Answer:

Step-by-step explanation:

Things to remember:

1). When we divide a number having decimal by 10, 100, 1000 or any number multiple of ten, decimal point of the numerator shifts left by the number of zeros present in denominator.

Example:    \frac{2.0}{100}=0.02

2). When we multiply a decimal number by 10, 100, or any number number multiple of 10, decimal point of the original number shifts right by number of zeros present in multiplier.

Example:   2.0 × 100 = 200

In this question, 0.014 × 100000 = 1400.000

Therefore, product of 0.014 and 100000 is 1400 because the decimal point in 0.014 moves 5 places to the right.

If 3x − (7 − x) = 29, find the value of 6x.
Stells [14]

Answer:

54

Step-by-step explanation:

3x -(7-x) = 29       remove the parens

3x - 7 + x = 29     simplify

4x -7 = 29            add 7 to both sides of the equation

4x = 36            divide by

x = 9

then 6x = 6 * 9 = 54
