Answer:

7/165

Step-by-step explanation:

We take number after the decimal point 042

then we subtract the non repeating.In this case is 0 so we not subtract anything

This will be the numerator 42

For each repeating decimal we write a 9 (in this case 2 nines)

For each non repeating decimal we write a zero

Denominator is 990

42/990 = 7/165

7:165 = 0.0424242

I think this is what you do. Hope it helps!

What is the steps of 6(6+y)=3(3-y)

deff fn [24]

First you expand the brackets, so
36 + 6y = 9 - 3y
Then you get all the y's on one side
+ 3y
36 + 9y = 9
- 36
9y = 9
Then you divide by 9 to get y by itself
y = 1

The store bought the bike at a wholesale price. The bike store marked up the wholesale cost of the bike by 60%. What was the who

marin [14]

Answer: The wholesale cost of the bike = $100

Step-by-step explanation:

Let x = wholesale cost of the bike

As per given,

Selling price = cost price + (Mark up percent) x ( cost price) (i)

Selling price of bike = $160

Mark up percent = 60% =0.60

Substitute values in (i) , we get

$160= x+0.6x\\\\\Rightarrow\ 160=1.6x\\\\\Rightarrow\ x=\dfrac{160}{1.6}\\\\\Rightarrow\ x= 100$

Hence, the wholesale cost of the bike = $100

If x and y vary directly, and x = 12 when<br> y = 4, what is the value of x when y = 1 ?

zvonat [6]

When y = 4, x = 12...that means x is 3 times bigger than y. So if y = 1, then x will now = 1 x 3 = 3

3x+2y=46 x+y=17 how u solve

taurus [48]

Answer: (12, 5)

Step-by-step explanation:

3x + 2y = 46 x + y = 17

Subtract y from both sides of the equation.

x = 17 − y 3x + 2y = 46

Replace all occurrences of x with 17 − y in each equation.

51 − y = 46

x = 17 − y

Solve for y in the first equation.

Move all terms not containing y to the right side of the equation.

Subtract 51 from both sides of the equation.

−y = 46 − 51

x = 17 − y

Subtract 51 from 46.

−y = −5

x = 17 − y

Multiply each term in −y = −5 by −1

Multiply each term in −y = −5 by −1. (−y) ⋅ −1 = (−5) ⋅ −1

x = 17 − y

Multiply (−y) ⋅ −1.

y = (−5) ⋅ −1

x = 17 − y

Multiply −5 by −1.

y = 5

x = 17 − y

Replace all occurrences of y with 5 in each equation.

Replace all occurrences of y in x = 17 − y with 5. x = 17 − (5)

y = 5

Simplify 17 − (5).

Multiply −1 by 5.

x = 17 − 5

y = 5

Subtract 5 from 17.

x = 12

y = 5

The solution to the system is the complete set of ordered pairs that are valid solutions.

(12, 5)

The result can be shown in multiple forms.

Point Form: (12, 5)

Equation Form: x = 12, y = 5
