How do you simplify 2/3 divided by 1/3
suter [353]

Answer:

2

Step-by-step explanation:

Solve. To do so, change the division sign into a multiplication sign, and flip the second fraction:

(2/3)/(1/3) = (2/3) x (3/1)

Multiply across:

(2 * 3)/(3 * 1) = (6)/(3)

Simplify:

6/3 = 2

2 is your answer.

Given the equation y = 4x - 3.A) If x increases by 1 unit, what is the corresponding change in y? B) If x decreases by 5 units,
DedPeter [7]

Answer:

A) y will increase by 4 unit.

B) y will decrease by 20 units

Step-by-step explanation:

Given equation that shows relation between x and y.

y=4x-3

A) If x is increased by 4 units

   New value of  y =  4(x+1)-3

                              =4x+4-3

                              =4x+1

So, change in y = new value of y- original value of y

                         =4x+1-(4x-3)

                          =4x+1-4x+3

                          =4

Thus, the value of y will be increased by 4 units.

B) If x is decreased by 5 units

   New value of  y =  4(x-5)-3

                              =4x-20-3

                              =4x-23

So, change in y = new value of y- original value of y

                         =4x+1-(4x-3)

                          =4x-23-(4x-3)

                          =4x-23-4x+3

                          = -20

Thus, the value of y will be decreased by 20 units.

Jerritt wants to buy a car but it costs
o-na [289]

Answer:

47 weeks

Step-by-step explanation:

you multiply 20 times 5 because he makes 5 dollars and hour and works 20 hours a week, so then you get 100. so he makes 100 dollars in a week. then you divide 100 by 4650 and get 46.5 which rounded up is 47. so he needs to work 47 weeks.
