What all the numbers that round to 50?

Answers

Answer 1
Answer: The numbers that you could round to 50 (when rounding to a number that ends in 0) would be 45, 46, 47, 48, and 49. If you are rounding a decimal number to a whole number, then any number between 49.5 and 49.9 would round up to 50. Hope this helped! :D

Jeff has 1/2 pizza left in the fridge . at breakfast he ate 1/3 of it. what fraction of the original pizza dose he have left for lunch?

Answers

Subtract 1/2 - 1/3

Convert into denominators of 6:

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

So he will have 1/6 of pizza left for lunch.
(1-1/2)=1/2
(1/2)-(1/3)=1/6
This leaves Jeff with 1/6 of the original pizza.

Find the solution for -0.5x-3.69 = x -1.9 -2.39.a) x=0.4
b) x= -0.4
c) x=2.5
d) x= -2.5​

Answers

Answer:

a)x=0.4

Step-by-step explanation:

-0.5-3.69=x-1.9-2.39

-3.69+1.9+2.39=x+0.5x

-3.69+4.29=1.5x

0.6=1.5x

x=0.6/1.5

x=0.4

- 0.5x - 3.69 = x - 1.9 - 2.39

Transpose the values

- 0.5x - x = 3.69 - 1.90 - 2.39

Evaluate

- 1.5x = 3.69 - 4.29

- 1.5x = - 0.6

x = ( - 0.6)/( - 1.5) * (10)/(10)

x = (6)/(15) = (2)/(5)

or

Answer: a)

x = 0.4
