The sum of the digits of a two-digit number is 11. The number obtained by interchanging the digits exceeds twice the original number by 34. What is the original number?

Answers

Answer 1

Answer: cool problem

x and y are the digits
x+y=11
yx=2(xy)+34
I'm not sure how to solve this using legit math so use trial and error

the 1 digit numbers that could be possible are
9,2
8,3
7,4
6,5
5,6
4,7
3,8
2,9
all of them add up to 11

the pairs obtained by swiching the number are
92 and 29
83 and 38
74 and 47
65 and 56

we find which ones are equal when we subtract 34 from the larger number and divide by 2
92-34=58
58/2=29
92 and 29 work

83-34=49
49/2=24.5 not equal to 38 not work

74-34=40
40/2=20 47 not equal to 20 so doesn't work

65-34=31
31/2=15.5 not equal to 56 so doesn't work

the origonal number is 29

Raymond wants to make a box that has a volume of 360 cubic inches. He wants the height to be 10 inches and the other two dimensions to be whole numbers of inches. How many different-sized boxes can he make?

Answers

3 because 360/10 =36 so you have to find factors of 36 (not sure if factors is the right word) but they are :3&12,9&4,6&6

it depends on what the units are measured

1 cubic centimeter = 1 milliliter, so your 8cm cube is 8x8x8 = 512 cubic centimeters.
This would equate to a volume of 512 milliliters which is equal to just over 1/2 liter (0.512 liters).

Which inequality has the solution shown below?

Answers

The answer is 0.2x + 5 > 2

Answer:

0.2x + 5 > 2

Step-by-step explanation:

The arrow is pointing to the right so immediately you know that the sign will be greater than (>). So we can eliminate the choices, 0.3x + 8 < 3 and 0.4x +7 < 1.

Now looking at the two options that are left, we can simply solve them.

0.2x + 5 > 2

Subtract 5 on both sides

0.2x > -3

Then divide 0.2 on both sides and you're left with:

x > -15

We don't need to solve the other inequality because we know that the arrow is pointing to the right, suggesting that x is greater than -15.
