The sum of nine times a number and fifteen is less than or equal to the sum of twenty four and ten times the number

Answers

Answer 1

Answer: let x be the number, then
9x + 15 < or = 10x + 25
then this inequality can be solved
subtract 9x from both sides of < or =
15 < or = x + 25
subtract 25 from both sides of < or =
-10 < or = x
this can be written as
x > or = -10

Answer 2

Answer: The sum of nine times a number and fifteen is less than or equal to the sum of twenty four and ten times the number needs to be put down in an inequality.

$9x+15 \leq 24+10x$

Solve for x.

$-x \leq 9$
$x \geq -9$

Caitlin did 3/5 of the problems on her math test correctly and eight incorrectly. She did all the problems how many problems were there?.. How do you answer this??

Answers

We know that 3/5 of the answer is right and 8 are wrong. If we do 5/5-3/5, we get 2/5 which is the amount of problems that are wrong or in other 8 wrong.
3/5=?
2/5= 8 wrong
If we make 2/5 into 1/5 we get 4 wrong answer.
Then we multiply 1/5 and 4 by 5 we get: 5/5 and 20 problems.
So there is 20 problems on the test.

Answer: i think its the first one 2/3

Answer:

2/3

Step-by-step explanation:

it starts off as 2:3 right? so the 3 is light soy sauce. if you want to turn the right soy sauce into 1 cup you have to divide 3 bye 3 which gives you one. then you also divide by 3 on the other side. that would be 2 divided by 3. 2 divided by 3 is the same as 2/3. so your answer is 2/3.

Answers

standard form for scientific notatnio is
(number more than or equal to 1 and less than 10) times 10^x
maybe you want to multiply it out so
10^3=10 times 10 times 10=1000
basically, if positive, move the decimal place to the right the exponent number of spaces
if negative do move to the left

first one
4 times 10^9
4 with 9 zeroes after it
4,000,000,000
this is in standard form

2nd one
2 times 10^-5
move decimal place 5 places to the left
0.00002

3rd
3.7 times 10^6
6 places to the right
3,700,000

4th
3 times 10^8
8 zeroes
300,000,000

4000000000
