Answer:

11) x>18000 and 12) x<4

Step-by-step explanation:

Okey dokey this is really simple actually. The way to do problems like this is to first write out the equation as if there were an equal sign. (x=18000 or x=4). Then all you have to do is figure out which way to put the greater than / less than sign. To do that the open end should be facing the greater number. (Like an alligators mouth. He wants more food so he eats whatever number is bigger (and yes alligators eat numbers.. don't question my sanity :l  ).

So for number 11 you know that MORE than 18000 tickets were sold (whoa thats a lot of tickets). This means that the number of tickets sold (x) is GREATER than 18000. Therefore, x>18000.

Do the same thing for number 12. The number of students absent was LESS than 4. This means that 4 is bigger than the number of students absent. So, x<4.

YAY MATH!

ram is half his fathers age now. ten years ago he was one third his fathers age then what are their present ages
NeX [460]

x   -  Ram's age now

Ram is half his father's age now, so his father's age is two times Ram's age:

2x  - Ram's father age now

x - 10   -  Ram's age ten years ago

2x - 10    - Ram's father age ten years ago

ten years ago he was one third his father's age so his father's age was three times Ram's age:

2x - 10 = 3•(x - 10)

2x - 10 = 3x - 30

-10 + 30 = 3x - 2x

20 = x

2x = 2•20 = 40

Answer:

<u>Ram is 20 years old now, Ram's father is 40 years old now.</u>

1/7(x+21)=-6<br> answer ?
Talja [164]
(1/7) Multiplied By x is 1/7x And (1/7) Multplied By Positive 21 is 3. So It Will Then Change To 1/7x + 3 = -6.
Subtract 3 From Both Sides. Then The Equation Changes To 1/7x = -9
Then Since (1/7) Basically Means To Divide You Would Multiply By 7 On Both Sides And Then x Would Equal -63!(:
Then Can Plug In -63 Where x Is To Check Your Work! Hope I Helped!

The sum of two numbers is 53 and the difference is 11. What are the numbers?
vaieri [72.5K]
Let assume that the the two numbers are X and Y and that X is the large number.
According to the question, 
X + Y = 53 .................. Equation 1
then,  X = 11 + Y........... Equation 2
Substitute equation 2 into equation 1.
[11 + Y] + Y = 53
11 + 2Y = 53
2Y = 53 - 11 = 42
2Y = 42
Y = 42 / 2 = 21,
Therefore, Y = 21 [Small number].
According to equation 1, 
X +Y = 53
X + 21 = 53
X = 53 - 21 = 32.
Therefore, X = 32 [Big number].
