Fifteen more than 3 times a number is 33. What is the equation and solve

kati45 [8]

Answer:

x = 6

Step-by-step explanation:

15 more represents “+15”

3 times a number represents “3*x” which is written as “3x”

So fifteen more than 3 times a number is 33 would be written as;

3x + 15 = 33

Now solve for x using algebra;

3x = 33 - 15

3x = 18

x = 18 / 3

Hope this helps!

What is the difference between -3 and 2 on the number line

Elan Coil [88]

Answer

The difference is -5

Because

In the number line

-3 is in the negative side and

2 is in the positive side

So difference means minus

So,

-3-2

=-5

Remember

- - = + (but the answer should have - sign)

- + = - (the greatest number's sign will be taken)

++ = -

+ - = -
