Answer:
Dividing by 3 means splitting a number into 3 numbers, all equal. The division sign can be represented by a /.
For example, 12/3=4. We can check our answer by multiplying our answer by 3, and seeing if we get our original answer.
4*3=12
Division is the opposite of multiplication, so it makes sense that multiplication is a valuable tool to check our work.
Hope this helps!
Answer:
A rational number is a number that can be written as a ratio of two integers a and b, where b is not zero. For example, 4/7 is a rational number, as is 0.37 because it can be written as the fraction.
Step-by-step explanation:
x + (x + 3) + 
= 75
so you will add up all of the x 's but NOT the x^2
2x + 3 + = 75
Rearrange to put the x^2 in front of 2x
+ 2x + 3 = 75
subtract the 75 from both sides
+ 2x - 72 = 0
150 divided by 25 equals 6. 6 times 3 equals 18. This means that you will spend $18 on gas each week.
20+7 + 30+3 is that what you meAN
