can someone plzz tell me whichone is true. just but down the number when u answer back plzz & thank you
1. 14+(-25)> -50=
2. 20*10^3
3. 3/4 + 3/4> 1
4. 6^2=2^6
5. -21-(-39)=60
6. 19
7. 11*11*11 = 33^3
8. 38<7^2-(-20)
9.-5=20+(-25)
PLEASE HELP ME!!!!
Aren't 2 and 6 both true?
Sure, I can help you determine which statements are true or false. Let's analyze each statement one by one.
1. 14 + (-25) > -50
To simplify this, add 14 and (-25): 14 + (-25) = -11.
Therefore, the statement becomes -11 > -50, which is true. So, Statement 1 is true.
2. 20 * 10^3
Here, 10^3 means 10 raised to the power of 3, which is 1000. Therefore, 20 multiplied by 1000 is 20,000. So, Statement 2 is true.
3. 3/4 + 3/4 > 1
To add fractions, you need a common denominator. The common denominator here is 4. So, it becomes (3 + 3)/4 > 1.
Simplifying, 6/4 > 1, which is true since 6/4 is equal to 1.5. So, Statement 3 is true.
4. 6^2 = 2^6
To evaluate these exponents, 6^2 means 6 raised to the power of 2 (6 squared), which is 36. Similarly, 2^6 means 2 raised to the power of 6, which is 64.
Since 36 is not equal to 64, Statement 4 is false.
5. -21 - (-39) = 60
To subtract a negative number, change the sign and perform addition. So, -21 - (-39) can be rewritten as -21 + 39.
-21 + 39 = 18, which is not equal to 60. Hence, Statement 5 is false.
6. 19
Based on the provided question, where no equation or condition is mentioned, it seems that Statement 6 is neither true nor false. It's just the number 19.
7. 11 * 11 * 11 = 33^3
First, calculate 11 multiplied by 11: 11 * 11 = 121.
Then, multiply 121 by 11: 121 * 11 = 1331.
So, 11 * 11 * 11 is equal to 1331, and 33^3 is also equal to 1331. Therefore, Statement 7 is true.
8. 38 < 7^2 - (-20)
To evaluate this expression, first solve the exponent: 7^2 = 49.
Then, solve the subtraction: 49 - (-20) = 49 + 20 = 69.
Finally, compare 38 with 69. Since 38 is less than 69, Statement 8 is true.
9. -5 = 20 + (-25)
To add two numbers with different signs, subtract the smaller absolute value from the larger one.
Here, 20 has a greater absolute value than -25, so subtract 25 from 20: 20 - 25 = -5.
Hence, -5 is equal to -5, making Statement 9 true.
So, to summarize:
True statements: 1, 2, 3, 7, 8, 9.
False statements: 4, 5.
Uncertain: 6 (it's just the number 19).
