Answer:
B
Step-by-step explanation:
because the denominator of fraction, 5/12 ,is greater than both the numerator and the multiplier which is 7
Answer:
-7(a + 2b + 4)
Step-by-step explanation:
-7a - 14b - 28
⇒ -7(a + 2b + 4)
Answer:
I think it's x=-12 for the buttom one
Step-by-step explanation:
I think when you get open equations like these you would asume 1 is there so rewrite it as 2x + 25 = 1
so take the 25 away from 1. to do that we need to do the opisite of +
2x + 25 = 1
1 - 25 = -24
rewrite
2x = -24
take the 2 away. oppisite of mulitplication is division. so divide 2 by -24
-24 divided by 2 = -12
Hope this helps! Please mark as brainliest! Thanks! If you need me to solve the top one too, I'll do it! Just comment bellow. :D
Add the numbers: 3+17 = 20
-x + 5 < -1/20
Apply the fraction rule: -a/b = - a/b
-x + 5 < - 1/20
Subtract 5 from both sides
-x + 5 - 5 < 1/20 - 5
Simplify
-x< - 101/20
Multiply both sides by -1 (reverse the inequality)
(-x) (-1) > (-101/20) (-1)
x> 101/20 is the final answer
Answer:
So, to work with negative exponents you need to multiply like a positive exponent, and move the decimal over double the digits place each time.
Examples:
If it is 4 with an exponent of -2, then you will multiply 4 by 4 to get 16, and then move the decimal over double the amount of digits. There are two digits, so you will move the decimal over four digits.
So the answer to 4 with an exponent of -2 would be .0016.
