Answer:
7
Step-by-step explanation:
2n + 4n = 6n, adding like terms
6n = 42
6n/6 = 42/6
n = 7
Answer:
24+48+10+14+4=100
10+4=14
14/100, or 7/50 chance
Step-by-step explanation:
Experimental probability is the result of an individual experiment, not theoretical probability
Answer:
C
Step-by-step explanation:
If we know that x is greater than or equal to 4, then we should substitute 4 in place of x in each possible solution.
A 4 + 3 ≥ 1 True, it's greater, but it can't be equal to.
B 3(4) ≥ 1 It's greater once again, can't be equal to.
C 4 - 3 ≥ 1 If x can also be greater than 4, then it works both ways. Equal and greater than.
<u>Answer</u>:
Option 5: -4 ≤ 7x - 7 ≤ 4
<u>Step-by-step explanation:</u>
It is required to find which expression is equivalent to |7x-7| ≤ 4
So, at the beginning we should review the rules of absolute value inequalities.
1) If |x| ≤ a ⇒ -a ≤ x ≤ a
2) If |x| < a ⇒ -a < x < a
3) If |x| ≥ a ⇒ x ≤ -a or x ≥ a
4) If |x| > a ⇒ x < -a or x > a
Applying the first rule to the given absolute value inequality:
|7x-7| ≤ 4 ⇒ -4 ≤ 7x-7 ≤ 4
So, the answer is option 5
