Answer:
b ≥
Step-by-step explanation:
The expression:
5b - b - 1 ≥ -11
Now to solve this problem, we must be aware of some rules of inequality.
When dividing or multiplying with a negative value, the sign of the inequality must change;
5b - b - 1 ≥ -11
4b - 1 ≥ -11
Add + 1 to both sides;
4b -1 + 1 ≥ -11 + 1
4b ≥ -10
Now divided both sides by 4;
≥
b ≥
Answer:
-2.5
Step-by-step explanation:
5b - b - 1 ≥ -11
4b - 1 ≥ -11
+1 +1
4b ≥ -10
4/4 -10/4
b ≥ -2.5

Answer:
D
Step-by-step explanation:
The rule of exponents
× =
Shows that when 2 powers with the same base are being multiplied then the exponents are added.
The probability is 1/4 This is because: Probability of first tails = 1/2 Probability of second tails = 1/2 Probability of first AND second tails = 1/2 * 1/2 = 1/4 This is also visible in the set of outcomes
3/8 times 2/5 is 6/40 or 0.15. Just multiply straight across
Answer:
12
Step-by-step explanation:
4(x-6)=24
4x-24=24
+24 +24
4x=48
x=12
I think it's 10 because 10 is a multiple of 10,2, and 5. 5x2=10 2x5=10 10x1=10. Hoped I helped:D
