Answer:
for for A,
16+7+5+12 = 40
the probability of throw the darts is 5/40
if there were 80 people doing it, an estimate of 10 people would do throw the darts
Answer: 8 friends
Step-by-step explanation:
35(at first)-3(left)=32
32(given away) divided by 4(to each friend)= 8 friends
4b - 7 + 2b + 11 and b + 3 + b + 1 are congruent.
You add the common factors in each problem: 2b + 4 = 2b + 4
Answer:
1
Step-by-step explanation:
Answer:
(1,2) and (2,-1)
Step-by-step explanation:
we have
----> inequality A
The solution of the inequality A is the shaded area below the dashed line 
---->inequality B
The solution of the inequality B is the shaded area above the dashed line 
The solution of the system of inequalities is the triangular shaded area between the two dashed lines
If a ordered pair is a solution of the system of inequalities, then the ordered pair must lie on the shaded area
Two points in the solution are(1,2) and (2,-1)see the attached figure
