<h3>Option B</h3><h3>Multiply first equation by -2 and second equation by 3, solution (1, 1)</h3>
<em><u>Solution:</u></em>
<em><u>Given system of equations are:</u></em>
3x - 5y = -2 -------- eqn 1
2x + y = 3 ------- eqn 2
We have to solve the system of equations
Multiply eqn 1 by -2
-6x + 10y = 4 ------- eqn 3
Multiply eqn 2 by 3
6x + 3y = 9 -------- eqn 4
Add eqn 3 and eqn 4
-6x + 10y = 4
6x + 3y = 9
( + ) ------------
13y = 13
y = 1
Substitute y = 1 in eqn 2
2x + 1 = 3
2x = 2
x = 1
Thus solution is (1, 1)
Thus option B is correct

Answer:
0.3339 = 33.39% probability that both Dave and Mike will show up
Step-by-step explanation:
Probability of independent events:
If A and B are independent events, the probability of both happening at the same time is given by:
In this question:
Event A: Dave shows up.
Event B: Mike shows up.
Christine knows that there is a 47% chance that Dave will not show up and a 37% chance that Mike will not show up.
This means that .
a. What is the probability that both Dave and Mike will show up
0.3339 = 33.39% probability that both Dave and Mike will show up

Answer: RQS= 90, QRS= 43, QSR= 47
Solving Steps:
180-90=90 (all the angles combined equal 180)
9x-2+10x-3=90
19x-5=90
19x=90+5
19x=95
x=5
9(5)-2= 43
10(5)-3= 47
