4x+10y=-13...you have to add the variables that are the same and then subtract the 13 from 0
28 = k - 12
28 + 12 = k
40 = k
2x + y = 7
y = -2x + 7 where slope m = -2 and b= y intercept = 7
Answer is C
slope : -2 and y intercept = 7
Answer:
x=25
Step-by-step explanation:
2x+40=90
90-40=50
50 divided by 2 is 25
x=25
We have that
the total <span>sold tickets is -------------------------- >600
</span>
the probability of winning with 1 ticket
<span>P=1/600=0.001667---------------- > 0.17%
</span>the probability of winning with 8 ticket
P=(1/600)*8=0.0133---------------- > 1.33%
<span>
the answer is </span>1.33%<span>
</span>
