Answer: (0, -3)
Step-by-step explanation:
Add both equations to eliminate x
6x-4y=12
+ -6x+y=-3
-----------------
-3y = 9
y = -3
Substitute y=-3 into the second equation:
-6x=(-3)=-3
-6x=0
x = 0
Therefore, the ordered pair of solutions is (0, -3)
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>
8-6z=26
8-8-6z=26-8
-6z=18
divide by -6 for -6z and 18
-6z/-6=18/-6
z=-3
Check answer by using substitution method
8-6(-3)=26
8+18= 26
26=26
Answer is z=-3
Answer:
First number: 15
Second number: 21
Third number: 84
Step-by-step explanation:
To figure out which sold the most magazines, multiply each number by 200 to find the answer. Let's start with 1/8. 200 * 1/8 = 25. Then 0.065 * 200 = 13.
3/100 * 200 = 6
200 * 0.105 = 21.
Fatima sold the most magazines.
