X+2=2y then x = 2y - 2
3x-3 = 5y +1
substitute x = 2y - 2 into 3x-3 = 5y +1
3x-3 = 5y +1
3(2y - 2) -3 = 5y +1
6y - 6 - 3 = 5y + 1
y = 10
x = 2y - 2
x = 2(10) - 2 = 18
x = 18 y = 10
answer C. x = 18 y = 10 (Third choice)
Answer:
2/5
Step-by-step explanation: Total outcomes=5
favourable outcomes=2
Therefore ,P(E)=2/5
To ask how much Mr. Perkins will have after 2 years is asking for the total or the "A".
Principle (P) - initial investment - $120
Interest rate (r) - 5% => 0.05
Term / time period (t) - 2 years
Interest (I) - amnt. after everything is multiplied
I = Prt
A = I + P
Interest = 120 × 0.05 × 2
Total = I + 120
Interest = $12
A = 12 + 120
A = $132
---------------------------------------------
Answers :
Interest : $12 after 2 years
Total after 2 years : $132

Answer: October, the 10th month
Step-by-step explanation:
540/12 = 45[with this in mind , we can assume that this is how many people get infected per month, except for July, and some factors.]
July is special for it not only has the specific unqiue rate of 5.2 infections per day. with this in mind, lets multiply....
And to top it off, we have another 225 infections to consider.
So with consideration of 161.2, 225, 540, and the fact that 45 people get infected on an average month, lets add....
161.2 + 225 + 540 = 926.2
926.2 + 45 = 971.2
971.2 + 45 = 1016.2
It only took until the 10th month of october to hit 1000.
