Reduce the numbers with greatest common divisor 3
1/5 times 2
Calculate the product
2/5
Let's solve your system by elimination.
8x+y=−16;3x−y=5
8x+y=−16
3x−y=5
Add these equations to eliminate y:
11x=−11
Then solve: 11x=−11 for x:
11x=−11
11x
11
=
−11
11
(Divide both sides by 11)
x=−1
Now that we've found x let's plug it back in to solve for y.
Write down an original equation:
8x+y=−16
Substitute: −1 for x in 8x+y=−16:
(8)(−1)+y=−16
y−8=−16(Simplify both sides of the equation)
y−8+8=−16+8(Add 8 to both sides)
y=−8
Answer:
x=−1 and y=−8
Answer:
72%
Step-by-step explanation:
A circuit contains two switches.
The first switch transmits messages correctly 80% of the time, then the probability that the message will be transmitted successfully through the first switch is

The second switch transmits messages correctly 90% of the time, then the probability that the message will be transmitted successfully through the second switch is

The probability that the message will be transmitted successfully through both switches is

that is exactly 72%
Answer:
Yes it is, because when you plug it in, it works
Step-by-step explanation:
y = 4x
y = 4*2 = 8 which makes sense
