Answer:
Option A: Madison, (1.2,-1.6) is the correct answer.
Step-by-step explanation:
Observing Madison's solution it can be seen that he has used elimination method to solve the system. If elimination method has to be used the first equation has to be multiplied by 4
While Madison has made mistake with sign of one term in equation 1 (he has written -8x instead of 8x)
So <u>Madison's solution is wrong. </u>
Tyler has used the substitution method to solve the system of equations and has done it correctly (Calculated value of y in terms of x from equation 1 and substituted in equation 2)
The value of x=1.2 is correct, we have to find the value of y
So,
Putting the value of x=1.2 we get,
The solution of given system of equations is (1.2,-1.6)
Hence,
Option A: Madison, (1.2,-1.6) is the correct answer.
Answer:
The required answer is 5790 meters in 1 minute.
Step-by-step explanation:
Consider the provided information.
193 meters in 2 seconds = meters in 1 minute
193 meters in 2 seconds can be written as:
193 meters = 2 seconds
There are 60 seconds in 1 minute. To convert 2 seconds to 1 minute multiply both the sides by 30.
30 × 193 meters = 30 × 2 seconds
5790 meters = 60 seconds
5790 meters = 1 minute (As we know 60 seconds = 1 minute)
This can be written as:
5790 meters in 1 minute.
Hence, the required answer is 5790 meters in 1 minute.
Hello!
-x / 4 + 5 = -3
Subtract 5 from both sides
-x / 4 = -8
Multiply both sides by 4
-x = -32
Since x is negative we can multiply both sides by -1 to make x positive
x = 32
The answer is 32
Hope this helps!
Answer:
2
Step-by-step explanation:
2 square root 10.
4 is a perfect square that enters 40. 4*10 is 40. So square root of 4 is 2. So it would be 2 square root 10 since there isn’t a perfect square that goes int 10
