Answer:
50 pounds = 22.7 kilograms
Step-by-step explanation:
Yes both are correct
Sabine :
2.2 pounds = 1 kilogram
1 pound = 1/ 2.2 kilogram = 0.454 kilogram
50 pounds = 50 * 0.454 =22.7 kilograms
<u>Answer</u>:
x = 5
<u>Explanation</u>:
If the angle are parallel:
step 1:
21x + 7 = 22x + 2
21x - 22x = 2 -7
-x = -5
x = 5
finding upper angle, then when both lies on straight line equals to 180°
step 2:
180 = (180 - 22x - 2 ) + 21x + 7
180 = 180 - 2 + 7 - 22x + 21x
180 = -x 185
-5 = -x
x = 5
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.
