Answer:
-10
Step-by-step explanation
You subtract 4 by 4 which is zero. then you subtract 2 making it -2. You multiple 5 by -2. X is equal to -10.
Answer:
Problem:
Solve x+y=7;x+2y=11
Steps:
I will try to solve your system of equations.
x+y=7;x+2y=11
Step: Solvex+y=7for x:
x+y+−y=7+−y(Add -y to both sides)
x=−y+7
Step: Substitute−y+7forxinx+2y=11:
x+2y=11
−y+7+2y=11
y+7=11(Simplify both sides of the equation)
y+7+−7=11+−7(Add -7 to both sides)
y=4
Step: Substitute4foryinx=−y+7:
x=−y+7
x=−4+7
x=3(Simplify both sides of the equation)
Answer:
x=3 and y=4
Answer:
18.6
Step-by-step explanation:
We are given that
We have to find the value of k.
Divide by 32 on both sides then we get
Taking ln on both sides then we get
Hence, the value of k=18.6
I’m confused on this where is x??
