C if im right because 40 - 190 is 150 and she worked 3 hours 50 50 50 = 150
2^4x^11000000 would be the answer in scientific notation.
Answer:
Let's solve for x. x=2y
Step-by-step explanation:
Let's solve for x.
x−2y=0
Step 1: Add 2y to both sides.
x−2y+2y=0+2y
x=2y
Let's solve for y.
x−2y=0
Step 1: Add -x to both sides.
x−2y+−x=0+−x
−2y=−x
Step 2: Divide both sides by -2.
−2y/−2=−x/−2
y=1/2x
1m= 1000mm
so 64mm*1m/1000mm=64/1000m
