50x + 2.50 = 120.
x = how many tables she cleans to get $120.
Answer:
Step-by-step explanation: To divide by a decimal, multiply the divisor by a power of ten to make the divisor a whole number. Then multiply the dividend by the same power of ten. You can think of this as moving the decimal point in the dividend the same number of places to the right as you move the decimal point in the divisor.
the answer choices don't make sense but I can help u with solving the equation it's x = 1
- 3x-12=-9 , minus 12 on both sides
- 3x = 3 , divide 3 on both sides
- x = 1
now that u know this go through your answer choices and solve their equation and see which one produces x = 1 and that'll be the answer!!
