To solve for You first need to find a common denominator.
To do so, you need to make both denominators 10 by multiplying the top and bottom of by 5
= Reduce by dividing both the top and bottom by 2
Your answer is
The answer is 0.4 that is what i got
Last year a large trucking company delivered 9.0 x 105 tons of goods with an average value of $17,000 per ton. What was the total value of the goods delivered? Write the answer in scientific notation
Answers
So, we have 9×105 tons of goods. Which gives us a total of 945 tons.
These goods have the average value of 17000 per ton. When we turn that into an equation we got:
When we convert that into scientific notation, we can write that as:
On average, Jenny does five loads of washing per week. She buys a 1.2k box of Kapow! laundry powder. and can only use 60g a loadHow many weeks should the box of powder last for Jenny?
Answers
Given: 5 loads of washing per week 1.2kg box of laundry detergent 60 g per load.
convert 1.2 kg to grams. 1 kg = 1000 grams
1.2 kg * 1,000g/1kg = 1,200 g 1,200 g / 60 g per load = 20 loads 20 loads / 5 loads per week = 4 weeks
It would take 4 weeks for a 1.2 kg box of Kapow! laundry powder to last.
4x – 6x combining like terms
Answers
Answer: -2x
Step-by-step explanation: Very easy maths. Just add 4x + -6x, which is -2x. There's your answer.
since both of the X is to the power of one. You can act as if they’re imaginary. do 4 - 6 which equals -2. then your answer would be -2x.
