Answer: 3x=3
Step-by-step explanation: Let's divide this into parts--
1. Adding the x variables: -2x+5x or 5x-2x = 3x.
2. Adding the y variables: y-y or -y+y = 0. (The negative and the positive y cancel each other out.)
3. Adding the numbers: 8-5 or -5+8 = 3.
Now just put it back into an equation: 3x + 0 = 3.
We don't need to add the 0, so the equation changes into 3x = 3.
Answer:3,570
Step-by-step explanation: The 7 is over 5 so u know, 5 or more up the score. 4 percent or less let it rest.
Do a proportion
8/100= x/70
Cross multiply and divide
70 x 8= 560
560 divided by 100= 5.6
Answer is 5.6
You also could have done .08 x 70 which is also 5.6
Answer: 325/790 rounded to the nearest hundredths place is <em>0.41</em>
Step-by-step explanation:
if you divide 325/790 you get 0.411 and some other numbers. We only need to focus on these 3 numbers. 4 is the tenths place value and the first 1 is in the hundredths place value. Sense the second 1 (which is in the thousandths place value) is less than 5, we don't round the 1 in the hundredths place value up. Meaning your answer is 0.411.
Hopefully this makes sense.
