Answer:

x+15=3(x-5) his present ae is 15 years

Step-by-step explanation:

list the following rational numbers in order from least to greatest. -0.4 , 0.48, 4/8, -4/8. Someone plssssssss help me I need it for today.

Answers

For a problem like this, it is best to convert all numbers to a similar form making them easier to compare. I am going to convert them all to decimals, although converting them all to fractions can also work.
-0.4 is already a decimal, so it needs no conversion; the same goes for 0.48.
4/8 is equal to 1/2, which equals 0.5 as a decimal. -4/8 is the same as -1/2, which is -0.5.
Therefore, we are left with the following converted numbers:
-0.4; 0.48; 0.5; -0.5

Now to simply order them from least to greatest, we will start with the two negative numbers because they are both below zero. When comparing negative numbers, the "bigger" one is actually smaller because it is farther below zero. Therefore, -0.5 is the smallest, followed by -0.4.

Now for the last two, 0.5, or 0.50, is 0.02 bigger than 0.48. Therefore, 0.48 is the second largest number and 0.5 is the largest.

This is the order now:
-0.5 (smallest)
-0.4 (2nd smallest)
0.48 (2nd largest)
0.5 (largest)

Now they simply need to be converted back to their original form (if applicable):
-0.5 = -4/8
-0.4 = -0.4
0.48 = 0.48
0.5 = 4/8

This leaves us with the answer:
-4/8; -0.4; 0.48; 4/8

Which expression is equivalent to this expression? x(2x + 3) A) 2x2 + 3 B) 2x2 + 3x C) 2x2 - 3x Eliminate D) 3x + 3

Answers

Answer:

Step-by-step explanation:

x(2x + 3)

Expand the brackets.

x(2x)+x(3)

Multiply the terms.

2x² + 3x

The answer is 2x² + 3x.

Answer:

I believe it is B. 2x2 + 3x

Step-by-step explanation:

Because x will go into 2x like 2x^2 and if you multiply x * 3 which it would equal 3x. That's the best I can explain it.

Hope my answer has helped you and if not I am sorry.

Harold spent 3/4 hour milked 3 groups of cows. If he spent an equal amount of time on each group of cows, what fraction of an hour milking each group?

Answers

1/4 hour because since it took him 3/4 hr to milk 3 groups, it is reasonable to divide 3/4 by 3. So in 1/4 hour.
