Verbal expression for 5^2

4a^5-2a^5+4b+b How to combine this into likewise terms (^number stands for exponents) need help today pls!!!

Nat2105 [25]

Answer: 2a^5+5b

Step-by-step explanation:

This is actually pretty simple

The exponent with the same power can be subtracted so

4a^5-2a^5 is 2a^5 like 4x-2x which is equal to 2x

4b+b is equal to 5b

2a^5+5b is your answer

- In 1927, Charles Lindbergh had his first

Hitman42 [59]

Answer:

Each hour he fly 107.76 miles

Step-by-step explanation:

we know that

Charles Lindbergh flew 3,610 miles in 33.5 hours

To find out the unit rate, divide the total distance by the total time

so

$\frac{3,610}{33.5}= 107.76\frac{miles}{hour}$

therefore

Each hour he fly 107.76 miles

Look at the table of values below.

Natalka [10]

Answer:

A. y = 1 - 2x

The equation y = 1 - 2x is represented by the table.

Step-by-step explanation:

In this question you are trying to find out which is the right equations that belongs to the table of values.

For any streight line, you need the minimum of two points (x,y) to be able to draw a line that accounts for all points on that line...

If you substitute x = 1 in any of the equations, the outcome should be -1 because that is given in the table.

So try it and you will you find solely based on one of the first value that, the equations in A. and C. could be valid, because the point with coordinates (1, -1) is on the line A. and also on C.

At this time you can totally discard equations B an D because the value of y = -1 is not the outcome if you substitute x = 1. You can absolutely cross out answers B an D. Please understand what a timesaver this is; for the next substitution you only need to subsymtitue one extra coordinate (x,y) and you only have to substitute it only in equations A and C.

Try one more point, to choose between answer A and answer C. Just pick the easiest value in the table.

Please understand that you could pick eighter the x value OR YOU COULD choose the y value. It just does not matter, because the coordinate (x,y) is a pair of two numbers which are bound together by the equation given and also by all values in the table... The question remains, how fast can you distinguish which is the right equation....

After substituting another value from the table, you find that only equation A. is valid and not C (and you already discarded answers B an D remember)....

So the equation y = 1 - 2x is represented by the table, which is answer A.

Although this is a lot of text explaining the simple steps of substituting a value of the table an checking if the coordinate is a member of the equation, I hope it will save you a lot of time in the future!

Your class has 18 students. Exactly 23

Rama09 [41]

Answer:

Sample model as the picture attached, which shows 2/3 of 18 are circled.

Step-by-step explanation:

Here is the correct question: Your class has 18 students. Exactly 2/3

of them say that, out of all their subjects, they like science the most. Which model shows 2/3 of 18 circled?

Given: Total number of student is 18.

2/3 of the total students like science the most.

Now, calculating the number students like the science the most.

∴ Number of students who like the science most= $\frac{2}{3} \times 18= 12 \ students$

12 students like the science most out of total students.

Sample model are shown in the picture attached, where out of 18 students only 12 are inside the circle to show they like science the most.

13=1/4(2x+16) solve for x in simplest form

Pavel [41]

Answer:

18

Step-by-step explanation:

1/4 (2x+16) = .5x+4

13=.5x+4

-4 -4

9=.5x

9/.5 . .5x/.5

18=x
