One number is 5 more than twice another and their sum is 23. which of the following system of equations represents the word problem? x + y = 23 and y = 2x + 5 y = x + 5 and y + 2(x + 5) = 23 y = 2(x + 5) and x + y = 23

x+y = 23

y = 2x + 5

Step-by-step explanation:

One number is 5 more (Add 5) than twice another (2 times x)

y = 2x + 5

the sum is 23 so x + y = 23

x + y = 23 and y = 2x + 5 represents the word problem One number is 5 more than twice another and their sum is 23

Solution:

Given that One number is 5 more than twice another and their sum is 23

Let the two numbers be "x" and "y"

Where one number let it be x is 5 more than twice the another number y and sum of these number is 23

y = 5 + 2x   ….  (1)

Sum of numbers = 23

x + y = 23  …  (2)

Hence the above two equations x + y = 23 and y = 2x + 5 represents the word problem

stew reads at the fastest rate of 265 words per minute.

step-by-step explanation:

it's a given that felicia reads at 260 word per minute and on connie's graph we can see that she reads 200 words per minute. since stew's table tells us that he read 795 in 3 minutes, we can divide 795 by 3 to find out how many words he reads per minute.

795/3 = 265

stew reads 265 words per minute - he reads at the fastest rate since felecia reads at 260 words per minute and connie reads at 200 words per minute.

stew (265) > felecia (260) > connie (200)

a) one student is chosen from classroom a, then a student is chosen from classroom b.  

step-by-step explanation:

independent events are ones in which the probability of one event does not affect the probability of the second event.

one student is chosen from classroom a; this does not affect the chances of choosing a student from classroom b.   this makes these independent events.

when one card is chosen from a standard deck and then set aside before a second card is chosen, the probability of the second card being chosen changes.   this makes them dependent events.

when one student is chosen from classroom a and then a second student is chosen from classroom a, the probability of choosing the second student changes.   this makes them dependent events.

when a letter is chosen from the alphabet and then a second letter is chosen, the probability of choosing the second letter changes.   this makes them dependent events.
