The sum of two numbers is 8, and their difference is 22

Mathematics
1 answer:
lawyer [7]4 years ago
8 0

Answer:

15, -7 x=15 y=-7

Step-by-step explanation:

x+y=8, we'll come back to this

x-y=22, move y to the other side, x=y+22

now insert the value of x =(y+22) to the other equation like so, (y+22)+y=8, simplify

2y+22=8 2y=(-14), y=(-7)

Insert the value of y into the first equation again like so, x+(-7)=8, simplify

x=15

15, -7

Please help me. I really need help
Flauer [41]
A. 38

Let X = seventh graders

6th graders are twice the number of 7th graders; therefore, 6th graders will be 2X.
The total number of students is 57.

2X + X = 57
3X       = 57
X         = 57 / 3
X         = 19

IF X represents the 7th graders; there are 19 seventh graders present.
Since 6th graders are represented by 2X; Then, 2 * 19 = 38 is the number of 6th graders present.

Add both numbers to check: 19 + 38 = 57.

Just remember that 1 mile is equal to 5,280 feet.

If we have 5 miles, we need to multiply it my 5,280 which would equal 26,400.


Then we have the other 529 feet that they gave. Just add 26,400ft and 529ft and they will equal 26,929 ft.


Hope it helped! Remember, five tomatoes! (five two eight oh(0)).
