Ok so we have 2 equations here...
x + y = 76
1/3x + 1/2y = 34
First solve for x in the 1st equation...
x + y = 76
x = 76 - y
Now substitute 76-y for x in the 2nd equation...
1/3x + 1/2y = 34
1/3(76-y) + 1/2y = 34
76/3 - 1/3y + 1/2y = 34
-1/3y + 1/2y = 34 - 76/3
-2/6y + 3/6y = 34 - 25 1/3
1/6y = 8 2/3
y = 8 2/3 ÷ 1/6
y = 8 2/3 × 6
y = 52
Now substitute 52 into the 1st equation for y
x + y = 76
x + 52 = 76
x = 76 - 52
x = 24
The 2 numbers are 24 and 52.
The difference between the numbers is
52 - 24 = 28

Answer:
Draw a line from (3, -2) to (3, 4).
Step-by-step explanation:
(3, -2) part: Start from 0 and go to the right 3 times, then move 2 down and draw a point there. (3, 4) part: Start from 0 and go to the right 3 times then 4 up, draw a point on that location. Connect the dots from (3, -2) to (3, 4) in a line. Then your Finished!
Answer:
x= -1/4
Step-by-step explanation:
suppose ,
The number is x
now,
twice a number = 2 . x = 2x
The product of twice a number and six = 2x . 6 = 12x
[ "product" means the result of multiplication]
Then,
Eleven times the number = 11 . x = 11x
The difference of eleven times the number and 1/4 = 11x - 1/4
= (44x-1)/4
Hence,
12x = (44x-1)/4
=>48x = 44x-1 [multiplied by 4 on both sides]
=>48x-44x=-1 [subtract 44x on both sides]
=>4x=-1 [divide both sides by 4]
=>x= -1/4
8.12×10^5
... i got this by taking the first number 8 and then counting the places behind the 8 which would be 5 so than you move the decimal place by 5 so you get 8.12 then you show theirs 5 places behind the 8 by adding the 10^5 so youbget 8.12×10^5
