Using substitution method 4x -2y = 18 -4x+2y= -18
dedylja [7]

x= 9
y= 9

4x -2y= 18.................equation 1

-4x + 2y= -18...............equation 2

From equation 1

4x= 18 + 2y

x= 18 + 2y/4

substitute 18+2y/4 for x in equation 2

-4(18+2y/4) -2y= 18

-(18+2y)-2y= 18

-18-2y-2y= 18

-18+4y= 18

4y= 18+18

4y= 36

y= 36/4

y= 9

Substitute 9 for y in equation 1

4x-2y= 18

4x-2(9)= 18

4x-18= 18

4x= 18+18

4x= 36

x= 36/4

x= 9

Hence the value of x is 9 and the value of y is 9

Illusion [34]

Answer:

If the bolt is .52, it is between .517 and .583, so it can go in the package.

Step-by-step explanation:

The first step is to determine what the error amount is

6% of .55

.06*.55 =.033

The bolt must be within .033 of .55

.55 - .033 = .517

.55 + .033 = .583


The bolt must be between .517 and .583 inches


If the bolt is .52, it is between .517 and .583, so it can go in the package.
