Solve the system 8y-5z=23 3y-2z=6<br><br> 100 POINTS

Hatshy [7]

Answer:

z = 21 ; y= 16

Step-by-step explanation:

first of all we have to isolate a variable.

In second expression we can obtain:

3y = 2z+6

y = 2/3 z + 2

now we have to substitute this value in the first equation and solve it

8(2/3z+2)-5z = 23

16/3z + 16 -5z = 23

16z +48 - 15z = 69

z = 21

now we have to substitute z in the second equation:

y = 2/3 (21) +2

y = 14+ 2 = 16

y = 16

Which expression will determine the perimeter, in inches, of the rectangle? O 10 x 7 10 + 7 O (2 x 7) + (2 x 10) O 10 x 7 x 7 x

fredd [130]

Answer:

$(2 * 7) + (2 * 10)$

Step-by-step explanation:

The missing details in the question are:

$Length = 10$

$Width = 7$

Required

The perimeter

This is calculated as:

$Perimeter = 2 * (Length + Width)$

So, we have:

$Perimeter = 2 * (10 + 7)$

Open bracket

$Perimeter = 2 * 10 + 2 * 7$

Rewrite as:

$Perimeter = (2 * 7) + (2 * 10)$
