Answer: 7/4

Step-by-step explanation:

you would first add 5 to both sides

4x-5+5= -12+5

then simplify

4x= -7

divide 4 on both sides

4x/4= -7/4

and you get x=7/4

Answer:

The answer to your question is:

x = 2

y = 4

Step-by-step explanation:

     4x - 5y = -12       (1)

      -x + 5y = 18        (2)

Solve the system

                                               4x - 5y = -12

                                                 -x + 5y = 18

                                              3x   + 0 = 6

                                               3x = 6

                                                  x = 6 / 3

                                                  x = 2

                  Substitution

                                     4(2) - 5y = -12

                                      8 -5y = -12

                                          -5y = -12 - 8

                                          -5y = -20

                                           y = -20 / -5

                                           y = 4

pickupchik [31]
1. Find area of hexagon
Number of sides(area of triangle)
(6)1/2(11)(9.5)=313.5
Multiply by 2 since there are two hexagons
=627

2. Find area of the 6 rectangles
Number of sides(area of rectangle)
(6)(11)(20)=1320

3. Add area of both hexagons and the rectangles
627 + 1320= 1947

Therefore, the surface area of this prism is 1947
