If anyone can do these or atleast like 3 I swear to god I’ll be eternally in your debt it should be pretty easy too, like 7th grade level stuff!

11) x = -5

12) x = -12

13) x = 6

14) y = -9

15) No solution

16) Infinite Solutions

Step-by-step explanation:

11)

5x + 10 = 3x

   -5x          -5x

10 = -2x

divide by -2

x  = -5

12)

6p + 4 = 5p - 8

    +8           +8

6p + 12 = 5p

-6p          -6p

12 = -1x

x = -12

13

3x - 22 = -8x + 44

    +22            +22

3x = -8x + 66

+8x   +8x      

11x = 66

x = 6

14

-11(k + 4) = 55

-11y - 44 = 55

      +44   +44

-11y = 99

y = -9

15

6(c - 8) = 5(2c - 12) - 4c

6c - 48 = 10c - 60 - 4c

6c - 48 = 6c - 60

    +48          +48

6c = 6c - 12

-6c  -6c      

No Solution

-12y + 21 = -3(5y - 7) + 3y

-12y + 21 = -15y + 21 + 3y

-12y + 21 = -12y + 21

both sides are the same, so

Plz mark as brainliest if this helped! Have a nice day!!!

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:

so a parallelogram is just like a square base times height. multiply 40 and 39 to get 1560 inches.

a triangle is base times height divided by two. so multiply 7.9 and 5 and then divide it by 2 to get 19.75inches.

the kite can be split into two separate triangles and added together to get the total area. 30 x 4 /2 which equals 60. make sure to double it for the two triangles making 120.
