Answer:

93

Step-by-step explanation:

Follow PEMDAS you would multiply 2 ⋅ 4 first (but I don't think it really matters in this case)

So your equation would look like this now:

((11 - 3)8 - 13 + 42

11 - 3 = 8

8 ⋅ 8 - 13 + 42

8 ⋅ 8 = 64

64 - 13 + 42

64 - 13 = 51

51 + 42 = 93

Hope I helped :)

Y=-5x+6<br> y=3x-2<br><br> Find the solution to the system of equations.
Kobotan [32]

Answer:

(1, 1 )

Step-by-step explanation:

Given the 2 equations

y = - 5x + 6 → (1)

y = 3x - 2 → (2)

Since both equations express y in terms of x, equate the right sides

3x - 2 = - 5x + 6 ( add 5x to both sides )

8x - 2 = 6 ( add 2 to both sides )

8x = 8 ( divide both sides by 8 )

x = 1

Substitute x = 1 into either of the 2 equations for corresponding value of y

Substituting x = 1 in (2)

y = 3(1) - 2 = 3 - 2 = 1

Solution is (1, 1 )

What is the value of y ?
Galina-37 [17]
The rhombus has four equal sides ⇒  JK=ML=KL
4x-8 = x+13
4x - x = 13 + 8
3x = 21
x = 7
ML = x+13 = 7 + 13 = 20

KL=ML ⇒
6y+2 = 20
6y = 20-2
6y = 18
y = 18/6
y = 3
