Answer: x = 4

Step-by-step explanation: 48 divided by 12 = 4

4 x 4 = 16

Y = 8x

8 x 4 = 32

32 + 16 = 48

Answer: x=4, y=32

Step-by-step explanation:

y=8x

4x+y=48

Plug in 8x for y in the equation

4x+8x = 48

Add like terms

12x= 48

Divide both side by 12

12x/12=48/12

x= 4

Then plug 4 back into the original equation in place of x

4(4)+y=48

16+y=48

Minus 16 from both sides

y= 48-16

y= 32

Answer: (4,32)

Answer:

±6

Step-by-step explanation:

Given the mathematical expression;

√36 < √42 < √49

But, √36 = 6 * 6 = 6²

√49 = 7 * 7 = 7²

Simplifying further, we would substitute the new values respectively;

±[6] < √42 < ±[7]

Therefore, evaluating √36 is equal to ±6.
