Answer:

x = 45 / 8

Step-by-step explanation:

8 x - 3 y = 36

8 x - 3 × 3 = 36 ( given :- y = 3 )

8 x - 9 = 36

add 9 to both side

8 x - 9 + 9 = 36 + 9

8 x = 45

Divide each side by 8

8 x / 8 = 45 / 8

X = 45 / 8

Answer:

x = 45/8

Step-by-step explanation:

8x – 3y = 36

Let y=3

8x – 3*3 = 36

8x - 9 = 36

Add 9 to each side

8x -9+9 = 36+9

8x = 45

Divide each side by 8

8x/8 = 45/8

x = 45/8

Fofino [41]

23 ^ (-2) is equal to 1 / (23^2). 23 to the second power is equal to 529. Thus, the answer would be 1/529. None of the answers are correct. 8 squared is 64.

Identify if each number sentence is true or false? (show your work)

Step2247 [10]

(27)

we are given

$5x+34$

we need to check for x=12

so, we can plug x=12

$5*12+34$

$60+34$

$94$

we know that 94 is always greater than 54

so, this is FALSE

(28)

$8.5\leq s-12$

we have to check at s=20.5

we can plug it

$8.5\leq 20.5-12$

$8.5\leq 8.5$

we know that

8.5 is equal to 8.5

so, this is TRUE..........Answer
