Answer:

x = 5

Step-by-step explanation:

9x + 3y + 4z = 24

9x + 3(9) + 4(-12) = 24

9x + 27 + (-48) = 24

9x + 27 - 48 = 24

9x - 21 = 24

9x = 24 + 21

9x = 45

x = 45 ÷ 9

x = 5

3y = 3 * 9 = 27
4z = 4 * -12 = -48
: -48 + 27 = -21
: -21 + x = 24
: X = 45.
I hope that makes sense.

Can you simplify 37/80
Setler [38]

Answer:

Step-by-step explanation:

37 is prime, so it's not possible to reduce/simplify 37/80.  37/80 is the ratio of two integers.  We could, of course, use a calculator to find the decimal equivalent:  0.4625, but this is not more accurate than the ratio 37/80.

1/3k+80=1/2k+120 what does k equal?
LenaWriter [7]

Answer:

k = -1/240

Step-by-step explanation:

to evaluate the value of k in the expression 1/3k+80=1/2k+120

we have

1/3k+80=1/2k+120

collect the like terms for easy evaluation

1/3k - 1/2k = 120 -80

1/3k - 1/2k = 40

find the lcm

2 - 3/6k = 40

-1/ 6k = 40

cross multiply

6k  x  40  = -1

240k = -1

divide both sides by 240

240k/240 = -1/ 240

k = -1/240

therefore the value of k in the expression 1/3k+80=1/2k+120 is equals to -1/240
