Answer:

k= 112

Step-by-step explanation:

12y = 7z

y= 7z/12

_________

3x =8y

3x= 8× 7z/12

3×=56z/12

36x=56z

x=56z/36

_________

zk=72x

zk= 72 ×(56z/36)

k= (72×56)/36

k=112

marin [14]

Answer:

option.D

Step-by-step explanation:

each day it changes by $-73\frac{1}{4}$

so for two days , the elevation becomes $-73\frac{1}{4}$ + $-73\frac{1}{4}$

for 3 days : $-73\frac{1}{4}$ + $-73\frac{1}{4}$ + $-73\frac{1}{4}$

so, for n days, $-73\frac{1}{4}$ + ........ n times

= n* $-73\frac{1}{4}$

therefore, for x days, elevation = x* $-73\frac{1}{4}$

as it is given that after certain days this elevation has reached $-366\frac{1}{4}$

so, x* $-73\frac{1}{4}$ = $-366\frac{1}{4}$

What is the answer to the main problem

Sholpan [36]

Answer:

x-int: (3, 0)

y-int: (0, -1.5)

Step-by-step explanation:

x-intercept is the x-value when y = 0

y-intercept is the y-value when x = 0

Step 1: Find x-intercept

0 = (x - 3)/2

0 = x - 3

x = 3

(3, 0)

Step 2: Find y-intercept

y = (0 - 3)/2

y = -3/2

(0, -1.5)
