The quantity r varies jointly with t and u and inversely with s when t= -12, u= -7, and s= -4, r= -126. Find r when t= -8, u= 8,
vichka [17]

Answer:

r = 64

Step-by-step explanation:

r = (k*t*u)/s

Where,

k = constant of proportionality

t = -12,

u= -7,

s= -4,

r= -126.

r = (k*t*u)/s

-126 = (k*-12*-7)/-4

-126 * -4 = 84k

504 = 84k

k = 504/84

k = 6

Find r when t= -8, u= 8, and s= -6.

r = (k*t*u)/s

= (6*-8*8) / -6

= -384 / -6

= 64

r = 64

pentagon [3]

Question 1:

We are going to add.

1/5 + 1/2

2/10 + 5/10

7/10

Note that we are going DOWN so the number will be negative.

Therefore, the answer is A.) -7/10

Question 2:

We are going to subtract.

4 1/2 - 1 2/3

9/2 - 5/3

27/6 - 10/6

17/6 or 2 5/6

Note that we are still BELOW sea level so the number will be negative.

Therefore, the answer is C.) -2 5/6

Question 3:

We are going to subtract.

2 2/3 - 1 1/5

8/3 - 6/5

40/15 - 18/15

22/15 or 1 7/15

Therefore, the answer is B.) 1 7/15

Best of Luck!
