Question

-t/8=-9
A. t= -72
B. t = 1.125
C. t = 72
D. t = -17

Answer 1

i think its A

Answer 2

-t
-- = -9
8

Now just multiply: 8*-9 = -72

You're correct.

Answer 3

yes:) !

Answer 4

-5a=5/9

Answer 5

A.1/9 B. -1/9 C.25/9

Answer 6

D. X=-9

Answer 7

5 5 - 5 -25
-5a = --- = a = --- x --- ...:::... a = ----
9 9 1 9

Answer 8

OKAY SO just multiply

Answer 9

Answer 13

5
---
6x^5
----
9

Is that correct?

Answer 14

5/6d=2/3

Answer 15

Answers are : 1. d=4/5
2.d=5/9
3.d=3/2
4.d=7/9

Answer 16

i mean a.b.c.d

Answer 17

5 2
--d = -- = (Reverse by multiplying be reciprocal.)
6 3


The answer is d

Answer 18

thank you i would of never figured that out i would stuck on that ? for ever

Answer 19

Would you like me to tell you how I came to the answer?

Answer 20

yes please

Answer 21

5 2
--d = -- = (Reverse by multiplying be reciprocal.)
6 3

The reciprocal of a fraction is just that fraction turned upsidedown. I know fractions can look nasty in equations, but all you have to do to get rid of them is just multiply that fraction by itself.

5
So in order to get rid of --, we need to multiply the fraction buy its reciprocal.

5 6
Algebraically shown, the reciprocal of -- is --, now when you multiply those two they cancel
6 5

Back to the equation,

5 2 6 5
--d = -- ===> -- * --d (We multiplied by its reciprocal canceling the terms.)
6 3 5 6

Now we have isolated, 'd', on one side, all we need to do is multiply the other side by the reciprocal of 5
--
6

So we have, (Multiply straight across.)
2 6 12
d = -- * -- === --- = 0.75 = 4/5
3 5 15
