27 1/5 over 4/5 as a unit rate

REY [17]

Answer:

$\frac{34}{1}$ or $34$

Step-by-step explanation:

we know that

To find the unit rate divide 27 1/5 by 4/5

but first

Convert mixed number to an improper fraction

$27\frac{1}{5}=27+\frac{1}{5}=\frac{27*5+1}{5} =\frac{136}{5}$

$\frac{136}{5}:\frac{4}{5}=\frac{136}{4}=\frac{34}{1}$

Answer:

x = 2

y = -3

z = 4

( 2 , -3, 4 )

Step-by-step explanation:

x + y + z = 3 ---- i

x – y =5 ---- ii

y - z = -7 ---- iii

ii + iii

x - z = -2 ---- iv

i + ii

2x + z = 8 --- v

iv + v

3x = 6

x = 2

x=2 substitute for v

z = 4

x =2 substitute for ii

y = -3
