6(1—a) =3(a—b)+1 4(b—2) =3a Consider the system of equations above. If (a, b) is the solution to the system, then what is the
Jet001 [13]
6-6a=3a-3b+1,    9a-3b=5
<span>4b - 8 =3a,           3a-4b=-8
</span> 
9a-3b=5
(3a-4b=-8 )*(-3 )

 
9a    -3b=    5
-9a+12b=+24
adding both equations
9b=29, b=29/9

3a=4b-8=4*29/9 -8=(4*29-8*9)/9 = 44/9
a=44/27
a-b=44/27 - 29/9=44/27 - 29*3/27=-43/27
this is a correct answer, unfortunately they do not have this choice, probably they made mistake somewhere. I even check the solution of equations by substitution values of a and b into equations

vredina [299]

This question is not correctly written

Correct question

Noah drank 4/5 liter of water Monday before going jogging. He drank 2/3 liter of water after his jog. How much water did Noah drink altogether? Write your answer as a mixed number.

Answer:

1\frac{7}{15}

Step-by-step explanation:

Noah drank 4/5 liter of water Monday before going jogging. He drank 2/3 liter of water after his jog.

To find the total liters of water he drank, we should add up the liter of water  he drank on Monday before going jogging and  liter of water after his jog.

4/5 + 2/3

Find the Lowest Common Multiple for 5 and 3 , which is 15.

= [(4×3) + (2×5)] /15

= 12 + 10/ 15

= 22/15

As a mixed Fraction, the answer

= 1\frac{7}{15}
