Add 1/2 liter,3/4 liter and 7/8 liter
LUCKY_DIMON [66]
First, find a lowest common denominator. The lcd in this equation os 8 so your new fractions would be 4/8, 6/8, and 7/8. You add the numerators (top numbers), which equals 17/8. Then you simplify to 2 1/8 liters.

PLEASE HELPPPPPP!!!!!!Solve this system of linear equations separate the x-and y-values with a comma
GenaCL600 [577]

Answer:

x=-6,\\y=6

Step-by-step explanation:

Rewrite the system of equations as:

\begin{cases}-13x+2y=90\\-6x+2y=48\end{cases}

Subtract the second equation from the first to isolate x:

-13x+2y-(-6x+2y)=42,\\-7x=42, \\\fbox{$x=-6$}

Plug in x=-6 into any of the equations above and solve for y:

-6(-6)+2y=48,\\2y=12,\\\fbox{$y=6$}

Verify that the solution pair (-6, 6) works \checkmark

Therefore, the solution to this system of equations is:

x=-6,\\y=6

Josie had some money in her bank account. She went shopping and spent $493.98. After shopping she still had %185. How much money
solong [7]

Answer:

$678.98

Step-by-step explanation:

Let the amount she had before she started spending be T. If she went shopping and spent $493.98 then the amount she would have is

= T - 493.98

Given that she has $185 left then

T - 493.98 = 185

Add 493.98  to both sides

T - 493.98 + 493.98 = 185 + 493.98

T = $678.98

She must have had $678.98 in her bank account to begin?
