Answer:

43/100

Step-by-step explanation:

First, make both of the denominators into 100.

Then, 3/10 would be 30/100.

Finally, you can add them to get 43/100.

43/100
Make both denominators into 100 so that means 3/10 would be 30/100 then you add both so 30/100+ 13/100 only adding the numerators so it will equal 43/100

You have two jobs. You earn $8 for each hour x that you work as a restaurant host and $6 for each hour y that you work as a hair
Yanka [14]
SOLUTION:

a ) Write an equation in standard form that models your earnings.

8x + 6y = $114


b ) You worked 10 hours as a hair washer. How many hours did you work as a host?


8x + 6y = $114

8x + 6 ( 10 ) = 114

8x + 60 = 114

8x = 114 - 60

8x = 54

x = 54 / 8

x = 27 / 4 hours

x = 6.75 hours

x = 6 hours and 45 minutes

What's the next fraction after 45/60
Darya [45]
You could say 46/60 (both of these fractions can be reduced), but we can find a fraction between 45/60 and 46/60, namely 91/120.  And we can find another between 45/60 and 91/120, and so on ad infinitum.

To answer your question, there is no next fraction.  Infinitely many may be found between any two.

(4x-y=-15)<br>(3x-2y=-10)<br>​
Andreyy89

Answer:

<h2>x = -4 and y = -1 → (-4, -1)</h2>

Step-by-step explanation:

\left\{\begin{array}{ccc}4x-y=-15&\text{multiply both sides by (-2)}\\3x-2y=-10\end{array}\right\\\underline{+\left\{\begin{array}{ccc}-8x+2y=30\\3x-2y=-10\end{array}\right}\qquad\text{add both sides of the equations}\\.\qquad\qquad-5x=20\qquad\text{divide both sides by (-5)}\\.\qquad\qquad\boxed{x=-4}\\\\\\\text{Put the value of x to the first equation.}\\\\4(-4)-y=-15\\-16-y=-15\qquad\text{add 16 to both sides}\\-y=1\qquad\text{change the signs}\\\boxed{y=-1}
