$find\ "x"\\\\y=-\frac{2}{3}x+4\ \ \ \ |subtract\ 4\ from\ both\ sides\\\\y-4=-\frac{2}{3}x\ \ \ \ |multiply\ both\ sides\ by\ 3\\\\3y-12=-2x\to-2x=3y-12\ \ \ |divide\ both\ sides\ by\ (-2)\\\\x=\frac{3y}{-2}-\frac{12}{-2}\\\\x=-\frac{3}{2}y+6\\\\Your\ answer:\boxed{y=-\frac{3}{2}x+6}$

A family has annual loan payments equal to 30% of their annual income. During the year, their loan payments total $15,680. What

soldier1979 [14.2K]

First, set up a ratio: $\frac{30}{100} = \frac{15,680}{x}$
The first fraction is the percentage (30% and $\frac{30}{100}$ are the same thing) and the second is the loan payment (which is equal to the 30 in the first fraction) over their annual income ( $x$ ).
First you divide $15,680 by 30, then multiply that quantity by 100. The value calculated then replaces $x$ in your second fraction: $\frac{30}{100} = \frac{15,680}{52,266.67}$

A car drives for 1 hour 55 minutes with a constant speed of 36 km/h and then for another 1 hour 50 minutes with a constant speed

stich3 [128]

----------------------------------------
Convert hours to minutes
----------------------------------------
1 hour 55 mins = 60 + 55 = 115 mins
1 hour 50 mins = 60 + 50 = 110 mins

_____________________________________________________

----------------------------------------
Speed = 36/h
----------------------------------------
1 hour = 36 km

----------------------------------------
Rewrite 1 hour as 60 mins
----------------------------------------
60 mins = 36 km

----------------------------------------
Find 1 min
----------------------------------------
1 min = 36 ÷ 60
1 min = 0.6 km

----------------------------------------
Find 115 mins
----------------------------------------
1 min = 0.6 km
115 min = 0.6 x 115
115 min = 69km

_____________________________________________________

----------------------------------------
Speed = 72km/h
----------------------------------------
1 hour = 72 km

----------------------------------------
Write 1 hour as 60 mins
----------------------------------------
60 mins = 72 km

----------------------------------------
Find 1 min
----------------------------------------
1 min = 72 ÷ 60
1 min = 1.2 km

----------------------------------------
Find 110 min
----------------------------------------
1 min = 1.2 km
110 min = 1.2 x 110
110 min = 132 km

_____________________________________________________

----------------------------------------
Total Distance traveled:
----------------------------------------
69km + 132km = 201km

----------------------------------------
Answer: 201 km

Show how to get answer to...<br> 3/4+9/6 =

svet-max [94.6K]

The answer for your question is 2.25 (decimal), or 2 1/4.

I got this answer by changing both 3/4 to 9/6, which 3/4 = 0.75, and 9/6 = 1.50.

Now, you add both 0.75 and 1.50 together, which gives you 2.25, which is the answer that I got.

Hope this helped!
