Solve for y<br> 2x + 5y > 3y + 10

vladimir1956 [14]

Answer:

y>5-x

Step-by-step explanation:

To solve this problem we need start by grouping terms in the same side of inequality.

Lets begging by grouping 'y' terms on the left side of inequality sign, to do this, subtract 3y to both sides:

2x+5y-3y>3y-3y+10

2x+2y>10

Now lets subtract 2x to both sides of inequality.

2x-2x+2y>10-2x

2y>10-2x

Now isolate variable x by dividing the inequaiity by 2.

y>5-x

That is the solution

against the wind a small plane flew 280 miles in 1 hour and 10 minutes. the return trip took only 50 minutes. What was the speed

Amanda [17]

1) 1hour 10minutes = $\frac{7}{6}$ hours,
50 minutes = $\frac{5}{6}$ hours

2) speed of plane against the wind = $\frac{280miles}{ \frac{7}{6} } = \frac{280*6}{7}=240miles /hours$

3) speed of plane on the the wind = $\frac{280miles}{ \frac{5}{6} } = \frac{280miles*6}{5}=336miles/hours$

4) (336-240):2=48miles/hours - speed of wind
5)336-48=288miles/hours - plane's speed <span>in still air

Answer: speed of wind is 48 miles/hours, speed of </span>plane in still air is 288 miles/hours

How do you solve for 3x=-8 - 2y

Nesterboy [21]

Answer:

y=(3/2)x+4

Step-by-step explanation:

Get y alone. 2y=3x+8 Divide the whole equation by 2, and that leaves you with y=(3/2)x+4
