Is (1, 2) a solution to the inequality 6x - y> 3?
Lostsunrise [7]

Answer:

<u><em>Yes.</em></u>

Step-by-step explanation:

<em>To find the answer we will put it into the equation, since</em><em><u> x = 1 and y = 2</u></em><em> we will write it like this, </em><u><em>6(1) - 2 > 3.</em></u><em>  Since </em><u><em>6 x 1 = 6</em></u><em>, we will now </em><u><em>subtract 6 from 2 which equals 4</em></u><em>.  Therefore, the equation is </em><u><em>correct because 4 is bigger than 3.</em></u>

What is 7x+5=5x+17
seropon [69]

Answer:

x=6

Step-by-step explanation:

When you have 7x+5=5x+17, you try to get the variables on one side and the constants on the other. Subtract 5x from the right and from the left: 2x+5=17. Next, subtract 5 from the left and from the right: 2x=12. The last step is to get rid of the coefficient of x and to do that divide it by the coefficient(in this case divide both sides by 2). After dividing 2x and 12 by 2 you get x=6.

Jen picked three fourth in half an hour if she keeps the same rate how many will she pick in 2 hours
Sunny_sXe [5.5K]

Alright, lets get started.

Jen picked three fourth in half an hour.

Half an hour means 30 minutes.

At the same rate, how many she can pick in 2 hours.

2 hours means 2 * 60 = 120 minutes

Now,

In 30minutes, Jen can pick = \frac{3}{4}

In 1 minute, Jen can pick = \frac{3}{4} *\frac{1}{30}

In 120 minutes, Jen can pick = \frac{3}{4} *\frac{1}{30} * 120 = 3

Hence Jen can pick complete 3 in 2 hours of time.

So the answer is 3 :   Answer

Hope it will help :)
