Substitution method of y=x+5 and 5x+y=3

To solve by substitution, you need to fill in the value for either x or y. Since y = x + 5, you already have the y value. It's x + 5. Now you need to find x before you can go any further. So let's take 5x + y = 3 and fill x + 5 in for y. 5x + y = 5 5x + x + 5 = 3 Now solve for x. 5x + x + 5 = 3 6x + 5 = 3 6x = 3 - 5 6x = -2 x = -2/6 or -0.33 Now solve x + 5 for y. y = x + 5 y = -0.33 + 5 y = 4.67 So x = -0.33 and y = 4.67

64,328 to the ten thousands place
Flauer [41]
If you are looking to round, then you simply either round up or round down due to the term before the place you want to round (in this case, the thousands place). when you round in this case, you would round down because 4 is less than 5 (the middle point between 0 and 10) in which case would give us 60,000

What is the distance between the points (2,-3) and (-6,4) on the coordinate plane?
gulaghasi [49]

\bf ~~~~~~~~~~~~\textit{distance between 2 points} \\\\ (\stackrel{x_1}{2}~,~\stackrel{y_1}{-3})\qquad (\stackrel{x_2}{-6}~,~\stackrel{y_2}{4})\qquad \qquad d = \sqrt{( x_2- x_1)^2 + ( y_2- y_1)^2} \\\\\\ d=\sqrt{[-6-2]^2+[4-(-3)]^2}\implies d=\sqrt{(-6-2)^2+(4+3)^2} \\\\\\ d=\sqrt{64+49}\implies d=\sqrt{113}\implies d\approx 10.63

So he bought 8.5 pounds, and you have to find out how many ounces he bought. That would mean that you have to convert pounds to ounces. There are 16 ounces in 1 pound. In 8.5 pounds, there are 136 ounces.
