Explain how you can use mental math to compare 7 pounds to 120 ounces.

Eva8 [605]

One pound consists of 16oz, you have 120oz. If you divide 120 and 16 you get 7.5 lbs. so therefore you have more oz than lbs.

A triangle with side lengths of 5, 12, and

nikklg [1K]

Answer:

51.2

Step-by-step explanation:

$\frac{15}{5} = \frac{25}{x}$

15x = 120

x = 8

so now we know that 2 sides of the bigger triangle are 24 and 8

now

$\frac{8}{x} = \frac{5}{12}$

96 = 5x

x = 19.2

19.2 + 24 + 8

Graph the line with a slope of 2/3 that contains the point (−3,−5)

Anna007 [38]

Answer:

Step-by-step explanation:

So for the given information, it would be easiest to use slope-intercept form, which is y=mx + b, where m is the slope and b is the y-intercept.

We can plug in 2/3 for the slope, because we are given that.

y=2/3x + b.

To find the y-intercept, plug in the given point for x and y and solve for b.

-5 = 2/3 · (-3) + b

-5 = -2 + b

b = -3

So now we have the complete equation of the line.

Now to graphing.

We can put the y-intercept, (0, -3), and the given point, (-3, -5) on a graph.
