The measurement is 9 cm. 144/16 would equal 9. and width times length is area, so to make sure you can do 9x16, which would equal 144

Help please! 12 POINTS!

Verizon [17]

Answer:

<h2>C & D are both, and only correct.</h2>

Step-by-step explanation:

a.)

5x + 10 = 12

x = 2/5 NOT 5/2, so this is in fact INCORRECT.

b.)

3x + 10 = 8

x = - 2/3 NOT 2/3, This too is INCORRECT.

c.)

9x + 15 = 36

x = 7/3. This is CORRECT!

d.)

8x + 12 = 24

x = 3/2. This is CORRECT!

Y=3/4X-5 POINT SLOPE FORM

lesantik [10]

Answer:

y + 5 = (3/4)x

Step-by-step explanation:

You want to rewrite Y=3/4X-5 in POINT SLOPE FORM?

Point-slope form looks like y-k = m(x-h), where (h,k) is a point on the line and m is the slope of the line.

Starting with Y=3/4X- 5, identify the slope and one point on the line. The slope is (3/4) (please surround fractions like this inside parentheses) and the y-intercept is (0, -5). We will let h=0 and k= -5.

Thus, we have a point on the line and we have the slope of the line.

We can now write the point-slope form:

y - (-5) = (3/4)(x - 0), or y + 5 = (3/4)x. This is the desired equation in point-slope form.

There are 25 balls. The chance of getting one of the ten red balls is 10/25. 10 divided by 25 is .2, which in percent form is 20%. I hope this helped!
