Answer: w =40m

dependent variable = w

independent variable = m.

Step-by-step explanation:

Hi, to answer this question we have to write an equation:

The number of words typed (w) will be equal to the product of the number of words typed per minute (40) and the number of minutes (m)

w =40m

The dependent variable is w , and the independent variable is m.

Because the output value of w depends of the input value of m.

Answer:

21.6 or 22

Step-by-step explanation:

Triangles have same angles. This means that they are proportion.

50/27 = 40/x

when you cross multiply to solve x, 50x = 1080

so x = 21.6

If you have to nearest whole number, it will be 22

Eliminate 3x+2y=4<br> 8x-3y=-6

laila [671]

Steps:
1. Multiply the first line by 3 and the second by 2
3(3x + 2y= 4)
2(8x -3y=-6)
2. New lines are
9x + 6y= 12
16x + -6y=-12
3. Now add/subtract them
25x + 0= 0
25x=0
4. Divide by 25
X=0

5. To find y, substitute the 0 in the x in one of the equations
9x + 6y= 12
9(0) + 6y= 12
6y= 12
6. Divide by 6, your Y=2
7. X=0, Y=2
