Substitute with the value of n in the equation to get m as follows:
at n=1:
2m=-6(1)-5=-6-5=-11
m = -11/2
at n=2:
2m=-6(2)-5=-12-5=-17
m = -17/2
at n=3:
2m=-6(3)-5=-18-5=-23
m = -23/2

<h3>3 Answers:</h3>
  • A) The product of the area model is 3055
  • D) The missing number is 200
  • E) The model shows 47 x 65

=======================================================

Explanation:

The first number along the top is 40, and it multiplies with the second number along the side to get 40 x 5 = 200

You can think of it as 4 x 5 = 20, then you tack on an extra 0 to the '4' and to the '2' as well, so it keeps things balanced.

So this explains how choice D is one of the answers.

-------------------------

After 200 fills in that question mark, we'll have these four numbers inside the table: 2400, 420, 200, and 35

Those four values add up to: 2400+420+200+35 = 3055

This shows that choice A is one of the answers.

--------------------------

Finally, choice E is the third answer because along the top we have 40+7 = 47, and along the side we have 60+5 = 65

Put another way, the total top length is the sum of the two smaller pieces of 40 and 7, which explains how the total top length is 47 units long. A similar argument happens for the left side values as well.

We ultimately have a rectangle that is 47 units across in the horizontal direction, and 65 units tall in the vertical direction.

With your calculator, you should note that 47*65 = 3055 to help confirm everything lines up.

--------------------------

Extra info:

Choice B is false because this contradicts choice D.

Choice C is false because it contradicts choice E

The function v(r) 4/3 pie r to the 3rd = can be used to find the volume of air inside a basketball given its radius. What does V
umka21 [38]

Answer:

  the volume of the basketball when the radius is r

Step-by-step explanation:

V(r) is a function name V and argument list (r). Often the letter of the function name is a reminder of what the function computes. Here, V is chosen as the name because it computes Volume. The function uses r (for radius) as its independent variable. That is why r is listed in parentheses next to the function name.

So, V(r) represents a function that computes the volume of a sphere with radius r.

Write this decimal as a fraction. 0.45 repeating
sergij07 [2.7K]

Answer:

= 45/99 (since 45 is the repeating part of the decimal and it contains 2 digits). We can divide both the top and bottom parts by 9 to find that 0.454545… = 45/99 = 5/11.

Step-by-step explanation:

Hope this helps!

Use the digits 5,4 and 8 once each to write an odd number greater than seven hundred
natali 33 [55]
845 because 800 is greater than 700 and 845 is an odd number because it ends in 5 (which is an odd number).
