6C + 47M=893.50 25C + 22M=527.86

Mathematics

Olenka [21]3 years ago

Answer:

C = 4.94   M = 18.38

Step-by-step explanation:

the easiest way is to graph both equaitons and see where they intersect,

see the image

or solve by substitution

6C + 47M=893.50           C = (893.50 - 47M)/6

25C + 22M=527.86

25((893.50 - 47M)/6)  + 22M = 527.86

25/6 [(893.50) - 47M] + 22M = 527.86

25/6 [ - 47M] + 22M = 527.86 - 25/6 [(893.50)

22M - 25(47M)/6  = -3195.06

22M - 195.83M  = -3195.06

      -173.83M   =   -3195.06

                 M  =  18.38

C = (893.50 - 47(18.38)/6

C = 4.94

The explicit formula for a sequence is
Alexandra [31]

Answer:

28

Step-by-step explanation:

Let n = 21, and evaluate the expression.

a_n = -2 + \dfrac{3}{2}(n - 1)

a_{21} = -2 + \dfrac{3}{2}(21 - 1)

a_{21} = -2 + \dfrac{3}{2}(20)

a_{21} = -2 + \dfrac{3}{1}(10)

a_{21} = -2 + 30

a_{21} = 28

Select the statement that correctly describes the expression below
Kitty [74]

Answer:

B

Step-by-step explanation:

The equation is (2x+5)^2.

It can't be A because 2 is the multiplier for only x.

It can't be C because the square is outside of the equation.

It can't be D because again, the square is outside of the equation.

So the only thing left is B.

Hope this helped!

Solve for b: y = mx + b<br> +mx + mx<br> y + mx = b
Kruka [31]

Answer:

Here's what I got. First of all, did you meant y=mx+b+mx+mxy+mx=b, because that's undefined, or did you meant y=mx+b+mx+mx, which is b=−3mx+y.
