Which choice is the most efficient first step to solve this set of equations?

Mathematics
1 answer:
Sloan [31]3 years ago
4 0

Answer:

Substitution is the most efficient.

Step-by-step explanation:

Because the equation y = 2x + 4  already equates to y, one can easily substitute its expression 2x+4 into 3x + 4(y) = 17 where y is.

3x + 4(y) = 17

3x + 4(2x + 4 ) = 17

Paraphin [41]

Answer:

A four mile ride would cost $10

Step-by-step explanation:

Let T be the total ride cost

Let M be the amount of miles driven

T = 1.75M + 3

You can now sub in any distance in miles into the equation, but for this instance lets sub in 4 miles

T = 1.75*(4) + 3

T = 7 + 3

T = 10

Therefore, a four mile ride would cost 10 dollars

The perimeter of a rectangle is 38 inches. If the length of the rectangle is 14 inches, which equation could be used to find the
Solnce55 [7]
Perimeter, P = 2*(L + W)

Length, L = 14, Width = x

 P = 2*(L + W)

38 = 2*(14 + x).

2*(14 + x) = 38,  is the equation used to find x.

Let's go ahead and solve for x, though the question did not ask us to solve it. 

 14 + x = 38/2

  14 + x = 19

       x = 19 - 14

        x = 5

Width is 5 inches.
