What is the actual area, in square meters, of this field?

lisov135 [29]

Answer:

70 m^2

Step-by-step explanation:

The key shows that each square side on the grid measures 2 m. The base of the triangle measures 7 grid square sides, so it measures 14 m. The height of the triangle measures 5 grid square sides, so it measures 10 m.

area of triangle = bh/2

area = (14 m)(10 m)/2

area = 140 m^2/2

area = 70 m^2

Solve the system of linear equations by substitution. y=2x+5 and y=3x-1

Doss [256]

Plug in the second equation into the first equation for y.
$y = 2x + 5 \\ y = 3x - 1 \\ 3x - 1 = 2x + 5$
Now put the variable on one side and constants on the other
$3x - 1 + 1 - 2x = 2x - 2x + 5 + 1 \\ x = 6$
Now plug that back into one of the original equations
$y = 2x + 5 \\ y = 2(6) + 5 \\ y = 12 + 5 \\ y = 17$
So now you know
$x = 6 \\ y = 17$
Its always a good idea to check
$17 = 2(6) + 5 \\ 17 = 17 \\ 17 = 3(6) - 1 \\ 17 = 17$

Answer:

y = 6

Step-by-step explanation:

3 y - x = 9

y = (2 x)/3

Substitute y = (2 x)/3 into the first equation:

{x = 9

y = (2 x)/3

Substitute x = 9 into the second equation:

Answer:

x = 9

y = 6
