Step-by-step explanation:
Yes they are equivalent. You get -3 when you try solving the actual equation.
Answer:
D. 19.5 Ft.
Step-by-step explanation:
Formula: B · H = A
Substitution: 3.25 · 2 = 6.5
6.5 · 3 ( 3 Windows ) = 19.5 Ft.
Well they are similar by ASA
30/25=1.2
20*1.2=24
24=4x-4
28=4x
7=x
Write as a system y= 2 x + 2.4x - 2y = 4
{y = 4
{2x + 2.4x - 2y = 4
Substitute the value of y into the equation
2x + 2.4x - 2 x 4 = 4
Solve the equation
x= 30/ 11
A possible solution is
(x, y) = (30/11, 4)
Check the solution
4 = 2 x 30/11+ 2.4 x 30/11 - 2 x 4 = 4
Simplify the expression
4 = 4 = 4
The ordered pair is a solution
(x, y) = ( 30/11, 4)
