Answer:
x=-6
y=-11
Step-by-step explanation:
x-y=-5
7x+3y=-75
x=5+y plug that in to the second equation
7(5+y)+3y=-75
35+7y+3y=-75
10y=-75-35
10y=-110
y=-11
plug y into first equation
x+11=5
x=5-11
x=-6
Answer:
It is answer B (125 / 360) * 42
Step-by-step explanation:
The length of the diagonal will be given by:
cos θ=adjacent/hypotenuse
θ=35°
hypotenuse=h
adjacent=80 inches=6.66667 ft
thus;
cos 35=6.66667/h
h=6.66667/cos35
h=8.1385 ft
diagonal=8.1385 ft
we conclude that the table will through the door diagonally.
-2 = KM, just simplify the equation.
