Answer:
Since it does not plug in to the second linear equation, the ordered pair is not a solution of the linear system.
Step-by-step explanation:
(-1,3); y = -7x -4 y = 8x + 5 3 =7 - 4 3 =/ - 8 + 5
Answer:
2(b+1+b)= 18
Step-by-step explanation:
Perimeter of a rectangle= 2(l+b)
18 feet= 2(l+b)
length: l, breadth: b
Because the length of the sandbox is 1 foot longer, it will be:
b+1 = l
Substitute l with b+1
2(b+1+b)= 18
Answer:
B
the measure of angle A: 18.6°
measure of angle B: 55.8°
measure of angle C: 105.6°
Step-by-step explanation:
6x - 6 + 3x + x = 180
10x - 6 = 180
10x (- 6 + 6) = 180 + 6
10x = 186
10x/10 = 186/10
x = 18.6
18.6 + 3(18.6) + [6(18.6) - 6] = 180
18.6 + 55.8 + 105.6 = 180
180 = 180
Just scan it, there’s an answer for it already I’m pretty sure
