The answer is 7 because it’s 7
Answer:
x = -7
Step-by-step explanation:
4 - 2(x - 3) = 24
Distribute
4 -2x +6 = 24
Combine like terms
10 -2x = 24
Subtract 10 from each side
10-2x-10 = 24-10
-2x = 14
Divide by -2
-2x/-2 = 14/-2
x = -7
Answer:
84.85cm
Step-by-step explanation:
Let the sides of the square be x
The perimeter of the square = 4x
Get x using the pythagoras theorem
x^2 + x^2 = 30^2
2x^2 = 900
x^2 = 450
x = 21.21cm
Perimeter of the plate = 4(21.21)
Perimeter of the plate = 84.85cm
Part A you can figure out that the car is traveling at 50 miles an hour because after every hour the distance decreases by 50
b the average change is 100 miles for every 2 hours, which can be simplified back to 50mph which represents the speed of the car
part C {y=-50x+900| (0,900),...(18,0)
Fv=500×(1+0.04×3)+250×(1+0.04×2)+
250×(1+0.04×1)=560+270+260=1,090
