Answer:
Since Rectagle area is found by Length * Width, 20/8 would give the width of 2.5cm, if the length was increased by 2cm, and the area by 4cm, you would now do 24/10 to get the width which is 2.4, 5 percent of 2.5 is found by multiplying 2.5 by 0.05 which is 0.125, and 2.4 is only .1 less from 2.5 so yes noah is indeed correct, for that the width is decreased by less than 5%
Step-by-step explanation:
Answer:
the answer is 12
Step-by-step explanation:
Answer:
x 2 y -4
Step-by-step explanation:
13x = -54 -20y give it is A
-10x = 60 + 20y give it is B
A + B the sum of the left side of equation is equal to the sum of the right side of equation
13 + (-10x) = -54 -20y + 60 + 20y
3x = 60-54
3x = 6
x=2
so put the x value in A or B equation you can receive y value (B is easier)
y = -4
