Answer:
4 ft.
Step-by-step explanation:
We can consider the orignial square's sides to be x, so area of the original figure: 
The new rectangle's sides will be x and x+8, so the area of the new figure will be x^2+8x.
We know that the new area is 3 times the old one. So our equation will be:
x^2+8x=3x^2
our answer will be x=4.
Therfore, the length of the side of the old flower bed is 4 ft.
Answer:
About 1 hour and 16 minutes
Step-by-step explanation:
From the problem, we can think that the distance between them is narrowing 11 km/hr (8 + 3). Therefore, after one hour the herd and the ranch hand are 3 km apart. We can then use 11 km/hr from earlier, and get the answer of 1 hour and 3/11 of an hour, which is about 1 hour and 16 minutes.
This is how you can solve it;
5 = 15y
5 ÷ 15 = y (did the inverse operation of the variable)
0.33 = y or y = 0.33 (rounded to the nearest hundredth)
To check your answer just substitute the value of y in the equation;
5 = 15y
5 = 15(0.33)
5 = 5
so your answer is correct! :D Hope that helps!<span />
1. Add all the sides 33 inches left and right and 75 inches. up and down.
Perimeter= 216
2. If 2/3 pounds is needed for 1 cheese cake and you have 2 pounds its not enough so 2 minus 2/3 will give you a mixed fraction : 1 over 1/3 or a decimal : 1.3
Idk if they want you to divide but if they do then your answer is 1/3
Answer:
The found values are:
A = 1/3
B = -8/3
Step-by-step explanation:
We know that general equation is given by:
y = mx + c
where m is the slope and c is a constant.
x + 3y = -5
y = -(1/3)x - 1/3(5)
Slop of the equation is -(1/3). As parallel line have same slope substitute it in the first equation:
Ax + By = 3
By = -Ax - 3
By = (1/3)x - 3
Hence, A = 1/3
Substitute point (-7,2) into the equation:
B(2) = (1/3)(-7) -3
B(2) = -7/3 - 3
B(2) = -16/3
B = -16/6
B = -8/3
