Answer:
3 ft times<em> x </em>ft
Step-by-step explanation:
You don't know what the x is so you can keep it as a x.You are going to multiply it so it is 3 ft times<em> x </em>ft
4x - 5y = -12
-x + 5y = 18
Add the equations together:
4x + -x = 3x
-5y + 5y = 0
-12 + 18 = 6
So now you have:
3x = 6
Divide both sides by 3:
X = 2
Now you have the value of x, replace x with 2 in one of the equations and solve for y:
4(2) -5y = -12
8 -5y = -12
Subtract 8 from both sides:
-5y = -20
Divide both sides by -5:
Y = 4
The solution is x = 2 and y = 4 which is written as (2,4)
Answer: 177.4999849 , or 56.5pi
Step-by-step explanation:
You simply divide the diameter by 2 to get the radius (28.25) and then plug into the circumference equation, 2*pi*r = Circumfrence.
Answer: 7
Step-by-step explanation:
You can either remove brackets and just do a little addition and subtraction.
So the answer is 7.
Or just finish things inside the brackets first.
So the answer is 7.
Multiply 7 x 12 which is 84, 8x2 is 16, 16 divded by 3 is 5, so 5 minutes
