Answer:
$5,024
Step-by-step explanation:
Answer:
A)
– 6x – 2x = 16
-8x = 16
x = 16/-8 = -2
B)
3(3x – 6) = 18
9x - 18 = 18
9x = 18 + 18 = 36
x = 36/9 = 4
C) ASSUMING YOU MADE AN ERROR BY WRITING 0 INSTEAD OF (
5(2x + 3) =-4(-5 – 2x)
10x + 15 = 20 + 8x
10x - 8x = 20 - 15
2x = 5
x = 5/2
12x =
Answer:
Answer. c
Step-by-step explanation:
Let 'x' denote the length of the base and let 'y' denote the length of the legs.
We know that isosceles triangles have one base and two legs that are the same length. So, the perimeter is:
x+y+y
= x+2y = 50
The problem tells us that the base is half as long as a leg, so that means:
y=2x
We can use the method of substitution here. Let's substitute the 2nd given equation into the first one. The work follows:
x+2y=50
x+2(2x)=50
x+4x=50
5x=50
x=50/5
x=10
To work out what the length of our legs are, we can use our found 'x' value to solve either of our previously established equations. Let's use the second one:
y=2x
y=2(10)
y=20
Just to confirm our answer is correct, let's verify it with our first equation.
x+y+y=50
10+20+20=50
50=50
Our answer is consistent, so the base has length 10, and each leg has length 20.
Answer:
The area of the circle is 113.0 ft²
Step-by-step explanation:
To solve this problem we need to use the area formula of a circle:
a = area
r = radius = 6ft
π = 3.14
a = π * r²
we replace with the known values
a = π * (6ft)²
a = π * 36ft²
a = 113.04ft²
The area of the circle is 113.04ft²
round to the nearest tenth
a = 113.04ft² = 113.0 ft²
