Instead of distributing 2, we can actually divide both sides by 2:
x - 1 = 2x - 11
Isolate x:
x = 10
Answer:
450,000
Step-by-step explanation:
899,765 to the nearest hundreds of thousands is 900,000 and the mid point of that should be 450,000 if I'm right
The height of each paper cup to the nearest whole number is 15cm
<h3>The volume of a cylinder and cone</h3>
The formula for calculating the volume of a cylinder is expressed as:
V = πr²h
r is the radius
h is the height
Given that h = 9cm and r = 3.8cm
V = 3.14 * (3.8)² * 9
V = 408cm³
For the cone
V = 1/3πr²h
408 = 1/3 (3.14 * (5.1)² * h)
1224 = 81.6714h
h = 1224/81.6714
h= 15cm
Hence the height of each paper cup to the nearest whole number is 15cm

The correct answer, rounded to the nearest km², is 2694.
Explanation:
This can be represented using an exponential equation of the form
y = a(1+r)ˣ, where y is the total amount, a is the initial population, r is the rate of increase or decrease written as a decimal number, and x is the amount of time.
In our problem, a = 4200, r = -8.5% = -8.5/100 = -0.085, and x is 5:
y = 4200(1+-0.085)⁵ = 4200(0.915)⁵ = 2693.73 ≈ 2694.
Answer:
-13,1
Step-by-step explanation:
f(x)= (x+6)^2-49
When we find the zero's we set f(x) =0
0= (x+6)^2-49
Add 49 to each side
49= (x+6)^2-49+49
49= (x+6)^2
Take the square root of each side
±sqrt(49) = sqrt((x+6)^2)
±7 = (x+6)
Subtract 6 from each side
±7-6 = (x+6-6)
±7-6 = x
7-6 =x -7-6 =x
1=x -13=x
