Answer:
x = -3
Step-by-step explanation:
4x - 5 + 2(x - 3) = 12x + 7
4x - 5 + 2x - 6 = 12x + 7
6x - 11 = 12x +7
6x - 12x = 7 + 11
-6x = 18
x = -3
Let
x------> the <span>height of a cylinder
y------> the radius </span>of a cylinder
we know that
x=5y
[t<span>he lateral area of the cylinder]=[perimeter of the base]*height
</span>[perimeter of the base]=2*pi*r-------> 2*pi*y
[the lateral area of the cylinder]=[2*pi*y]*(5y)-----> 10*pi*y²
10*pi*y²=360*pi-----> y²=36--------> y=6 units
<span>
the answer is
</span><span>the length of the radius of the cylinder is 6 units</span><span>
</span>
Step-by-step explanation:
y=mx-c
m=gradient
L1: y=3x-2
gradient: 3
L2:
3y-9x+5=0
3y=9x-5
y=3x-5/3
Gradient:3
when gradients of 2 lines are equal, the lines are parallel

The numbers should be 2, 2, 5, 9 and 12.
<h3>What is mean, mode and median?</h3>
The arithmetic mean is found by adding the numbers and dividing the sum by the number of numbers in the list.
The median is the middle value in a list ordered from smallest to largest. The mode is the most frequently occurring value on the list.
Let us take numbers 2, 2, 5, 9 and 12.
mean = 30/5
mean= 6
range = 10.

Answer:
5
Step-by-step explanation:
(2x + y) - z
Let x=3 y=4 and z=5
2*3 +4 -5
Multiply and divide first
6 +4 -5
Then add and subtract
