Answer:
A centimeter is 1/100th of a meter. It would take the length of 100 cm to equal the length of a single meter. A centimeter is equivalent to 0.39 inches. ... A meter is equal to 3.28 feet, 1.09 yards or 0.00062 miles.
Step-by-step explanation:
Solve:
<span>-X - Y - Z =-8
- 4X +4Y +5Z=7
2X + 2Z =4 is the same as x + z = 2. Thus, z = 2 - x.
Subst. 2 - x for z in the 1st and second equations.
</span>-X - Y - Z =-8 becomes -x - y - (2 -x) = -8
- 4X +4Y +5Z=7 becomes -4x + 4y + 5(2-x) = 7
Now we have 2 equations in only 2 unknowns. Let's simplify them!
-x - y - 2 + x = -8 which becomes -y = -6, or y = 6
-4x + 4y + 10 - 5x = 7 which becomes -9x + 4y = 7 - 10 = -3
Now substitute 6 for y in this last equation: -9x + 4(6) = -3, or
-9x + 24 = -3, or
-9x = - 27 => x = 3
Then x = 3, y = 6 and z = 2 - x, or z = 2-3, or z = -1.
The solution is (3, 6, -1). Check it!!
Y = k/x
5 = k/8
k = 5 x 8 = 40
Therefore,
y = 40/14 = 2.86
The equation to find the lateral area of a cylinder is 2 pi r h
Plug it in

Answer:
£ 30
Step-by-step explanation:
Ratio = 3 : 5
Mo's share = 3x
Beth's share = 5x
Total amount = £ 48
3x + 5x = 48
8x = 48
{Divide both side by 8}
x = 48/8
x = £ 6
Beth's share = 5x
= 5*6
= £ 30
