Step-by-step explanation:
these look easy you can probably just type it into a calculator, just show your work.
not sure where you got 20 from on the first problem it should be 9/12 I think, based on the examples at the top of the page.
1. 9/12
2. 16/22
3. 30/36
4. 28/44
5. 45/55
6. 50/60
The "/" indicates division btw and or fraction
then do the #x#x#x#x# thing you were doing
The value of z if x = 36 and y = 6 is 42
<h3>Direct and inverse variation</h3>
Suppose that y varies directly with x and inversely with z, hence the required expression will be:
y = kx/z
If y = 4 when x = 8 and z = 14 then;
4 = k(8)/14
8k = 56
k = 7
To find z when x = 36 and y = 6, we will have:
6 = 7(36)/z
1 = 7(6)/z
z = 42
Hence the value of z if x = 36 and y = 6 is 42

Answer:
y = 2
Step-by-step explanation:
x + 5y - 10 = 0
X = 4y - 8
since x is given as = 4y - 8 we can use this in first equation
replace x with 4y - 8
x + 5y - 10 = 0 ➡ 4y - 8 + 5y - 10 = 0 add like terms
9y - 18 = 0 add 18 to both sides of the equation
9y = 18 divide both sides by 9
y = 2
