Answer:
v = 9
Step-by-step explanation:
Use the method of cross- multiplying
= 
⇒ ad = bc
8v = 12 × 6
8v = 72 ( divide both sides by 8 )
v = 9
500 at 40 each = £20000
To make a profit he needs to make more than £20000
20 broke so he sold 500-20 = 480 at 45 each.
480 x 45 = 21600
Profit = 21600 -20000 = 1600
His profit was £1,600
Answer:
Declare<em> h.</em> We can declare it as any number, so let's say 2.
h - 13 = 11 ↓
because h = 2.
To do this let's put 129 where X is, like this: -12(129)+14(129)-6(129)
Now we multiply -12 by 129, which is equal to -1548.
Now we multiply 14 by 129, which is equal to 1806.
Now we multiply -6 by 129, which is equal to -774.
Now, let's put these numbers into an equation, like this: -1548+1806-(-774).
The answer to this equation is 1032.
I hope this helps.
