Answer:
The value of x is 3.
Step-by-step explanation:
Matthew earned 7500 of 15000, which is exactly half the total amount, meaning that the fraction corresponding to his earnings is 1/2.
Rate of 5:2:x, with number 5 corresponding to Matthew, mean that his fraction of the earnings, in function of x is given by:

Both fractions are equal, so:

Applying cross multiplication:



The value of x is 3.
It is C a pyramid! They ask for shape but no measurements

Hello :
<span>1/5x-2=1/3x+8
let ; y = </span><span>1/5x-2 ..... (1)
y=1/3x+8 .....(2)
by (1) : 1/5 x =y+2
x = 5y +10....(*)
by (2) : 1/3x = y-8
x = 3y-24 ....(**)
(*) :5y-x = -10
(**) : 3y-x =24 ......( last answer )
