2 x
----- = ------
3 15
cross multiply
(3)(x) = (15)(2)
3x = 30
x = 30/3
x = 10
so 2/3 = 10/15.......notice how these are equivalent fractions....that is because proportions are nothing but equivalent fractions
Y= 2x-3 i think, but i may be wrong
Answer:
Around 13 lunches
Step-by-step explanation:
If you divide 100 and 7.50, you get 13.33 and if you round it, it equals 13.
The given expression is : (4x – 7.2) + (-5.3x-8)
Simplify :
Open the brackets :
(4x – 7.2) + (-5.3x-8) = 4x - 7.2 - 5.3x - 8
Arrange the variable and constant terms together :
(4x – 7.2) + (-5.3x-8) = 4x - 5.3x - 8 - 7.2
Solve the variable and constant terms together :
(4x – 7.2) + (-5.3x-8) = - 1.3x - 15.2
Since, the variable and constant term can not solve together so the above equation is the simplest form:
(4x – 7.2) + (-5.3x-8) = - 1.3x - 15.2
Answer : (4x – 7.2) + (-5.3x-8) = - 1.3x - 15.2
