We can use a rule of three simple, direct proportion to solve this problem.
15 pounds correspond to $1.80, then the question is to find the price of one pound, the called unit rate. We state the rule of three:
15 pound ----> $1.80
1 pound -----> x
x = (1)(1.80)/15
x = 0.12
Therefore, each pound costs $0.12 that is the unit rate in pounds
The mathematical sentance would be, 740 - 14 = 726, hope this helps.:D
kkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkk
8z-22=3(3z+11)-z
9z-22=9z+33
-22=33
or
0=55
either way no solution
<span>11(23-x)
= 11(23) - 11x
= 253 - 11x</span>
