Answer:
the awnser is 9
Step-by-step explanation:
because if it takes 7 h to make 21 k of dough that means every hour he makes 3 k of dough and to get to 27 we need to do this : 3x2=6 , and 21 +6= 27 and since every hour he makes 3 k of dough and we multiplyed 3x2 that means we have to add 7 +2=9 that is how we solve:)
Answer:
4x+3y=71.5
3x+y=38
Step-by-step explanation:
If we pretend that x represents shirts and y represents shorts than they represent these equations perfectly. First of all we have to see that we are not subtracting anything so there really isn't any reason to use negative symbols. Anyway looking at these equations if we get 4 shirts (x) and one (shorts)(y) then the total should be $38. Same for Justine's equation 4 shirts (x) and 3 shorts(y) the total should match her $71.5
