The product will be 12 :)
one slice of pizza is $3.75
Step-by-step explanation:
first write out 2 simultaneous equations from thr given information.
fries=f and pizza=p
4p+2f=21
2p+3f=16.5
and solve from there through either the substitution method or elimination. hope this helps
Solution :-
- 0.5 x - 5 < - 1.5
=> -0.5x < 3.5
[ multiplying inequality by ( - ) -ve sign changes the inequality ]
=> 0.5x > - 3.5
=> x > -7
Hence , -5 is the possible solution for the inequality because x is greater than -7 !
So , Lena is correct !!
