L = lemon drops
J = jelly beans
L +J = 100
L=100-J
1.90L + 1.20J=1.48*100
1.90(100-j) +1.20J =148
190-1.90J+1.20J=148
190-0.7J=148
-0.7J=-42
J = 60
L=100-60 = 40
40 pounds of Lemon Drops are needed
Answer:basically if what they want you to prove is correct say it is correct and why is it correct
Step-by-step explanation:
Answer:
10.37
Step-by-step explanation:
find the area of the whole rectangle which is 30 then find the area of the circle which is 19.63 then subtract 30-19.63
V•w = (-7i +4j)•(-6i +5j) = (-7)×(-6) +4×5 = 42 +20
v•w = 62
