not so sure though but I think thats the answer
Answer:
D) 0.0004
Step-by-step explanation:
(0.02)^2=0.02*0.02=0.0004
3d + 4 = 2 + 3d - 1/2
3d + 4 = 1 1/2 + 3d |subtract 3d from both sides
4 = 1 1/2 FALSE
Answer: No solution ( x ∈ ∅ )
Answer:
156
312 and
39
Step-by-step explanation:
Let Allen be A , Jane be J and Bob be B
Allen has 4 times as Bob
So
A = 4B
Jane has twice as Allen
So
J = 2A
Together, Allen and Jane has 468 cards
A + J = 468
Substitute 2A for J in the third equation.
We have
A + J = 468
A + 2A = 468
3A = 468
Divide both sides by 3
3A/3 = 468/3
A = 156
Recall
A = 4B
Therefore
156 = 4B
Divide both sides by 4
156/4 = 4B/4
39 = B
B = 39
Also,
J = 2A
J =2 x 156
J = 312
Allen has 156 cards
Jane has 312 cards and
Bob has 39 cards
