Answer:
The cost of the delivery is $120
Step-by-step explanation:
A * 4 = E........A = E / 4
B / 4 = E........B = 4E
C + 4 = E......C = E - 4
D - 4 = E.......D = E + 4
A + B + C + D = 100
(E/4) + (4E) + (E - 4) + (E + 4) = 100
E/4 + 6E = 100 ....multiply by 4
E + 24E = 400
25E = 400
E = 400/25
E = 16 <===
We know that
To find the LCM<span>,
we must find the prime factorization of each number
</span>15=3*5
8=2³
Now, we have to multiply the different<span> factors, and we only choose the ones which have the greatest exponent.
</span>LCM=3*5*2³-----> LCM=120
the answer is
LCM is 120
I think your answer would be 5%.
