(7+21)=28
28(3-I)=
28•3 =84
28•I=28i
28/84=3,5
3,5=I
Answer:
B
Step-by-step explanation:
The given equations satisfy the given conditions. There are 2 equations and 2 unknowns, so a certain solution can be found.
This can be solved using substitution,
Substituting eqn 2 to eqn 1:
2(2y – 10) + 3y =1240
Simplifying,
y = 180
x = 350
Answer:
35%
Step-by-step explanation:
63/180=0.35
move the decimal over 2 spaces 35%
Answer:
Could be 12 or 16. Need more information
Step-by-step explanation:
then you figure out what you divide 56 by to get 4. which is 14. then you divide 42 by the same number 14.
