Answer:
22.5
Step-by-step explanation:
Simplify the expression. Write the answer in scientific notation. left parenthesis 9 times 10 Superscript negative 4 right parenthesis left parenthesis 6 times 10 Superscript negative 5 right parenthesis(9×10−4)(6×10−5)
Difference between x and y is 25
lets say x is bigger
x-y=25
smaller is 1/6 of larger
y=x/6
sub x/6 for y in other equation
x-(x/6)=25
times both sides by 6
6x-x=150
5x=150
divide both sides by 5
x=30
y=x/6
y=30/6
y=5
the smaller number is 5
Answer:
C is the answer
C ) y = 
Step-by-step explanation:
2 y - x = 
( -y + 1)
(2 y - x ) 4 = 3 ( -y +1)
8 y - 4 x = -3 y + 3
8 y + 3 y = 4 x + 3
11 y = 4 x + 3
∴ y = 
76 or 77. 2/3 times x/115. 2 times 115 is 230. 230 divided by 3 is 76.6666666667.
