Answer:
Step-by-step explanation:
multiply .20 with 40
which gets you 8
subtract 8 from 40
which is 32
multiply .05 with 32
which is 1.6
subtract 1.6 from 32 which gets you $30.40
Answer:
30
Step-by-step explanation:
6 x 5 is 30.
Multiply the 1st row by 3
3x−12y=−3
3x+2y=39
Subtract the 2nd row from the 1st row.
−14y=−42
Solve for y (-14y=-42)
Divide both sides by −14.
Y= -42/-14
Two negatives make a positive.
Y=42/14
Simply 42/14 to 3
Y=3
Sub y=3 into both equations
3x-12x3=-3
X=11
Therefore,
X =11
Y=3
The unknown is 2% and sorry
If the 0 and 2 are powers it would be 16^0=1, 2^2=4
Now we have 1+4*y-1.
Im not sure if you want parenthesis to make it 1+4(y-1) or not.
Solving for the first one it would simplify to 4y.
With the parenthesis it would be 4y-3.
Thats it simplified, if it is equal to something you would solve for y.
