Answer:
1)Solving the expression we get
2) solving the equation we get
Step-by-step explanation:
We need to solve the expressions:
1)
Solving
First solving the brackets
Simplifying
Adding 4x on both sides
Switching the sides
Divide both sides by 3
So, Solving the expression we get
2)
Solving:
Adding 6.1 on both sides
Adding 2.4x on both sides
Divide both sides by 6
So, solving the equation we get
10^-3 means move decimal place 3 places to left or divide by 1000
move decimal place 3 places left
0.0030205 is normal form
<u><em>10:45-12:20=</em></u>
<u><em>1:35 Is the Correct answer</em></u>
Answer:
(9, 6)
Step-by-step explanation:
add equations together: (x + y = 15) + (x - y = 3) --> x + x + y - y = 15 + 3 --> 2x = 18
isolate the variable: 2x/2 = 18/2 --> x = 9, so the x-coordinate is 9
substitute 9 in x's place in one of the equations: 9 + y = 15
solve for y: y = 15 - 9 --> y = 6, so the y-coordinate is 6
combine x and y coordinates together: (9, 6)
The answer is C. 1/5 and 1
