Answer:
y = 3.3x + 20
Step-by-step explanation:
-2/3x +1/5y = 4 y = mx + b
-2/3x + 1/5y = 4
-2/3 -2/3
1/5y = 2/3 + 4
1/5 / 2/3 = 3.3
1/5 / 4 = 20
y = 3.3x + 20
<span>The solution to the problem is as follows:
W=Fd=mad=425*1.8*66

Answer: 
Step-by-step explanation:
To solve this problem you must apply the proccedure shown below;
- Make the equation equal to zero:
-Add 49 at both sides:
- Now, you must take the square root of both sides of the equation, then you obtain the following roots:
- Then you have:
To avoid confusion, remember PEMDAS. This is the order of operation.
Parenthesis, Exponents, Multiply, Divide, Add, Subtract
21 ÷ 7 + 20 * 102 * 2 - 3
No parenthesis and no exponents, proceed to multiplication.
20 * 102 * 2 = 4,080
Then, perform division
21÷7 = 3
Then, do addition
3 + 4080 = 4083
Lastly, do subtraction
4,083 - 3 = 4,080
So, 21 ÷ 7 + 20 * 102 * 2 - 3 = 4,080
