If you get a 50/60 on a test, what percentage is that equal to?
Yuliya22 [10]

Answer:

83%

Step-by-step explanation:

To convert fraction to percents, you have to divide the numerator by the denominator.

So 50 divided by 60 = .833333333333333

Now you have to convert this decimal to a percent by moving the decimal point 2 spaces to the right.

83.333333333%

On tests they usually round percents to the nearest whole percent.

So it would just be 83%

Solve the system algebraically. y = 3 -1/2 x 3x + 4y = 1 What is the value of x?
4vir4ik [10]

Answer: x=-11

Step-by-step explanation:

You can use the Method of substitution.

Substitute the equation y=3-\frac{1}{2}x into the equation 3x + 4y = 1 and then you must solve for the variable x:

3x + 4y = 1\\\\3x + 4(3-\frac{1}{2}x) = 1\\

Apply Distributive property:

3x + 12-\frac{4}{2}x = 1\\3x+12-2x=1

Subtract 12 from both sides of the equation and then add the like terms. Then you get:

3x+12-2x-12=1-12\\3x-2x=-11\\x=-11
