3x + 6y= 180What is x and y​

Mathematics
1 answer:
Diano4ka-milaya [45]3 years ago
3 0

Answer and explanation:

<h2>X</h2>

3x + 6y = 180  <em>Use the original expression to find x</em>

3x = 180 - 6y  <em>Subtract 6y by both sides</em>

\frac{3x}{3} = \frac{180}{3} - \frac{6y}{3}  <em>Divide by 3 to get x</em>

x = 60 - 3y

<h2>Y</h2>

x = 60 - 3y  <em>Use the new expression to find y</em>

x - 60 = - 3y  <em>Subtract 60 by both sides</em>

\frac{x - 60}{-3} = \frac{-3y}{-3}  <em>Divide by -3 to get y</em>

-\frac{x}{3} + 20 = y

Todd’s average score for six tests was 92. If the sum of the scores of two of her tests was 188, then what was her average score
natita [175]

Answer:

91

Step-by-step explanation:

Todd’s average score for six tests = 92.

The sum of two of her test = 188

First, we need to find the total score for the six test. This given below:

Average = sum of all test / number of test

sum of all the test = average x number of test

average score for six tests = 92.

Number of test = 6

Sum of all the Tests = 92 x 6 = 552

Sum of four test = sum of all the test — sum of two test

Sum of four test = 552 — 188 = 364

Now we can solve for the average of the other four test as shown below:

Average of four test = 364/4= 91
