What is y=x+10 in Standard Form?<br><br> ASAP please, thanks!
Allushta [10]
The standard form is Ax + By = C

Given the linear equation, y = x + 10, we must transpose x to the left-hand side of the equation:

- x + y = x — x + 10

- x + y = 10

Next, we must multiply both sides by (-1) because A must be positive:

(-1) (- x + y) = 10 (-1)

This leads to:

x — y = -10 in standard form, Ax + By = C

The average of 7 numbers is 60. The average of the first three numbers is 50, while the average of the last three is 70. What mu
Svetradugi [14.3K]

From the last two facts, we get

\dfrac{x_1+x_2+x_3}3=50\implies\dfrac{x_1+x_2+x_3}7=\dfrac{150}7

\dfrac{x_5+x_6+x_7}3=70\implies\dfrac{x_5+x_6+x_7}7=30

Then

\dfrac{x_1+x_2+\cdots+x_6+x_7}7=60\implies\dfrac{x_4}7=60-\dfrac{150}7-30\implies\boxed{x_4=60}
