You mean (x-8)/3 = 3 ...right?
You would multiply both sides by 3.
Then, add 8 to both sides.
x=17
B - Since it is a dotted inequality, it would be a equal to and something else. And since it is greater than 3, it would be X is equal to or less than 3
Sari did not use the greatest common factor in the equation.
2 1/3 * 8 = 16 8/3 or 18 2/3 inches in 8 days.
Answer:
see explanation
Step-by-step explanation:
Given
2x + 7y = 42
To find the x- intercept let y = 0 in the equation and solve for x
2x + 7(0) = 42, that is
2x = 42 ( divide both sides by 2 )
x = 21 ← x- intercept or (21, 0 )
To find the y- intercept let x = 0 in the equation and solve for y
2(0) + 7y = 42 , that is
7y = 42 ( divide both sides by 7 )
y = 6 ← y- intercept or (0, 6 )
