I'm guessing that you meant to type 4(x - 3). If that's the case, then you can solve this using the Distributive Property.
4(x - 3) Multiply the number on the outside of the parentheses by both of the numbers on the inside.
(4 · x) - (4 · 3)
(4x) - (12) Now, simplify by taking out the parentheses.
4x - 12
Answer: It’s C
Step-by-step explanation:
I did the test
The time it takes for a certain object or person, in this case Georgia, to travel from one place to another is the quotient of the distance and speed. Such that the given above can be best represented by the equation below,
42 minutes = (7/8 + 5/6 + x) / 1/18
The value of x from the equation is approximately 0.625 miles.
Answer:
x = 4
y = 2
Step-by-step explanation:
by using substitution method ;
now, in second equation ;
- 2x + 3y = 14
- 2 (8 - 2y) + 3y = 14
( since x = 8-2y, from equation 1 )
- 16 - 4y + 3y = 14
- 16 - y = 14
- -y = 14 - 16
- -y = -2
- y = 2
<em>i</em><em> </em><em>hope</em><em> </em><em>it</em><em> </em><em>helped</em><em>.</em><em>.</em><em>.</em>
putting value of y in equation 1, we get :
- x + 2y = 8
- x + (2 × 2) = 8
- x + 4 = 8
- x = 8 - 4
- x = 4
