What is 3+0.5(4a+8)=9-2a is your solving for (a).

Nady [450]

Answer:

$a = 1/2$

Step-by-step explanation:

Step 1: Distribute

$3 + 0.5(4a + 8) = 9 - 2a$

$3 + (0.5 * 4a) + (0.5 * 8) = 9 - 2a$

$3 + 2a + 4 = 9 - 2a$

Step 2: Combine like terms

$(3 + 4) + 2a = 9 - 2a$

$7 + 2a = 9 - 2a$

Step 3: Subtract 7 from both sides

$7 + 2a - 7 = 9 - 2a - 7$

$2a = 2 - 2a$

Step 4: Add 2a to both sides

$2a + 2a = 2 - 2a + 2a$

$4a = 2$

Step 5: Divide both sides by 4

$4a / 4 = 2 / 4$

$a = 1/2$

Answer: $a = 1/2$

What is the equation of this line? y = -4× y = 4× y = - 1/4× y = 1/4×

sashaice [31]

The answer is the third choice: y=-1/4x.

We find this by remembering that slop is rise over run. Since the rise is -1 and the run is for we can make it -1/4 as the slope, which is next to the x term. Since the y intercept is at the origin we do not have a b term from the formula y=Mx+b.
