$3a-4a+9=-12a+43-6a$
$-a+9=-12a+43-6a$
$-a+9=-18a+43$
$-a+9+18a=43$
$17a+9=43$
$17a=43-9$
$17a=34$
$a=34:17$
$a=2$

The answer is: a=2

Solve for x

ludmilkaskok [199]

Answer:

x = 3/4

Step-by-step explanation:

Step 1: Write equation

5x - 2(x + 1) = 1/4

Step 2: Solve for x

Distribute -2: 5x - 2x - 2 = 1/4
Combine like terms: 3x - 2 = 1/4
Add 2 to both sides: 3x = 9/4
Divide both sides by 3: x = 3/4

Step 3: Check

Plug in x to verify it's a solution.

5(3/4) - 2(3/4 + 1) = 1/4

15/4 - 2(7/4) = 1/4

15/4 - 14/4 = 1/4

1/4 = 1/4

Sin cos and tan help

Nikitich [7]

Sin(B) = opp/hyp = 32/40 = 0.8
cos(B) = adj/hyp = 24/40 = 0.6
tan(B) = opp/adj = 32/24 = 1.33 (repeating)

The scale on a map says that 6 cm represents 15 km. What distance on the map in centimeters represents 20 kilometers?

ale4655 [162]

Answer:

8 centimeters.

Step-by-step explanation:

$6cm\ on\ map\ -> 15km\\$

Divide 3 both sides:

$2cm\ on\ map\ -> 5km$

Multiply 4 on both sides:

$8cm\ on\ map\ -> 20km$

8cm on the map represents 20km.
