How do you create and solve equations in one variable given a real–world situation?

WINSTONCH [101]

Step-by-step explanation:

1) first eliminate constant(number without variable) you eliminate constant by doing the inverse operation(if constant is being added, then subtract)(if constant is being subtracted, then add it)

ex: if x+9=32

subtract 9 from both sides to get rid of it

x=23

2) if there is another constant but this constant is being multiplied/divided then do the opposite operation to remove it

you could multiply by 3 on both sides:

x+9=69

x=60

On a map, the distance between two towns is 3.4 inches. The map scale is 2 inches: 25 miles. What is the actual distance between

Mariulka [41]

For this question we can solve it by setting up a proportion:

$\frac{2inches}{25 miles}= \frac{3.4inches}{x}$

Now we can solve for x to find the total distance between the towns. Let's cross multiply and solve for x:

$2x=85$
$x=42.5miles$

So now we know that the total distance between the towns is 42.5 miles.

Can someone pls Help me with geometry

RUDIKE [14]

∠P = 6x + 6

∠Q = 2x + 11

∠R = 2x + 3

∠P + ∠Q + ∠R = 180

(6x + 6) + (2x + 11) + (2x + 3) = 180

10x + 20 = 180

10x = 160

x = 16

∠Q = 2x + 11 = 2(16) + 11 = 32 + 11 = 43

Answer: 43°

4x^2+12x+9-2x^2-7x-15

Ilia_Sergeevich [38]

4x^2 + 12x + 9 - 2x^2 - 7x - 15

4x^2 - 2x^2 = 2x^2
12x - 7x = 5x
9 - 15 = -6

2x^2 + 5x - 6
