Answer:

1,000 miles

Step-by-step explanation:

set up the equation as

100x = d

where x equals the number of half inches between two points on the map

and d equals the distance between those points in real life

5 inches = 10 half inches so, plugged in the equation looks like

100(10) = d

simplify it to

1000 = d

and bam, the real distance is 1,000 miles

Mandarinka [93]

Answer:

The equation is 0.11x + 0.25 = 0.15x (I think) and the answer is 6.25 = x

Step-by-step explanation:

0.11x + 0.25 = 0.15x  Subtract 0.11x from both sides

-0.11x              -0.11x

0.25 = 0.04x Divide both sides by 0.04

6.25 = x

Let f(x) = 5x2 – 4x and g(x) = 5x + 1.
Nastasia [14]

f(x) = 5x^2 - 4x

g(x) = 5x + 1

Therefore f - g = 5x^2 - 4x - (5x + 1)

= 5x^2 - 4x - 5x -1

= 5x^2 -9x - 1


Hope it helps :)
