5x – 12 = 13<br><br> 8(x + 3) = 64<br><br> using algebra

loris [4]

Answer:

A) 5 and B) 5

Step-by-step explanation:

A) 5x-12=13

+12 +12 (add 12 to the 13)

5x=25

(then divide 25 by 5 which is 5 so the answer is 5)

B) 8(x+3)=64 (first use distributive property)

8x+24=64

-24 -24 (then subtract 24 to 64 which is 40)

8x=40

(then divide 40 by 8 which is 5 so that is it!)

I believe this is correct, I hope this helps :D

Answer:

Salamander trail is longer than great oaks trail.

Step-by-step explanation:

We have the data from two different maps of the same park.

In the first map the length of great oaks trail is 4.5 cm

The scale from the park to the map is 36 mi to 6 cm ⇒

We can find the real length of great oaks trail writing the following equivalence :

$\frac{36mi}{6cm}=\frac{x}{4.5cm}$

Where x is the real length of great oaks trail ⇒

$x=\frac{(36mi).(4.5cm)}{6cm}=27mi$

We find that the real length of great oaks trail is 27 mi

In the second map the length of salamander trail is 3.5 cm

The scale from the park in the second map is 24 mi to 3 cm.

Again we can find the real length of salamander trail writing the equivalence :

$\frac{24mi}{3cm}=\frac{y}{3.5cm}$

Where y is the real length of salamander trail ⇒

$y=\frac{(24mi).(3.5cm)}{3cm}=28mi$

We find that the real length of salamander trail is 28 mi.

Therefore salamander trail is longer than great oaks trail.
