Here we have , Hiking up a mountain, you notice that the air temperature drops 10 degrees every 1000 meters increase in elevation . We need to find Write a multiplication expression to represent the decrease in temperature if you hike up the mountain 3000 meters. Let's find out:

For every 1000 meters rise in elevation , there is decrease in 10° of temperature . So , For rise in n meters in elevation , there is decrease in n×10° of temperature i.e

Decrease in temperature = (n/1000)×(-10) i.e.

⇒ (n/1000)×(-10)

⇒ $\frac{n}{1000}(-10)$

At n = 3000 meters:

⇒ $\frac{3000}{1000}(-10)$

⇒ $3}(-10)$

⇒ $-30$ °

Therefore , decrease in temperature if you hike up the mountain 3000 meters is $-30$ ° .

A tire dealer sells all-season tires for $68 each and all-terrain tires for $125 each. In one day, the sales both tires totaled

Anettt [7]

Start by making variables to represent each tire
S=all-season tires
T=all-terrain tires
Create equations based on what was given in the question
68s+125t=3926 (the price for each tire multiplied by the number of tires equals the overall sales price)
T=14 (14 all-terrain tires were sold)
Sub 14 into the first equation for t in order to solve for s
68s+125(14)=3926
68s+1750=3926
68s=3926-1750
68s=2176
S=32
I hope this helps!
