Answer:
The average change in temperature over the last four days is 0.3°C
Step-by-step explanation:
We need to find the average daily change of temperature in the city over the 4 days. For this we find the change in temperature over the last 4 days and average it.
The temperature in the last 4 days are 1.34°C,-°C, -0.75°C and
°C.
Change between first and second day = 1.34 + - = 2.05
Change between second and third day = -0.71 + 0.75 = 0.04
Change between third and fourth day = - 1.19
Average change = = 0.3°C

<u>Answer: </u>
Expression x + 2my + z represents cost of order where x, y, z are cost of small , medium and large drinks (in dollars) respectively.
<u>Solution: </u>
Given that
Juan’s family ordered a small drink and m medium drinks.
Alex family ordered m medium drinks and a large drink.
Need to write an algebraic expression which shows total cost of both order in dollars.
Let’s assume cost of one small drink = x
And assume cost of one medium drink = y
And assume cost of one large drink = z
So now cost of order of Juan’s family is equal to cost of 1 small drink + cost of m medium drinks = 1 x + m
y
= x + my
And cost of order of Alex family is equal to cost of m medium drinks + cost of one large drink
= m x y + 1 x z
=my + z
So total cost of both order in dollars = x + my + my + z = x + 2my + z
Hence expression x + 2my + z represents cost of order where x , y , z are cost of small , medium and large drinks (in dollars) respectively.
