Five friends go to the movies. They each pay $9 to get in and $8 for a popcorn and drink combo. a) Write two different expressions to find the total cost of the outing.

b) Evaluate each expression. Which expression was easier to evaluate? Justify your choice.

x=5(9+8)

add 9+8 to get 17

multiply 17 by 5

$85

(5x9)+(5x8)=x

multiply 5x9 to get 45

multiply 5x8 to get 40

add 45 and 40

$85

The first expression was easier to evaluate because it required less steps.

Hope this helps :)

d. millimeters per hour.

step-by-step explanation:

we are given that,

carlo used a rain gauge to measure the amount of water his lawn is receiving from the sprinklers.

since, according to the options, we see that,

water cannot be measured by 'miles per hour', 'meters per second' and 'grams per seconds'.

we get that, the water can be measured by 'millimeters per hour'.

hence, the appropriate rate for describing the amount of water is 'millimeters per hour'.

42%

step-by-step explanation:

we know,

total people = 60

total males = 25

percentage of males

= 25/60 × 100

= 25/6 × 10

= 25/3 × 5

= 125 / 3

= 41.

rounding of = 42%
