Joy and joanna both purchase party invitations. They both spent the same amount of money. Joy spent $.75 per invitation and $3.25 on shipping and handling. Joanna spent $.50 on each invitation and $6.00 on shipping and handling. How many invitations did each girl purchase?

11 invitations each

Step-by-step explanation:

Let the number of invitations they bought be x .

Since they spent the same amount of money, Their total costs would be the same. Hence ;

3.25 + 0.75(x) = 0.5x + 6

0.75x - 0.5x = 6 - 3.25

0.25x = 2.75

x = 2.75/0.25

x= 11 invitations

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'.

false

step-by-step explanation:

the reason i say this is because for a certain length of sides you can pick any two and the length is wither equal or greater than the third side and in this case it's not.

3 + 5 = 8

8 is smaller than 9 which is the third side.

hope this : )
