Harita must memorize 90 measures of music for her cello solo at a concert. she plans on memorizing 18 new measures for
every 3 days of practice. which equation can be used to determine m, the number of measures harita still needs to
memorize, as a function of d, the number of days of practice since she began learning the piece?
om = 72 - 150
om= 90 - 60
om = 101 - 210
om= 108 - 3d
what is d?

m = 90 - 6d is the equation to determine m, the number of measures Harita still needs to  memorize, as a function of d, the number of days of practice since she began learning the piece

Solution:

Given that Harita must memorize 90 measures of music for her cello solo at a concert

To find: equation to determine m, the number of measures Harita still needs to  memorize, as a function of d, the number of days of practice since she began learning the piece

Let "m" be the number of measures Harita still needs to  memorize

Let "d" be the number of days of practice since she began learning the piece

Given that She plans on memorizing 18 new measures for  every 3 days of practice

Rate per day is given as:

Therefore she memorises 6 per day

Therefore, the equation that relates 'm' to 'd' is:

m = total measures of music she must memorise - (number of measures she memorises per day x d)

m = 90 - 6(d)

m = 90 - 6d

Thus the required equation is found

the answer is somewhere there guys it really . there im just not gonna answer

step-by-step explanation:

but i'm guessing ur first option tho

570, the answer is 570, hope it
