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?

m = 72 – 15d
m = 90 – 6d
m = 101 – 21d
m = 108 – 3d

m = 90 – 6d

Explanation:-

Total measures of music for cello solo at a concert=90

Number of measures she memorize music for cello solo at a concert in 3 days=18

⇒Number of measures she memorize music for cello solo at a concert in 1 day=

Thus the equation can be used to determine the number of measures can be m=total measures-6 times days=90-6d

∴m=90-6d

13

step-by-step explanation:

169-1=168

168-3=165

165-5=160

160-7=153

153-9=144

144-11=133

133-13=120

120-15=105

105-17=88

88-19=69

69-21=48

48-23=25

25-25=0

since it took 13times to completely subtract it hence its square root is 13
