Edy has $450 in her savings account. she deposits $40 each month. juan has $975 in his checking account. he writes a check for $45 each month for his cell phone bill. he also writes a check for $20 each month for his water bill. after how many months will edy and juan have the same amount of money in their accounts?

5 Months

Step-by-step explanation:

$450 + $40x = $975-$45x-$20x  (combine like terms)

450 + 40x = 975 - 65x (perform inverse operations to get only the variable on one side, what is done to one side must be done to the other)

450 + 40x + 65x = 975 - 65x + 65x

450 - 450 + 105x = 975 - 450

105x = 525 (divide both sides by 105)

x=5

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
