After about 12 months both Caitlyn and Santos will have the same balance of 150 dollars in their bank account.
Step-by-step explanation:
Caitlyn's saving: -5x+210
Santos' saving: 5x+90
To know when the total amount in their bank account is the same you would need to make these linear equations equal to one another.
-5x+210 = 5x+90
(Add 5x on both sides)
210=10x+90
(Subtract 90 from both sides)
120=10x
(Simplify)
x=12
After about 12 months their total savings should be the same. To check what their balance will be plug the x value of 12 into both of these equations. This should give 150 as your answer for both equations.
Pam and her brother both open savings accounts. each begin with a
balance of $0. For every $2 is that Pam saves in her account her brother
saves $5 in his account
P:bro=2:5 when P=40 what is bro?
2/5=40/b times 5b both sides 2b=200 divide 2 b=100 bro has $100 not sure what tape diagram is
