Answer:
Probably red ball because it has higher amount
From the problem we know that Hanna saves one-half of her paycheck each week, so she saves

. Also, we know that her parents put $50 in her savings account each week, so the total amount she and her parents put in her saving's account is

.
Since we know that Hanna currently has <span>$1,280 in her saving's account and each week she and her parents deposit $130 to the account, with </span>

representing the number of weeks, we can model the situation as follows:
6x+x-8=90 because right angle
7x=98 combine like terms
7x/7=98/7
X=14
m<1=6*14=84
m<2=14-8=6
Answer:
-1 and 9
Step-by-step explanation:
To solve the quadratic, factor and set its factors equal to 0. Factoring is the action of breaking up a polynomial into pieces which multiply to make it. The factors are found by multiplying numbers to make C and add to B of
.
Here c = -9 and b = -8. The numbers -9 and 1 multiply to -9 and add to -8. These are the factors (x-9)(x+1).
Set each equal to 0 and solve for x.
x-9 = 0
x = 9
x+1 =0
x = -1
