I dont know anything about the 5 step problem solving plan...
but ur equation is : y = 6x...where y is total saved and x is number of weeks.
when she has a total of 60 bucks....so y = 60
60 = 6x
60/6 = x
10 = x....so it would take her 10 weeks <==
Answer:
4
Step-by-step explanation:
thx for the points lol
5sqrt(x+7)=-10
Dividing both sides by 5:
5sqrt(x+7)/5=-10/5
sqrt(x+7)=-2
Squaring both sides of the equation:
[sqrt(x+7)]^2=(-2)^2
x+7=4
x+7-7=4-7
x=-3
Replacing in the original equation:
5sqrt(x+7)=-10
5sqrt(-3+7)=-10
5sqrt(4)=-10
5(2)=-10
10=-10 It's not equal, then x=-3 is an extraneous solution
