Answer: 10 weeks
Step-by-step explanation:
Nilda's money = 250 +15x being x the number of weeks that have passed
Lona's money= 200+20x
If they have the same amount, then
250+15x=200+20x
250-200=(20-15)x
50=5x
50/5=x
10=x
SOLUTION
From the question given, the cost of the toy truck is $36.50 before tax.
Now, the store selling the toy truck adds a 6% sales tax. This means

Now, we will add this $2.19 to the initial cost, we have

This gives $38.69.
Finally we will do a discount of 10%. 10% discount is

We will then subtract this 3.869 from 38.69, we get

That is 34.821. The 1 which is the last number at the decimal part is less than 5, so we ignore it and our answer becomes $34.82

Answer:
0.44
Step-by-step explanation:
-3x^2 + 2y^2 + 5xy - 2y +5x^2 - 3y^2
Combine like terms
-3x^2 + 5x^2 = 2x^2 2y^2 - 3y^2 = -1y^2
2x^2 - 1y^2 + 5xy - 2y
Now plug in the solutions Note: it is easier if you have all decimals or all fractions (-1/10=-.1
2(0.5)^2 - 1(-0.1)^2 + 5(0.5)(-0.1) - 2(-0.1)
Simplify:
0.5 - 0.01 - 0.25 + 0.2
0.5 + 0.2 - 0.01 - 0.25
0.7 - 0.26
0.44
