Savvas Realize Tonya’s dog-walking service charges a flat rate of $20 per month, plus $3 per mile that each dog is walked. Beth does not charge a monthly fee for her dog-walking service, but she charges $5 per mile that each dog is walked.
Part A
Choose the equation that can be used to find the number of miles m for which Tonya and Beth would charge the same amount.
A. 20 + 3m = 5m
B. 20 = 3m + 5m
C. 20 + 5m = 3m
D. 20 + m = 8m
Part B
m = _____ miles
Answers
Answer:
A 10 miles
Step-by-step explanation:
If I'm not mistaking I'm pretty sure we can write the two problems with an equal sign between as we're trying to find the same amount.
Using this information, we know that we Automatically have a +20 charge with a 3 dollar charge for every mile walked. Now we have 20+3x=
Now we plug in the 5x to get 20+3x=5x
From here you subtract 3x and you get 20=2x. Now divide!
10=x
Hope this helps! (Side Note: You should probably get some sleep as I'm sure it's pretty late where ever you live. Also, keep trying even if you feel like giving up!) :)

Answer:
(a) 0.00000221 (b) 4.2 x
Step-by-step explanation:
(a) means you need to move the decimal left (because of the negative) 6 spaces. So you have 2.21 move the decimal 6 spaces left and you end up with 0.00000221
(b) If you have 420,000 and you count 5 spaces from the last number, that leaves the decimal inbetween the 4 and 2 so your answer will be 4.2 x

Answer: 3/7
Here are two methods to solve this problem.
1. Count on, since you have the same denominator.
1/7, 2/7, 3/7.
2. Add, but not counting on.
1 + 2 = 3
3 = 3/7.
Hope it helps!

Based on the calculations, the equation of this parabola is equal to: A. y = -3(x + 3)² + 6.
How to determine the equation of a parabola?
Mathematically, the standard equation with the vertex for any parabola is given by:
y = a(x - h)² + k.
where:
- h and k are the vertex.
- a is a point.
Substituting the given parameters into the formula, we have;
y = -3(-3 - (-3))² + 6
y = -3(x + 3)² + 6

A is your answer
(-3,6) must be a point of the curve.
A) if x=-3 then y=-3(-3+3)²+6=6
y'=-3(x+3)=0==>x=-3
and y=6
B) if x=-3 then y=-3(-3+3)²-6=-6 and not 6
C) if x=-3 then y=-3(-3-3)²+6=-3*36+6= -102 and not 6
D) -3(-3-3)²-6=-3*36-6=-114

p ... profit
g ... glasses of lemonade
f(g) = p = g * $1 - $50
The correct result would be f(g) = g * $1 - $50.
Answer with explanation:
Amount charged to Betty for Lemonade Stand = $ 50
Amount charged by Betty for a glass of Lemonade= $ 1
Variable , P is used to denote Profit.
Variable, g , is used to denote number of glasses of Lemonade Sold.
If Betty wants to make a profit, then
→ g (Number of glasses of lemonade Sold) > 50
⇒Profit (P)=[Number of glasses of Lemonade Sold (g)>50]×$ 1 -$50
→ P=g -50, where, g >50,that is a positive integer,greater than 50.
Set up Cost , of $ 50 is represented by the function , f(g).
So, the above function changes to
→ P = g - f(g)
