The <em>correct answers</em> are:
It would take 5 months and she would save $250.
Explanation:
Let m be the number of months.
For the first way of saving, $200 up front and $10 each month, the expression would be
200+10m.
For the second way of saving, $100 up front and $30 each month, the expression would be
100+30m.
Setting them equal gives us the equation
200+10m = 100+30m
Subtract 10m from each side:
200+10m-10m = 100+30m-10m
200 = 100+20m
Subtract 100 from each side:
200-100 = 100+20m-100
100 = 20m
Divide both sides by 20:
100/20 = 20m/20
5 = m
It would take 5 months.
$200 up front and $10 each month for 5 months:
200+10m
200+10(5)
200+50
250
She would save $250.
Answer:
12/7
Step-by-step explanation:
Make 5 1/7 into improper fraction
(5×7)+1= 36/7
Then make 3 as a fraction
3/1
Divide
36÷3
7÷1
First we rewrite the expression:
(4x ^ 3) * (2x) ^ - 4
Using properties of exponents we have:
(4x ^ 3) / (2x) ^ 4
Rewriting:
(4x ^ 3) / 16x ^ 4
(x ^ 3) / 4x ^ 4
(1) / (4x)
answer:
An equivalent expression is:
(1) / (4x)
option 1
Answer:
The answer to your question is the letter D. (step 2)
Step-by-step explanation:
Data
P (7, 4) slope = 6
Process
1.- Write the equation of the line
y - y1 = m(x - x1)
x1 = 7 y1 = 4
2.- Substitution
y - 4 = 6(x - 7)
- Simplification
y - 4 = 6x - 42
- Solve for y
y = 6x - 42 + 4
y = 6x - 38 This is the equation in the point-slope form
3.- According to the choices the answer is letter D.
