Answer:
7 weeks
Step-by-step explanation:
Given data
Alyssa starts with $30 and saves $5 each week
let the number of weeks be x
y= 30+5x----------1
Bill has $16 and saves $7 each
week.
y= 16+7x----------------2
equate 1 and 2
30+5x= 16+7x
30-16= 7x-5x
14= 2x
x= 14/2
x= 7 weeks

The sum of two numbers is 46 and their
difference is 20. What is the smaller
number?
1
A) 40
B) 13
C) 26
D) 12
Answer:
B. 13
Step-by-step explanation:
We have two unknown numbers, let's have two variables for these two unknown numbers, X and Y.
"The sum of two numbers is 46 and their difference is 20."
Meaning we have two equations :
X + Y = 46
X - Y = 20
Looking at the last part of "their difference is 20." We can assume X = Y + 20
So substitute the assumed equation into X + Y = 46
(Y + 20) + Y = 46
2y + 20 = 46
Subtract 20 from both sides :
2y = 26
Divide 2 by both sides :
y = 13
There you go.
Use the Distributive Property to solve the equation.
- 8(x + 7) = 16
Apply the Distributive Property and simplify.
- 8(x + 7) = 16
- 8x + = 16
Answer:
x= - 9
Step-by-step explanation:
- 8(x +7) = 16-8x - 56 = 16 -8x = 16 + 56-8x = 72x = 72 ÷ (-8) x = -9Hey there!
Use the Distributive Property and simplify:
-8(x+7)=16
-8x-56=16
Notice we write -8 right next to x.
Add 56 to both sides:
-8x=16+56
-8x=72
Divide both sides by -8:
x=-9
Hope everything is clear.

What does the quadratic function
f(x) = x2 - 6x + 8 look like when it is
rewritten in the form f(x) = a(x − p)2 +q?
Answer:
f(x) = (x -3)^2 - 1
Step-by-step explanation:
f(x) = x^2 - 6x + 8
a = 1, b = -6 and c = 8
So we are finding half of the b equation (ignore the negative sign)
Half of 6 is 3, so we are going to square 3 (3^2 = 9) and add 9 to the left side and subtract 9 to the right side
(x) = (x^2 - 6x + 9) + (8 - 9)
You can tell the polynomial is a perfect square, so we will have to factor it using the perfect square method
(x^2 - 6x + 9)
square toot of x^2 is x and square root of 9 is 3 and the operation sign after the a number is a minus sign
(x -3)^2
Don't forget the rest of the equation from before
(x -3)^2 + (8 - 9)
(x -3)^2 - 1
So the equation is f(x) = (x -3)^2 - 1

Andre is making paper cranes to decorate for a party. He plans to make one large paper
crane for a centerpiece and several smaller paper cranes to put around the table. It takes
Andre 10 minutes to make the centerpiece and 3 minutes to make each small crane. He will
only have 30 minutes to make the paper cranes once he gets home.
1. Andre wrote the inequality 3x + 10 < 30 to plan his time. Describe what x, 3x, 10,
and 30 represent in this inequality.
Answer:
x is the number of small cranes he can make
3x is the amount of time it takes to make all of those small cranes
10 is the amount of time it takes to make just the centerpiece
30 is how much time in total he has to make all of the paper cranes
Step-by-step explanation:

The difference in the price of 2 backpacks is $19.30. If one backpack costs $39.00, which of the answer choices could represent the price of the other backpack?
Answer:
$19.70 OR $58.30
Step-by-step explanation:
I say either or because I can't see the answer choices.
Its either adding or subtracting from the one backpack we know is $39.00
If we know the difference between the two is 19.30
39.00+19.30 = 58.30
39.00-19.30= 19.70
See if either of those are available :) Hope this helps! :)
Answer:
$19.70

Serenity invested $3,100 in an account paying an interest rate of 2.9% compounded continuously. Assuming no deposits or withdrawals are made, how much money, to the nearest dollar, would be in the account after 12 years?
Answer:
$4179
Step-by-step explanation:
3,100*.029= 89.9
89.9*12=1,078.80
3,100+1,078.80=4,178.80
4,178.80 rounded to the nearest dollar= 4179
The amount of money in the account after 12 years would be $4,371.
What is Compound interest?Compound interest is defined as interest paid on the original principal and the interest earned on the interest of the principal.
To calculate the amount of money in the account after 12 years, we need to use the formula for continuously compounded interest, which is:
A = P[tex]e^{rt}[/tex]
where A is the final amount, P is the principal (initial amount invested), r is the annual interest rate, and t is the number of years the money is invested.
In this case, the initial amount invested is $3,100, the annual interest rate is 2.9%, and the number of years is 12.
Plugging these values into the formula, we get:
A = $3,100 × [tex]e^{0.029 \times 12)[/tex]
A = $3,100 × [tex]e^{0.348}[/tex]
A = $3,100 × 1.41
A = $4,371
Therefore, the amount of money in the account after 12 years, to the nearest dollar, would be $4,371.

e is 5 more than d
f is 7 less than d
work out e-f
Answer:
12
Step-by-step explanation:
(5+d)-(d-7)
5--7 = 5+7 = 12
To prove this:
d = 10
e = 5+10 =15
f = 10-7 = 3
15 - 3 =12
