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

Anais bought 4 1/2 yards of ribbon. She had 3 feet 8 inches of ribbon left after trimming some curtains. How many inches of ribbon did anais use to trim the curtains
Answer:
First convert all numbers into inches since that is the answer being solved for.
1 yard =36 inches
4.5 x 36 = 1,620 inches
1 foot = 12 inches
3 x 12 = 36 inches
36 + 8 = 44 inches
Now take 1,620 inches (starting ribbon measure) and subtract 44 inches (what was left over) to get the inches used to trim curtains.
1,620 inches - 44inches =
1,576 inches were used to trim the curtains.

Isabella and her cousin Rodrigo have the same birthday but isabella is 15 years older than Rodrigo the equation y= x + 15 represents isabella's age y, when Rodrigo is x years old what is the answer?.
Answer:
The answer is below
Step-by-step explanation:
Isabella and her cousin rodrigo have the same birthday, but isabella is 15 years older than rodrigo is x years old. which table of value shows this relationship
Solution:
Let x represent Rodrigo's age and let y represent Isabella's age. Since Isabella is 15 years older than Rodrigo, hence her age is given by the equation:
y = x + 15
You can use a table to represent the relationship between their ages. Let us find the corresponding Isabella age for the following Rodrigo age.
Rodrigo: 10 20 30
Isabella: 25 35 45
When x = 10: y = x + 15 = 10 + 15 = 25
When x = 20: y = x + 15 = 20 + 15 = 35
When x = 30: y = x + 15 = 30 + 15 = 45

P=-30h+74 The variable h represents the number of hours he has spent reading, the variable p represents the number of pages left to read. How many hours of reading will Ethan have to do in order to have 14 pages left to read?
Answer: Ethan will have to spend 2 hours reading if 14 pages are left to read
Step-by-step explanation:
Given the equation
P=-30h+74
where p =number of pages left to read and
h= the number of hours he has spent reading
Therefore , if Ethan has 14 pages left to read, then the number of hours Ethan will have to read will be
P=-30h+74
14= -30h + 74
30h= 74-14
30h= 60
h = 60/30
h =2 hours
Ethan will have to spend 2 hours reading if 14 pages are left to read

Solve
7 + X = 2x-5
3
Answer:
x = 60
Step-by-step explanation:
subtract 7 from both sides:
7 + x - 7 = 2x - 53 - 7
Simplify:
x = 2x - 60
Subtract 2x from both sides:
x - 2x = 2x - 60 - 2x
Simplify:
-x = -60
Divide by -1=
-x/-1 = -60/1
X = 602. Which statement is not true in the equation
y = 0.5x?
A. The value of y is one-half times the value of x.
B. The equation represents an additive relationship.
C. The value of y is 4 when the value of x is 8.
D. The equation represents a multiplicative
relationship.
Answer:
B
Step-by-step explanation:
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.

Margo added three multi-digit decimal numbers. The first number was 5.19. The second number was 10 times the first number. The third number was 10 times the second number. What was the sum?
Answer: 576.09
Step-by-step explanation:
First number = 5.19.
The second number was 10 times the first number which will be:
= 5.19 × 10
= 51.9
The third number was 10 times the second number. Thus will be:
= 51.9 × 10
= 519
The sum of the numbers will be:
= 1st number + 2nd number + 3rd number
= 5.19 + 51.9 + 519
= 576.09
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.

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
