Katie empties her purse and finds that it contains only nickels (worth 5 cents each) and dimes (worth 10
cents each). If she has a total of 7 coins and they have a combined value of 45 cents, how many of each coin
does she have?
Answer:
Step-by-step explanation:
2 dimes and 5 nickels
Dimes: 10 × 2 = 20
Nickels: 5 × 5 = 25
Answer:
5 nickel and two dimes
Step-by-step explanation:
let let X be the number of Nickels
number of X is equals to 7 - x
5x+ 10*(7-x)= 45
X= 5
thus nickel is 5 and dimes is 2

= 16-5
=11
Find the percent increase. Round to the nearest percent.
Percent change= Amount of change
Original Amount
=11/5
=2.2
=220%

Tyler incorrectly says that the constant term of (x + 4)(x - 4) is zero.
a. What is the correct constant term?
b. What is Tyler's mistake? Explain your reasoning.
Answer:
a. -16 is the constant
b.if you expand the equation it would be x^2-16, and the constant is -16
Solving the expression (x + 4)(x - 4) ; the constant term in the expression is - 16 and not 0
To solve, we need to expand the expression : (x+4)(x-4)
Expanding the expression :
(x + 4)(x - 4)
Opening the bracket :
x² - 4x + 4x - 16
x² - 16
The constant term in the expression, is - 16 as it is the value without a variable.
Therefore, Tyler's mistake is incorrectly stating that the constant value is 0 instead of - 16

Step-by-step explanation:
Given h(x) = 4x – 5, solve for x when h(x) = 7.
Answer: x = 3 when h(x) = 7.
Step-by-step explanation:
h(x) = 4x -5 To solve for x when h(x) = 7, you will set the expression 4x -5 equals 7 to solve for x.
4x -5 = 7 Add 5 to both sides
+5 +5
4x = 12 Divide both sides by 4.
x= 3

What is f(x)= 3x+ 13(17x-7) if x equals 4?
Answer:
805
Given:
x=4
Step-by-step explanation:
f(x) = 3x + 13(17x-7)
f(x) = 3 × 4 + 13(17 × 4 - 7)
f(x) = 12 + 13(68 - 7)
f(x) = 12 + 13 × 68 - 13 × 7
f(x) = 12 + 884 - 91
f(x) = 12 + 793
f(x) = 805

Find all the missing elements
Answer:
[tex] b = 5.5 [/tex]
[tex] c = 11.2 [/tex]
Step-by-step explanation:
Given:
A = 96°
B = 25°
C = 59°
a = 13
Required:
b and c
SOLUTION:
Use Sine Rule to find the measure of a and b, respectively.
✍️Thus, to find b, use,
[tex] \frac{a}{sin(A)} = \frac{b}{sin(B)} [/tex]
Plug in the values
[tex] \frac{13}{sin(96)} = \frac{b}{sin(25)} [/tex]
Multiply both sides by sin(25)
[tex] \frac{13}{sin(96)} \times sin(25) = \frac{b}{sin(25)} \times sin(25) [/tex]
[tex] \frac{13 \times sin(25)}{sin(96)} = b [/tex]
[tex] b = 5.5 [/tex] (nearest tenth)
✍️To find c, use,
[tex] \frac{a}{sin(A)} = \frac{c}{sin(C)} [/tex]
Plug in the values
[tex] \frac{13}{sin(96)} = \frac{c}{sin(59)} [/tex]
Multiply both sides by sin(59)
[tex] \frac{13}{sin(96)} \times sin(59) = \frac{c}{sin(25)} \times sin(59) [/tex]
[tex] \frac{13 \times sin(59)}{sin(96)} = c [/tex]
[tex] c = 11.2 [/tex] (nearest tenth)
General admission to Paul’s Pumpkin Patch is $8.00. For children to ride the various rides, they must use tickets that cost $1.00 each. The number of tickets needed for each ride varies. The function for this situation is P(x) = x + 8, where P(x) represents total cost as a function of the number of tickets, x. What is the domain for visiting and riding rides at Paul’s Pumpkin Patch?
A. P(x) ≥ $8.00
B. x is all real numbers
C. x ≥ 0, where x is non-negative
D. x ≥ 0, x is an integer
Given:
Total cost P(x) as a function of the number of tickets, x is
[tex]P(x)=x+8[/tex]
To find:
The domain for visiting and riding rides at Paul’s Pumpkin Patch.
Solution:
Domain is the set of input values.
Here, domain is x and it represents the number of tickets.
We know that, number of tickets cannot be negative or decimal or fraction vales. So, x must be non-negative and integer value.
Domain = x ≥ 0, x is an integer
Therefore, the correct option is D.

Answer:
x=-2/3,2
Step-by-step explanation:
Answer:
x = 6
Step-by-step explanation:
2 (3x - 2) - 4x + 1 = 9
Distribute the 2 to 3x and -2
6x - 4 - 4x + 1 = 9
Combine like terms
