Jose can use the rule m(x)=10+3x to find m(x) , the amount of money he will have after a week of doing x additional hours of chores. Evaluate m(20), What does this mean?
Answer:
70
Step-by-step explanation:
Given:
m(x) = 10 + 3x
where,
m(x) = the amount of money he will have after a week of doing x additional hours of chores
x = additional hours of chores
Evaluate m(20), What does this mean?
m(x) = 10 + 3x
m(20) = 10 + 3(20)
= 10 + 60
= 70
m(20) = 70
m(20) means additional hours of chores is 20

Camilla bought a book that was on sale for 25% off the retail price. The retail price of the book was $12. What was the price Camilla paid for the book?
Answer:
The price that Camilla paid for the book was $9.
Step-by-step explanation:
To be able to find the pice that Camilla paid for the book, first, you have to calculate the 25% of the price of the book:
$12*25%=$3
Now, you have to subtract that amount from the price of the book:
$12-$3=$9
According to this, the answer is that the price that Camilla paid for the book was $9.

mr cadwell wants to purchase a motorcycle. he has financing options a and b to chose from, as shown below.
Option A-
Down Payment: $1,000
Monthly payment for 3 years: $85
Option B-
Down payment: $1,200
Monthly Payment for 3 years: $85
The purchase of the motorcycle is $3,500, including tax. Based on the info provided in the table, which statement is true?
Option B is better
Option A is better
Answer:
Option A is better.
Step-by-step explanation:
We will observe both plans one by one to determine which one is better i.e. which one will has less interest to pay.
So,
Option A:
Down Payment: $1,000
Monthly payment for 3 years: $85
The total amount in installments will be:
[tex]=Amount\ per\ month * months\\= 85*36\\=3060[/tex]
The total price of bike will be:
[tex]Total\ price = Downpayment +Installments\\= 1000+3060\\= 4060\\Interest = Total\ price - Purchase \\= 4060-3500\\=560[/tex]
Option B:
Down Payment: $1,200
Monthly payment for 3 years: $85
The total amount in installments will be:
[tex]=Amount\ per\ month * months\\= 85*36\\=3060[/tex]
The total price of bike will be:
[tex]Total\ price = Downpayment +Installments\\= 1200+3060\\= 4260\\Interest = Total\ price - Purchase \\= 4260-3500\\=760[/tex]
We can see that interest in Option A is less than interest in Option B that means Mr. Cardwell will have to pay less amount in Option A.
Hence,
Option A is better.
Solve each equation. For each step. Identify the property used.
14 + 3n = 8n - 3(n-3)
22x + 11 = 4x - 7
(P.S. The properties that the problem is asking for are the properties of equality. Division property of equality, etc, etc.)
Answer:
Solution of [tex]14 + 3n = 8n - 3(n-3)[/tex] => x = 5/2
Solution of [tex]22x + 11 = 4x - 7[/tex] => x=-1
Step-by-step explanation:
We will solve the equations one by one
So,
[tex]14 + 3n = 8n - 3(n-3)[/tex]
Applying Distributive property
[tex]14 + 3n = 8n - 3n+9\\14+3n = 5n+9[/tex]
Subtraction property of equality (Subtracting 14 from both sides)
[tex]14+3n-14 = 5n+9-14\\3n = 5n-5[/tex]
Subtraction property of equality (Subtracting 5n from both sides)
[tex]3n-5n = 5n-5-5n\\-2n = -5[/tex]
Division property of equality (Dividing both sides by -2)
[tex]\frac{-2n}{-2} = \frac{-5}{-2}\\n = \frac{5}{2}[/tex]
Second Equation:
[tex]22x + 11 = 4x - 7[/tex]
Subtraction property of equality (Subtracting 11 from both sides)
[tex]22x + 11-11 = 4x - 7-11\\22x = 4x-18[/tex]
Subtraction property of equality (Subtracting 4x from both sides)
[tex]22x-4x = 4x-18-4x\\18x = -18[/tex]
Division property of equality (Dividing both sides by 18)
[tex]\frac{18x}{18} = \frac{-18}{18}\\x = -1[/tex]
Hence
Solution of [tex]14 + 3n = 8n - 3(n-3)[/tex] => x = 5/2
Solution of [tex]22x + 11 = 4x - 7[/tex] => x=-1

Which of these equations, when solved, gives a different value of x than the other three?
9.1 = -0.2x + 10
10 = 9.1 + 0.2x
10 – 0.2x = 9.1
9.1 – 10 = 0.2x
Answer: 9.1-10=0.2x
Step-by-step explanation:
9.1 = −0.2x + 10
−0.2x + 10 = 9.1
−0.2x + 10 − 10 = 9.1 −10
−0.2x = −0.9
−0.2x / −0.2 = −0.9 / −0.2
x=4.5
10 = 9.1 + 0.2x
10 = 0.2x + 9.1
0.2x + 9.1 = 10
0.2x + 9.1 − 9.1 = 10 − 9.1
0.2x = 0.9
0.2x / 0.2 = 0.9 / 0.2
x=4.5
10 − 0.2x = 9.1
10 + (−0.2x) = 9.1
−0.2x + 10 = 9.1
−0.2x + 10 − 10 = 9.1 − 10
−0.2x = −0.9
−0.2x / −0.2 = −0.9 / −0.2
x=4.5
9.1 - 10 = 0.2x
-0.9 = 0.2x
-0.9 / 0.2 = 0.2x / 0.2
x= -4.5
Answer:
the answer is d/9.1 – 10 = 0.2x

Ordena de forma creciente los siguientes números enteros, colocando el signo de desigualdad mayor (>) o menor (<) correspondiente entre ellos a) 32 ; −2 ; −11 ; 6 ; −7 ; 20 ; −21 ; −32 ; 30 ; −16
Answer:
El orden de forma creciente de los números enteros es:
-32< -21< -16< -11< -7< -2< < 6< 20< 30< 32
Step-by-step explanation:
Ordenar de forma creciente números enteros implica ordenarlos de menor a mayor. Esto es, debes considerar primero el número que posea el menor valor y luego ir ordenándolos a medida que su valor vaya aumentando, para dejar en último lugar al que posea el mayor valor.
Para ordenarlos debes tener en cuenta que:
todo número negativo es menor que cero, mientras que todo número positivo es mayor que cero. de dos enteros negativos es mayor el que tiene menor valor absoluto. de los enteros positivos, es mayor el que tiene mayor valor absoluto.Entonces, en este caso el orden de forma creciente de los números enteros es:
-32< -21< -16< -11< -7< -2< < 6< 20< 30< 32
What is the measure of angle x?
A) 65
B) 25
C) 115
D) 125
Answer: 65°
Step-by-step explanation: We are assuming that these lines are ║.
If two parallel lines are cut by a transversal,
then alternate interior angles are congruent.
Since x and 65 lie on alternate side of the transversal and
on the interior of the two lines, we know that x = 65.

Use the figure to find the measure of angle 2.
Answer:
∠ 2 = 70°
Step-by-step explanation:
110° and ∠ 1 are corresponding angles and congruent, thus
∠ 1 = 110°
∠ 1 and ∠ 2 are adjacent angles and are supplementary, thus
∠ 2 = 180° - ∠ 1 = 180° - 110° = 70°

Find the slope and y-intercept of the line in each graph.
PLEASE HELP ASAP
Answer:
slope m = -2, y-intercept b = 1
Step-by-step explanation:
The slope is the change in y over the change in x.
Equation for slope: y2-y1/x2-x1=m
Since they already gave us the two points we just have to decide which one is our y2,y1 and out x2,x1 (which one you chose does not matter). And plug the numbers into the equation and get: -3-1/2-0=m, in this case, m=-4/2 and simplify it into -2. Now we have our slope.
The y-intercept is where the line crosses over the y-axis, and in our case, it is given to us in the (0,1) so our slope is 1.
