2(2x+1)=x+5
4x+2=x+5
3x=3
x=1
Answer:
x=1
Step-by-step explanation:
2(2x + 1) = x + 5
Distribute
4x +2 = x+5
subtract 4 from each side
4x-x +2 = x-x+5
3x +2 = 5
Subtract 2 from each side
3x+2-2 = 5-2
3x = 3
Divide by 3
3x/3 = 3/3
x=1

Answer:
10 ^(R-15)/3 -2= a
Step-by-step explanation:
R = 3 log (a+2) +15
Subtract 15 from each side
R-15 = 3 log (a+2) +15-15
R-15 = 3 log (a+2)
Divide each side by 3
(R-15)/3 = 3/3 log (a+2)
(R-15)/3 = log (a+2)
The opposite of log is to raise each side to the power of 10
10 ^(R-15)/3 = 10 ^ log (a+2)
10 ^(R-15)/3 = (a+2)
Subtract 2 from each side
10 ^(R-15)/3 -2= (a+2-2)
10 ^(R-15)/3 -2= a
Answer:
10 ^(R-15)/3 -2= a

madison has a budget of $1,483 to spend this month. If she wants to split her money evenly over 4 weeks, how much can she spend each week
Answer:
370.75
Step-by-step explanation:
all you need to do is divide the original amount by 4
Final answer:
Madison can spend $370.75 each week if she divides her $1,483 monthly budget evenly over 4 weeks.
Explanation:
To find out how much Madison can spend each week, we divide her total monthly budget by the number of weeks in a month. Madison has a budget of $1,483 to spend this month. Since she wants to split her money evenly over 4 weeks, we perform the following calculation:
Total monthly budget: $1,483
Number of weeks in a month: 4
We divide the total budget by the number of weeks to find the weekly budget:
Weekly budget = Total monthly budget ÷ Number of weeks
Weekly budget = $1,483 ÷ 4
Weekly budget = $370.75
Therefore, Madison can spend $370.75 each week.

a 42.6 sq. yd
b. 36.3 sq yd
42.3 sq. yd
d. None of these
Please select the best answer from the choices provided
OA
pls give me brainliest :)
Answer:
B.) 36.3 sq. yd
Step-by-step explanation:
To find the area of a rectangle is l x w (length multiplied by width) The length of the rectangle is 6 yards and the width is 4.
6 x 4= 24
Now you need to find the area of a triangle. To find the bottom or base of the triangle you must subtract 6 from 9. (6 being the top of the rectangle and 9 being the base.) which should give you 3. Now that we have the base of the triangle we can find the area of the triangle using the formula which is b x h/ 2 (base multiplied by height divided by 2) b= 3 and h= 4. 3 x 4= 12 divided by 2 equals 6.
Last we need to find the area of the half circle, based off the side of the rectangle we can say the diameter of the circle is 4. The radius is half of the diameter 4/2 = 2. The formula to find the area of a circle is A= πr^2
π(2^2) = 12.57 and because its a half circle we divide it by 2 which equals 6.285
Now we add all the areas of each shape so, 24+6+6.285 which equals 36.3
Answer = B.) 36.3

The amount of money that Li spends on a video game depends on how many game he purchases. if Li has at most $90 to spend on games for his Xbox 360 and the games cost $22.50 each, what is the domain of this function?
_______________________
Answer:
Hence Domain set for function is {0,1,2,3,4}
Step-by-step explanation:
Given:
Total amount spend =90
22.5 $ each game cost
To Find:
What is domain for the function
Solution:
Now domain mean all possible value for input so that it gives real output as per condition mentioned
So Our condition is that li spends money on video game depends on how many game he purchases
so total money spent on game is output
i.e in order to get that much amount of games.
If he spends 22.5 $ for each game and Total amount spent is 90
So 90/22.5=4 Now amount of game he would purchase will be 4
i.e range for lil is 0 to 4 wiht 90 $ in hand
So Domain set will be ranging from{0,1,2,3,4}
Solve the system of equations shown by substitution. y=x-5 5x+2y=4
Answer:
x=2,y=-3
Step-by-step explanation:
y=x-5....(1)
5x+2y=4...(2)
Let's substitute (1) into (2)
5x+2(x-5)=4
5x+2x-10=4
7x-10=4
Add 10 to both sides
7x=14
Divide both sides by 7
x=2
Substitute the value for x into (1)
y=x-5
y=2-5
y=-3
Therefore x is 2,y is-3
Answer:
x = 2, y = -3
Step-by-step explanation:
y= x - 5
5x + 2y = 4
5x + 2(x - 5) = 4
5x + 2x - 10 = 4
7x = 14
x = 2
y = 2 - 5
y = -3

Takuya's parents gave him $100dollar as a birthday gift. Since he loves board games, he spent $20dollar out of his present on board games at the end of each month until his money ran out. Let f(n) be the amount of money that remained from Takuya's present during month n, where n=1 represents the month he received his present.
f is a sequence. What kind of sequence is it?
p.s" tell me if it is a geometric sequence or arithmetic and find the explicit formula
The amount of money that remained from Takuya's presence during month n is expressed as an=120-20n and the sequence is an arithmetic sequence.
What is an arithmetic sequence?The arithmetic sequence is the sequence where the common difference remains constant between any two successive terms. Let us recall what is a sequence. A sequence is a collection of numbers that follow a pattern. The general form of an arithmetic sequence is an=a+(n-1)d.
If Takuya's parents gave him $100 as a birthday gift and she spent $20 each month on board games until his money ran out, this means he keeps spending $20 every month and his money keeps reducing by the same amount each month until his money ran out, the following can be inferred;
initial amount = $100
If he spends $20 each month,
Balance at the end of 1st month = $100-$20 = $80
Balance at the end of 2nd month = $80-$20 = $60
Balance at the end of 3rd month = $60-$20 = $40 and so on
Since the amount keeps reducing by the same value i.e $20, then the sequence formed is an arithmetic sequence.
a is the first term of the sequence = 100
d is the common difference = 80-100 = 60-80 = 40-60 = -20
n is the number of terms
Substituting the given values in the formula we have; an=100+(n-1)(-20)
⇒an=100+(-20n+20)
⇒an=100-20n+20
⇒an=120-20n
Therefore, the amount of money that remained from Takuya's presence during month n is expressed as an=120-20n and the sequence is an arithmetic sequence.

1) Option (A) arithmetic sequence.
2) The recursive formula is f(n) = f(n-1) - 20 with an initial condition of f(1) = 100.
3) The explicit formula is f(n) = 120 - 20n.
Let's address Takuya's birthday gift scenario step by step.
1. Type of Sequence
The sequence described is an arithmetic sequence because the same amount of money, $20, is spent each month, leading to a consistent decrease in the balance.
2. Recursive Formula
Initially, he had $100. So,
f(1) = 100
Given the monthly spending of $20, the recursive formula is: f(n) = f(n-1) - 20
3. Explicit Formula
To find the explicit formula of the arithmetic sequence, we use the initial value and the common difference:
f(n) = 100 - 20(n-1)
Simplifying gives us:
f(n) = 120 - 20n
Thus, the balance remaining after n months can be calculated using this explicit formula.

Jonathon paid $237 for 15 pizzas, which included the $12 delivery charge. How much will he pay for 22 pizzas
Jonathon will pay $342 for 22 pizzas.
Initially, Jonathon paid $237 for 15 pizzas, which included the $12 delivery charge. To find the cost per pizza, we first subtract the delivery charge from the total amount.
Total without delivery charge = $237 - $12 = $225
Now, we divide this amount by the number of pizzas to find the cost per pizza.
Cost per pizza = $225 / 15 = $15
For 22 pizzas, we multiply the number of pizzas by the cost per pizza and then add the delivery charge.
Total cost for 22 pizzas = (22 x $15) + $12 delivery charge
= ($330) + $12
= $342
Therefore, Jonathon will pay $342 for 22 pizzas.

The area of a rectangular rug is given by the trinomial r^2-4r-21. What are the possible dimensions of the rug?
Answer:
There are two possible values for r (area): r =-7 or r=3
Step-by-step explanation:
Given the rectangular rug area is:
[tex]r^{2} -4r -21[/tex]
We have to convert the above equation into factored form.
So two numbers whose product is -21r² and sum is -4r
<=> [tex]r^{2} -4r -21[/tex]
= [tex]r^{2} -7r + 3r -21[/tex]
= r (r -7) + 3(r -7)
= (r-7)(r+3)
We set [tex]r^{2} -4r -21[/tex] = 0
<=> (r-7)(r+3) = 0
<=> (r-7) = 0 or (r+3) = 0
<=> r =-7 or r=3
So, there are two possible values for r (area): r =-7 or r=3
Final answer:
The possible dimensions of the rectangular rug with the given area trinomial r²-4r-21 are 7 by 3 or 3 by 7.
Explanation:
The possible dimensions of the rectangular rug with area given by the trinomial r²-4r-21 can be found by factoring the trinomial.
Factoring r²-4r-21 results in (r-7)(r+3). Therefore, the dimensions could be 7 by 3 or 3 by 7.

Given:
[tex]\angle A=5 x-18^{\circ}[/tex]
[tex]\angle B=3 x+42^{\circ}[/tex]
To find:
The value of x and measure of angle A
Solution:
Alternate interior angle theorem:
If two parallel lines cut by a transversal, then the alternate interior angles are congruent.
⇒ m∠A = m∠B
[tex]5x-18^\circ=3x+42^\circ[/tex]
Add 18° on both sides.
[tex]5x-18^\circ+18^\circ=3x+42^\circ+18^\circ[/tex]
[tex]5x=3x+60^\circ[/tex]
Subtract 3x from both sides.
[tex]5x-3x=3x+60^\circ-3x[/tex]
[tex]2x=60^\circ[/tex]
Divide by 2 on both sides.
⇒ x = 30°
Substitute x = 30° in ∠A.
m∠A = 5x - 18°
= 5(30°) - 18°
= 150° - 18°
= 132°
The measure of ∠A is 132°.
