To solve this, you need to isolate/get the variable "n" by itself in the equation:
-3(-4n + 30) = -30 Divide -3 on both sides
[tex]\frac{-3(-4n+30)}{-3} =\frac{-30}{-3}[/tex] [two negative signs cancel each other out and become positive]
-4n + 30 = 10 Subtract 30 on both sides
-4n + 30 - 30 = 10 - 30
-4n = -20 Divide -4 on both sides to get "n" by itself
[tex]\frac{-4n}{-4}=\frac{-20}{-4}[/tex]
n = 5
PROOF
-3(-4n + 30) = -30 Substitute/plug in 5 into "n"
-3(-4(5) + 30) = -30
-3(-20 + 30) = -30 Simplify what's inside the parentheses [PEMDAS}

At a basketball game, a team made 56 successful shots. They were a combination of 1- and 2-point shots. The team scored 95 points in all. Write and solve a system of equations to find the number of each type of shot.
To find the number of each type of shot, we can create a system of equations based on the given information and solve it. The equations are x + y = 56 and x + 2y = 95.
Explanation:To solve this problem, we can create a system of equations based on the given information. Let's assume that the team made x 1-point shots and y 2-point shots. We know that the team made 56 successful shots in total, so the first equation is x + y = 56. We also know that the team scored 95 points in total, and since each 1-point shot contributes 1 point and each 2-point shot contributes 2 points, the second equation is x + 2y = 95.
Now we can solve this system of equations:
x + y = 56
x + 2y = 95
By solving these equations, we can find the values of x and y, which represent the number of 1-point and 2-point shots respectively.

Team made 17 1-point shots and 39 2-point shots.
Let's define variables to set up the system of equations:
x: the number of 1-point shots
y: the number of 2-point shots
We know from the problem statement that:
The total number of shots is 56.
The total points scored is 95.
We can represent these conditions with the following system of equations:
Equation 1: x + y = 56
Equation 2: x + 2y = 95
Now, let's solve this system step-by-step:
Step 1: Solve Equation 1 for x:
x = 56 - y
Step 2: Substitute this expression into Equation 2:
56 - y + 2y = 95
Step 3: Simplify and solve for y:
56 + y = 95
y = 39
Step 4: Substitute y back into Equation 1 to find x:
x + 39 = 56
x = 17
Thus, the team made 17 1-point shots and 39 2-point shots.

Raman buys two packages of chicken wings. One package weighs 1.28 pounds, and the other weighs 2.63 pounds. The price of chicken wings is $3.25 per pound. What is the total cost of the chicken wings?
Total cost of the chicken wings is $12.71
Step-by-step explanation:
Step 1: Given weight of package 1 = 1.28 pounds, package 2 = 2.63 pounds and price of chicken wings per pound = $3.25Step 2: Calculate total weight of both packages = 1.28 + 2.63 = 3.91 poundsStep 3: Calculate total cost of chicken wings⇒ Total Cost = 3.91 × 3.25
⇒ Total cost = $12.71
Final answer:
To find the total cost of chicken wings, add the weights of both packages (1.28 pounds + 2.63 pounds = 3.91 pounds) and multiply by the price per pound ($3.25), yielding a total cost of $12.71.
Explanation:
The problem provided describes a scenario where Raman buys two packages of chicken wings weighing 1.28 pounds and 2.63 pounds. To calculate the total cost of the chicken wings at a price of $3.25 per pound, first, we need to determine the total weight of the chicken wings by adding the weight of both packages together. Next, we multiply the combined weight by the price per pound.
Here is the step-by-step calculation:
Add the weights of the two packages: 1.28 pounds + 2.63 pounds = 3.91 pounds.
Multiply the total weight by the price per pound: 3.91 pounds *$3.25 per pound.
Calculate the overall cost: 3.91 * $3.25 = $12.71.
Therefore, the total cost of the chicken wings is $12.71.

When the value of t is 60, the value of c is 90 . Explain what this means using the problem context.
Little help!!!!!
Answer:
Step-by-step explanation:
as the temp t increases the number of cricket chirps also increases.
1: The complete table is according to the given function :
t : 40 50 60 70 80 90 100
c : 10 50 90 130 170 210 250
2: It means when the temperature is 60 Fahrenheit then the number of cricket chirps is 90 per minute.
The given function is,
c = 4t - 180
Here t represents the temperature
c represents the cricket chirps per minutes
Now plug in each temperature value and solve for c:
When t = 40:
c = 4(40) - 150
c = 160 - 150
c = 10
When t = 50:
c = 4(50) - 150
c = 200 - 150
c = 50
When t = 60:
c = 4(60) - 150
c = 240 - 150
c = 90
When t = 70:
c = 4(70) - 150
c = 280 - 150
c = 130
When t = 80:
c = 4(80) - 150
c = 320 - 150
c = 170
When t = 90:
c = 4(90) - 150
c = 360 - 150
c = 210
When t = 100:
c = 4(100) - 150
c = 400 - 150
c = 250
Therefore, the complete table is:
t : 40 50 60 70 80 90 100
c : 10 50 90 130 170 210 250
When the value of t is 60, the value of c is 90.
It means when the temperature is 60 Fahrenheit then the number of cricket chirps is 90 per minute.

Chords NP and MQ intersect at point S in circle R.
If MS = 3, NS = 2, and SQ = 8, what is the length of SP?
Option C:
The length of SP is 12.
Solution:
In the given circle, NP and MQ are chords of the circle.
MS = 3, NS = 2, SQ = 8
To find the length of SP:
Segments of chords theorem:
If two chords intersects in the interior of a circle, then the product of the lengths of the segment of one chord is equal to the product of lengths of the segments of the other chord.
By this theorem,
NS × SP = MS × SQ
⇒ 2 × SP = 3 × 8
⇒ 2 SP = 24
Divide by 2 on both sides of the equation, we get
⇒ SP = 12
Option C is the correct answer.
The length of SP is 12.
Final answer:
Using the Intersecting Chord Theorem, we find that the length of SP is 3/4 by setting up the equation 3 * 2 = SP * 8 and solving for SP.
Explanation:
The student is asking about finding the length of a chord segment in a circle where two chords intersect. Since chords NP and MQ intersect at point S inside circle R, we can apply the Intersecting Chord Theorem.
This theorem states that the product of the lengths of the segments of one chord is equal to the product of the lengths of the segments of the other chord. In formula terms, MS × NS = PS × SQ.
We are given MS = 3, NS = 2, and SQ = 8. To find the length of SP, we just substitute into the theorem's formula: (3) × (2) = SP × (8). From this, we calculate that SP = 3/4, which is the length of the segment SP.

Express the following in scientific notation 77.31 × 10^4
The number 77.31 x 10^4 in scientific notation is 7.731 x 10 ^ 5. To achieve this, the decimal place was moved to the left and the power of 10 increased accordingly.
Explanation:To express the number 77.31 x 10^4 in scientific notation, we need to adjust it to fit the format 'a x 10^n', where 1 ≤ |a| < 10 and n is an integer. So, the main step is to transfer the decimal place in '77.31' to after the first digit, followed by multiplying by an appropriate power of 10.
Firstly, rewrite 77.31 as 7.731 by moving the decimal place one place to the left. Now, since our original number was multiplied by 10^4, this needs to be amended by 1 place for the movement of the decimal point. This results in 10^5, since you are now multiplying by 10 one more time than before.
Combining these, the given number is represented in scientific notation as 7.731 x 10 ^ 5.

You spend $288 on clothes. Shirts cost $24 and pants cost $32. you buy a total of 10 items
Answer:
I have bought 4 shirts and 6 pants.
Step-by-step explanation:
Let I have bought x number of shirts and y number of pants.
So, the two equation that we can write from the given conditions are
x + y = 10 ............. (1) and
24x + 32y = 288 ...... (2)
Now, solving equations (1) and (2) we get
24x + 32(10 - x) = 288
⇒ 8x = 320 - 288 = 32
⇒ x = 4
And y = (10 - 4) = 6
Therefore, I have bought 4 shirts and 6 pants. (Answer)
