Explanation:
There's a quick way to answering questions like this without the need to go through the whole process of finding the terms before the
x
3
term:
Using the
n
C
r
button, the value of
n
represents the expansion power of
9
and the
r
would be the term you want to find, so in this case, it would be
3
.
Therefore, the coefficient of the general
x
3
term is:
9
C
3
=
84
However, you can only do this if the expansion is in the format of
(

+
x
)
n
.
To find the

y = 4x+1
3x + 2y = 13
Answer:
x=1 y=5
Step-by-step explanation:
plug y = 4x+1 into the second equation, so
3x+2(4x+1)=13 and solve
3x+8x+2=13
11x+2=13
11x+2-2=13-2
11x=11
x=1
then plug x=1 into the first equation

The total interest on a 5 year 5.2% loan with a principal of $10,000 is 10,000 × 0.052 × 5 = $2,600.
True or False?
Answer:
True
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 5.2%/100 = 0.052 per year,
then, solving our equation
I = 10000 × 0.052 × 5 = 2600
I = $ 2,600.00
The simple interest accumulated
on a principal of $ 10,000.00
at a rate of 5.2% per year
for 5 years is $ 2,600.00.

Answer:
20 is the anwser for this problem
The number of medium bags will be 410 / 3.
What are ratios and proportions?An ordered pair of numbers a and b, represented as a / b, is a ratio if b is not equal to 0. A proportion is an equation that sets two ratios at the same value. The numerical relationship between two values demonstrates how frequently one value contains or is contained within another.
Given that Jill puts 440 sweets into small bags, medium bags and large bags. She uses 30 small bags
The equation can be written as,
L + M + S = 440
L = 2M
2M + M + 30 = 440
3M = 410
M = 410 / 3
Therefore, the number of medium bags will be 410 / 3.

Write a System of Equations to solve the following problem:
The school that Maria goes to is selling tickets to the annual talent show. On the first day of ticket sales the school sold 1 senior citizen ticket and 12 student tickets for a total of $51. The school took in $93 on the second day by selling 5 senior citizen tickets and 6 student tickets. What is the price each of one senior citizen ticket and one student ticket?
Cost of Senior Citizen Ticket: $
Cost of Student Ticket: $
Answer:
Cost of Senior Citizen Ticket: $15
Cost of Student Ticket: $3
Step-by-step explanation:
Let the price of a senior citizen ticket be s.
Let the price of a student ticket be t.
Day 1:
s + 12t = 51
Day 2:
5s + 6t = 93
The system of equations is:
s + 12t = 51
5s + 6t = 93
Let's use the substitution method to solve it. Solve the first equation for s.
s = 51 - 12t
Now substitute s in the second equation with 51 - 12t.
5s + 6t = 93
5(51 - 12t) + 6t = 93
255 - 60t + 6t = 93
Subtract 255 from both sides. Combine -60t and 6t.
-54t = -162
Divide both sides by -54.
t = 3
Now substitute 3 for t in the equation
s = 51 - 12t
s = 51 - 12(3)
s = 51 - 36
s = 15
Answer:
Cost of Senior Citizen Ticket: $15
Cost of Student Ticket: $3

May someone please help me out? Just do 1 and I just need steps because I’m unfamiliar with this.
Answer:
x=5.09
Step-by-step explanation:
Always look at what info they give you, here you have angle, opposite, and adjacent. The trig function that uses [tex]\frac{opp}{adj}[/tex] is tangent so tan (27) = [tex]\frac{x}{10}[/tex] so
x = 10 tan (27) so x = 10 (.5095254495) [make sure you are in degree mode] so x has to be 5.09
The same goes for question 10, check what you are given [hint: you will need sin probably]....good luck!

An angle measures 38° less than the measure of its complementary angle. What is the measure of each angle?
Answer:
One angle is 26 degrees and the other is 64 degrees.
Step-by-step explanation:
Complementary angles add up to a total of 90 degrees. Therefore, if one of the two angles is known to be 38 degrees less, then the other angle can be calculated:
90 = (x-38) + (x)
52 = 2x
26 = x
This means that one of the angles is 26 degrees, and the other is 64 degrees.

The angles x°, 2x°, and (x + 10)° are complementary angles. Then the value of the variable x will be 20°.
What is an angle?The angle is the distance between the intersecting lines or surfaces. The angle is also expressed in degrees. The angle is 360 degrees for one complete spin.
Complementary angle - Two angles are said to be complementary angles if their sum is 90 degrees.
The angles x°, 2x°, and (x + 10)° are complementary angles.
Then the sum of the angles x°, 2x°, and (x + 10)° will be 90°.
Then the equation will be
x° + 2x° + (x + 10)° = 90°
Simplify the equation, then the value of x will be
4x + 10 = 90
4x = 80
x = 20°
Thus, the value of the variable x will be 20°.
