Your school club has a bake sale to raise money. Your club offers muffins for $.50 each and bagels for $.75 each. In one hour you raise $21 by selling 34 items. How many muffins did you sell?
Answer:
18 muffins
Step-by-step explanation:
From the information given, you can write the following equations:
x+y=34 (1)
0.50x+0.75y=21 (2)
where x is the number of muffins and y is the number of bagels.
First, you can isolate x in (1):
x=34-y (3)
Then, you can replace (3) in (2):
0.50(34-y)+0.75y=21
17-0.5y+0.75y=21
0.25y=21-17
0.25y=4
y=4/0.25
y=16
Now you can replace the value of "y" in (3):
x=34-16
x=18
According to this, the answer is that you sold 18 muffins.
Question one, how do you solve this? "A, B, and C are collinear. Find AC if AB = 12 and BC = 8"
Question two, can anyone solve these two problems i attached? They use Segment Addition and Angle Addition Postulates.
Answer:
20''Step-by-step explanation:
If points A, B and C are collinear, then A, B and C lies on the same straight line. Hence AB+BC = AC
Given
AB = 12''
BC = 8''
To get length od segment AC, we will substitute the given values into the formula above as shown;
AB+BC = AC
12 + 8 =AC
AC = 12+ 8
AC = 20''
Hence the length of AC is 20''

Solve the simultaneous equation.......2x + 10y = 50 (equation 1) and 1.5x + 25y = 90 (equation 2)
Step-by-step explanation:
2x + 10y = 50 ... 1
1.5x + 25y = 90 ...2
...1 × 2.5
5x + 25y = 125 ...3
...3 - ...2
3.5x = 35
x = 10
replaced x = 10 in ...1
2(10) + 10y = 50
20 + 10y = 50
10y = 50 - 20
10y = 30

Whose do you agree with, and why?
Answer:
Kyra is correct.
Step-by-step explanation:
Rational numbers;
All numbers which can be written in the form of [tex]\frac{p}{q}[/tex] are rational numbers.
Example: 1, 2, [tex]\frac{1}{2}[/tex], 1.414141....
Irrational numbers:
Numbers which are not in the form of [tex]\frac{p}{q}[/tex] are irrational.
Example: 1.234, π, √2
So rational and irrational numbers are two separate things.
But all positive and negative numbers are real numbers.
Real numbers may be rational or irrational both.
Therefore, Kyra's interpretation is correct.

if <1 and <2 are supplementary angles, m<1=4x° and m<2=8x° then whats the measures of 1 and 2
Answer:
angle 1 = 60 degrees
angle 2 = 120 degrees
=====================================================
Explanation:
Supplementary angles always add to 180 degrees. In other words, the two angles form a straight line.
(angle1) + (angle2) = 180
4x+8x = 180
12x = 180
12x/12 = 180/12 .... dividing both sides by 12
x = 15
Use this x value to find the two angle measures
angle1 = 4x = 4*15 = 60
angle2 = 8x = 8*15 = 120
As a check, angle1+angle2 = 60+120 = 180, which confirms our answer.

The first term of an arithmetic sequence is -2. The eighth term of the sequence is 26. What is the common difference of the arithmetic sequence?
Answer:
d = 4
Step-by-step explanation:
The n th term of an arithmetic sequence is
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Given a₁ = - 2 and a₈ = 26 , then
- 2 + 7d = 26 ( add 2 to both sides (
7d = 28 ( divide both sides by 7 )
d = 4
Answer:
d = 4
Step-by-step explanation:
a₁ = -2
a₈ = aₙ = 26
n = 8
aₙ = a₁ + d(n-1)
d = aₙ - a₁ / (n-1)
d = 26 -(-2) / (8-1)
d = 26 + 2 / 7
d = 28 / 7
d = 4
-2
-2 + 4 = 2
2 + 4 = 6
6 + 4 = 10
10 + 4 = 14
14 + 4 = 18
18 + 4 = 22
22 + 4 = 26

The polynomial x^2 - 22x + 121 represents the area (in square feet) of a square courtyard. a.) write a polynomial that represents the side length of the courtyard.
b.) Write an expression for the perimeter of the courtyard.
Answer:
Step-by-step explanation:
Since the court yard is square in nature, the area of the court yard will be exprerssed as;
A = Length * Length
A(x) = L²
Given area of the court yard A(x) = x^2 - 22x + 121
x^2 - 22x + 121= L²
Factorizing the quadratic expression
(x^2 - 11x) -(11x+ 121) = L²
x(x-11)-11(x-11) = L²
(x-11)(x-11) = L²
(x-11)² = L²
Square root both sides to the length of the courtyard
√(x-11)² = √L²
L = x-11
Hence the length of the courtyard is (x-11)ft
b) The perimeter of the courtyard P = 4L
P = 4(x-11)
P = 4x - 44
Hence an expression for the perimeter of the courtyard is 4x-44 feet

[tex]-\frac{-32-\left(-16\right)}{8}=2\\x=2\\x=2,\:y=-16[/tex]
Answer:
x = 2
y = -16
Step-by-step explanation:
Substitute value of y, -3x - 10 in the equation-8x + y = -32
-8x + (-3x - 10) = -32
-8x - 3x - 10 = -32
-11x - 10 = -32
-11x = -32 + 10
-11x = -22
Divide both sides by coefficient of x which is -11
x = 2
Substitute value of x, 2, in the equation-3x - 10 = y
(-3)2 - 10 = y
-6 - 10 = y
y = -16

Which statement describes the symmetry of j(x)?
j(x) is an odd function.
j(x) is an even function.
j(x) is both an even and an odd function.
j(x) is neither an even nor an odd function.
Answer:
j(x) is an odd function
Step-by-step explanation:
We are given;
j(x) = 220/x³ and j(-x) = 220/(-x)³
Now,
when x = 1;
j(x) = 220/1³ = 220/1 = 220
j(-x) = 220/(-1)³ = 220/-1 = -220
When x = 2;
j(2) = 220/2³ = 220/8
j(-2) = 220/(-2)³ = -220/8
Now, Algebraically, function j would be even if and only if j(-x) = j(x) for all x in the domain of j. While j is odd if and only if j(-x) = -j(x) for all x in the domain of j.
From the values gotten, we can see that :j(-x) = -j(x). Thus, we can say that j(x) is an odd function.
Answer:
A) j(x) is an odd function.

the measure of the supplement angle is 24 more than three time the measure of the original angle. find the measures of the angles.
Step-by-step explanation:
Let x° be the original angle. Then the supplement angle is (180 - x)° and (180 - x) = 3x + 24.
180 - x = 3x + 24
4x = 156
x = 39
Hence the original angle is 39° and the supplementary angle is 141°.
The angles are 39° and 141°.
What is a complementary angle ?Two angles are said to be complementary to each other when their sum is 90°
According to the given question
The measure of the supplement angle is 24 more than the measure of the original angle.
Let the original angle be x
So from the given data it's supplement angle is 3x + 24.
We know two angles are supplementary when their sum is 180°.
∴ x + 3x + 24° = 180°
4x = 156°
x = (156/4)°
x = 39°.
So, the original angle is 39° and it's supplementary angle is 141°.
