Answer: C. 75
Concept:
Here, we need to know the idea of quadrilaterals in a circle.
The opposite angles of quadrilaterals in a circle (cyclic quadrilaterals) are supplementary, meaning they add up to 180°
If you are still confused, please refer to the attachment below for a graphical explanation.
Solve:
Given information
The opposite angle of b = 105°
Given expression
b + opposite angle of b = 180°
Substitute values into the expression
b + 105 = 180
Subtract 105 on both sides
b + 105 - 105 = 180 - 105
b = 75°
Hope this helps!! :)

Find (f - g) (x)
f(x) = 2x^2 – 2 and g(x) = 4x + 1
6x2
Answer:
(f - g) (x) = 2x^2 - 4x - 3
Step-by-step explanation:
(f - g) (x) = f(x) - g(x)
(f - g) (x) = 2x^2 - 2 - (4x + 1)
(f - g) (x) = 2x^2 - 2 - 4x - 1
(f - g) (x) = 2x^2 - 4x - 3

A bag of sweets contains mints and toffees only.There are 21 mints in the bag.One quarter of the sweets are toffees.Calculate the total number of sweets in the bag.
Answer:
Total number of sweets in the bag is 28
Step-by-step explanation:
let the total number of sweets in the bag be x :
[tex]{ \tt{for \: toffees : }} \\ \frac{1}{4} \: of \: x[/tex]
therefore fraction of mints = 1 - fraction of toffees :
[tex] = \frac{4}{4} - \frac{1}{4} \\ \\ = \frac{3}{4} [/tex]
therefore:
[tex] = > \frac{3}{4} \: of \: x = 21 \: mints \\ \\ \frac{3}{4} \times x = 21 \\ 3x = 21 \times 4 \\ x = \frac{21 \times 4}{3} \\ x = 28[/tex]
total sweets number is 28

Convert 8x - 6y + 12 = 0 into Slope-Intercept Form.
Answer:
y = [tex]\frac{4}{3}[/tex] x + 2
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Given
8x - 6y + 12 = 0 ( subtract 8x + 12 from both sides )
- 6y = - 8x - 12 ( divide terms by - 6
y = [tex]\frac{-8}{-6}[/tex] x + 2 , that is
y = [tex]\frac{4}{3}[/tex] x + 2 ← in slope- intercept form
The GCF of two numbers is 3.
Their LCM of the two numbers is less than 20.
Which could not be the two numbers?
Answer:
Step-by-step explanation:

Simplify 0.2(4.9x + 6) + 0.8(2 - 3x)
The simplified expression is -1.42x + 2.8.
How to Simplify 0.2(4.9x + 6) + 0.8(2 - 3x)Sure, let's simplify the expression step by step:
1. Distribute the coefficients to the terms inside the parentheses:
0.2 * 4.9x + 0.2 * 6 + 0.8 * 2 - 0.8 * 3x
2. Simplify each term:
0.98x + 1.2 + 1.6 - 2.4x
3. Combine like terms:
(0.98x - 2.4x) + (1.2 + 1.6)
-1.42x + 2.8
So, the simplified expression is -1.42x + 2.8.

here is a sequence of number 7, 5 ,3 ,1, - 1 find the next term in the sequence
Answer:
-3
Step-by-step explanation:
in every term we subtract 2 so
7-2=5
so in every answer subtract 2
5-2=3
3-2=1
1-2=-1
-1-2=-3
Answer:
- 3
Step-by-step explanation:
There is a common difference between consecutive terms in the sequence, that is
5 - 7 = 3 - 5 = 1 - 3 = - 1 - 1 = - 2
Thus subtracting 2 from the last term shown gives the next term
- 1 - 2 = - 3

Answer:
c = 1
Step-by-step explanation:
Given
9 = 2(c + 3) + 1 ← distribute parenthesis and simplify right side

Step-by-step explanation:
a square + 7 a + 12 =A + 4
Step-by-step explanation:
[tex] {a}^{2} + 7a + 12 = a + 4 \\ {a}^{2} + 7a - a - 4 + 12 = 0 \\ {a}^{2} + 6a + 8 = 0 \\ {a}^{2} + 4a + 2a + 8 = 0 \\ a(a + 4) + 2(a + 4) = 0 \\ (a + 4)(a + 2) = 0 \\ a + 4 = 0 \: or \: a + 2 = 0 \\ a = - 4 \: or \: a = - 2[/tex]
Answer:
a = -4 or a = -2
Step-by-step explanation:
a² + 7a + 12 = a + 4
=> a² + 7a - a + 12 - 4 = 0
=> a² + 6a + 8 = 0
=> a² + 2a + 4a + 8 = 0
=> a(a + 2) + 4(a + 2) = 0
=> (a + 4)(a + 2) = 0
=> a = -4 or a = -2
the larger of 2 numbers is twice the smaller number if 12 is subtracted from the larger number the result is 7 more than the smaller number
Answer:
The larger number is 4
Step-by-step explanation:
4 is the larger number and two is the smaller number..
Answer:
x=19y=38Step-by-step explanation:
Let x be the smaller number
Let y be the larger number
The larger of 2 numbers is twice the smaller number :
[tex]y = 2x[/tex]
if 12 is subtracted from the larger number the result is 7 more than the smaller number :
[tex]y-12 = 7+x[/tex]
To solve for x ;
Substitute 2x for y in the second equation
[tex]2x-12=7+x\\2x-x=7+12\\x = 19[/tex]
To solve for y
[tex]If\: y=2x ,\\y = 2\times 19\\\\y= 38[/tex]

Hey! Please help i will give brainlest!!·
Answer:
7⅔ pounds to be shared 1⅓ per container.
For a clearer and swift understanding
Change them from Mixed NUMBERS to simple fractions
7⅔ = 23/3
1⅓ = 4/3
Now
We need to Fill 23/3 pounds of walnuts by 4/3 each into a container
Simply divide 23/3 by 4/3 to know how many walnuts that would enter
23/3 ÷ 4/3
23/3 x 3/4 = 23/4.
SO 23/4 CONTAINERS WOULD BE FILLED.
23/4 containers when converted to mixed numbers is
5¾.
This is our answer.
But Looking at the Question
5¾ has been broken to two fractions.
The Number that'll fill the blank space is 5.
Why? 5 + 9/12 = 23/4 which is the answer we got initially.
ANSWER = 5
Hope it helps tho.
