Answer: x=45
Step-by-step explanation:
Solve for c get 20 c=b so b+115 =135 180-135=x
Answer:
x=45
Step-by-step explanation:
160=115+x (use vertical angles)
subtract 115 from both sides
160-115=45
x=45

B. y - 1 = 3(x-13)
C. y - 2 = 3(x - 4)
D. y - 4 = 3(x+2)
Answer:
D. y - 4 = 3 (x + 2)

Answer:
C. x = 3
Step-by-step explanation:
8x - 8 = 2x + 10
get the x on it's own
8x - 8 + 8 = 8x
2x + 10 + 8 = 2x + 18
8x = 2x + 18
8x - 2x = 6x
2x + 18 - 2x = 18
6x = 18
now divide each side by 6
6x / 6 = x
18 / 6 = 3
x = 3
X=3
Explanation
8x-8=2x+10
6x=18
x=3

Two playful kittens working together can unwind all the balls of yarn in a basket 9
minutes faster than if the first kitten is working alone, and 4 minutes faster than if the
second kitten is working alone. How long does it take each kitten to unwind all the
balls of yarn alone?
Answer:
The time it takes the first kitten to unwind the balls of yarn alone is 15 minutes
The time it takes the second kitten to unwind the balls of yarn alone is 10 minutes
Step-by-step explanation:
The time it takes the two kitten to unwind the balls of yarn = 9 minutes faster than the first kitten working alone
The time it takes the two kitten to unwind the balls of yarn = 4 minutes faster than the second kitten working alone
Let 'x' represent the time it takes the first kitten to unwind the balls of yarn alone, let 'y' represent the time it takes the second kitten to unwind the balls of yarn alone, and let 't' represent the time it takes the two kitten to unwind the balls of yarn we have;
x = t + 9
y = t + 4
The rate of working, per ball of yarn, of the first kitten = 1/x = 1/(t + 9)
The rate of working, per ball of yarn, of the second kitten = 1/y = 1/(t + 4)
The amount of work each kitten does in the time 't', added together to unwind 1 ball of yarn is given as follows;
t/(t + 9) + t/(t + 4) = 1
(t·(t +4) + t·(t + 9))/(t + 4)×(t + 9) = 1
Using a graphing calculator, we have;
(2·t²+13·t)/(t² + 13·t + 36) = 1
∴ (2·t² + 13·t) = (t² + 13·t + 36)
(2·t² + 13·t) - (t² + 13·t + 36) = 0
t² - 36 = 0
t = √36 = 6
t = 6
x = t + 9 = 6 + 9 = 15
The time it takes the first kitten to unwind the balls of yarn alone, x = 15 minutes
y = t + 4 = 6 + 4 = 10
The time it takes the second kitten to unwind the balls of yarn alone, y = 10 minutes

Answer:
6 is composite
Step-by-step explanation:
Given

Required
Prime or Composite
The number 6 is not prime. This is so because apart from 1 and 6, it can also be divided by 2, 3
Hence:
6 is composite

1, 2, 3 and 6
Triangle TRS is similar to triangle TMN. Angle T = 40°, angle R = 60°, and angle S = 80° . What is the measure of angle M
Answer:
60degrees
Step-by-step explanation:
For similar triangles, the angles of their angles are equal to matter the size.
Hence if triangle TRS is similar to triangle TMN, then;
<R = <M and <S = <N
Given that;
<T = 40 degrees
<R = 60degrees
<S = 80 degrees
Since <R = <M, then <M = 60degrees
Expand and simplify (x + 5)(x - 2)
Answer: *x squred +3x-10*
Step-by-step explanation:
(x+5)(x-2)
x squred-2x+5x-10
x squred +3x-10
The equation ( x + 5 ) ( x - 2 ) can be simplified as x² + 3x - 10
What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be = A
Now , the equation A = ( x + 5 ) ( x - 2 )
On simplifying the equation , we get
A = x ( x - 2 ) + 5 ( x - 2 )
Expanding the brackets , we get
A = x² - 2x + 5x - 10
On simplifying the equation , we get
A = x² + 3x - 10
Therefore , the value of A is x² + 3x - 10
Hence , The equation ( x + 5 ) ( x - 2 ) can be simplified as x² + 3x - 10

2) UPS charges $7 for the first pound, and $0.20 for each additional pound. FedEx charges $5 for the first pound, and $0.30 for each additional pound. How many pounds, p, will it take for UPS and FedEx to cost the same?
Answer:
Step-by-step explanation:
300×1.035⁵ ≅ $356.31
:::::
UPS charge = 7 + (p-1)0.20 = 0.20p +6.80
FedEx charge = 5 + (p-1)0.30 = 0.30p + 4.70
0.30p + 4.70 = 0.20p +6.80
0.10p = 2.1
p = 21
They charge the same for 21 pounds.

blanket, or other sentimental object, according to a survey of a random
sample of 100 adults. A similar study, based on a random sample of 80

The sum of five consecutive multiples of 4 is 20.Find the smallest integer.
Answer:
The smallest integer is -4.
Step-by-step explanation:
Let the smallest integer be x.
Since the integers are all multiples of 4, they are
=> x, x+4, x+8, x+12 and x+16
=> x + x+4 + x+8 + x+12 + x+16 = 20
=> 5x + 40 = 20
Subtract 40 from both sides of the equation
5x +40 - 40 = 20 - 40
5x = -20
Divide both sides by the coefficient of x(which is 5)
[tex]\frac{5x}{5} = \frac{-20}{5}[/tex]
x = -4
∴ the smallest integer is -4.
