f x is a prime number, then x + 1 is not a prime number.
A counterexample is x =
Answer:
x=2
Step-by-step explanation:
x=2
x+1=3
and 3 is a prime
Answer:
A counterexample is x = 3
Step-by-step explanation:
We are given that x is a prime number, and x + 1 is not a prime number. However consider the number 3. We know that 3 is a prime number, as it is present as factors of 1 and itself. However 3 + 1 = 4 - which falls into the category of a composite number, as it can divide into 2 * 2. Therefore your counterexample could be x = 3.

Find the value of x. A. 15 B. 28 C. 20 D. 40
Answer:
A. 15
Step-by-step explanation:
When a tangent and a secant, two secants, or two tangents intersect outside a circle then the measure of the angle formed is one-half the positive difference of the measures of the intercepted arcs.
Hence,
(2x + 15)° = 1/2[(10x + 20)° - 80°]
2(2x + 15)° = (10x - 60)°
4x + 30 = 10x - 60
60 + 30 = 10x - 4x
90 = 6x
90/6 = x
15 = x
x = 15

A pair of supplementary angles in ratio of 4:5.find them here
Answer:
one angle 100
another angle=80
Step-by-step explanation:
supplementary angles =180
4x+5x=180
9x=180
x=180/9=20
one angle=5x=5(20)=100
another angle=4x=4(20)=80
100+80=180
Answer:
[tex] \boxed{ \boxed{ \bold{ \purple{80 \: , 100}}}}[/tex]Step-by-step explanation:
Let the ratios be 4x and 5x
[tex] \sf4x + 5x = 180[/tex] ( sum of supplementary angle )
Collect like terms
⇒[tex] \sf{9x = 180}[/tex]
Divide both sides of the equation by 9
⇒[tex] \sf\frac{9x}{9} = \frac{180}{9} [/tex]
Calculate
⇒[tex] \sf{x = 20}[/tex]
Value of x = 20
Now, let's replace the value,
⇒[tex] \sf4x = 4 \times 20 = 80[/tex]
⇒[tex] \sf5x = 5 \times 20 = 100[/tex]
Hope I helped!

Solve for q 3(q+4/3)=2
Answer:
q = - [tex]\frac{2}{3}[/tex]
Step-by-step explanation:
Given
3(q + [tex]\frac{4}{3}[/tex] ) = 2 ← distribute left side
3q + 4 = 2 ( subtract 4 from both sides )
3q = - 2 ( divide both sides by 3 )
q = - [tex]\frac{2}{3}[/tex]
Please Help: 0.125r - 0.0625 + 0.25r = 0.25 + r
Answer:
r=0.5
Step-by-step explanation:
0.125r+0.25r-0.0625=0.25+r
0.375r-0.0625=0.25+r
0.375r-r=0.25+0.0625
-0.625r=0.3125
r=0.3125/0.625

Find the length of AC¯¯¯¯¯¯¯¯ A. 36.5 B. 46.97 C. 74.63 D. 45.07
Answer:
[tex]a \: 36.5[/tex]
Step-by-step explanation:
cos51° = AC/58
AC = cos51° x 58
AC = 36.5
Answer:
The answer is option AStep-by-step explanation:
Since the figure above is a right angled triangle we can use trigonometric ratios to find AC.
To find AC we use cosine
cos∅ = adjacent / hypotenuse
From the question
AC is the adjacent
AB is the hypotenuse
So we have
[tex] \cos(51) = \frac{AC}{AB} [/tex]
[tex]AC = 58 \cos(51) [/tex]
AC = 36.5Hope this helps you

Change 95.61º to degrees, minutes, and seconds.

b. 95° 41' 43"
c. 950 36' 36'
d. 95° 44' 60"
Please select the best answer from the choices provided
Answer:
In my opnion, i think that the answer to your question is D. 95° 44' 60"
Step-by-step explanation:
if you were to break up each of these into segments, A, and B, would not add additionally to 95.61 degrees, minutes, and seconds. C is most definitly wrong because the inch mark, and foot" marks are wrong, and there is no degree mark. Espiecailly since its not possible to be 950 degree. Therefore, I would say option D is correct.

What is the smallest integer n such that 5n + 3 > -10
Answer:
[tex]solution set={n/n > -13/5}[/tex]
Step-by-step explanation:
[tex]5n + 3 > -10\\subtracting 3 on both sides\\5n + 3-3 > -10-3\\5n > -13\\n > -13/5 is the answer[/tex]
hope it will help :)
Isolate n:
5n + 3 > -10
Subtract 3 from both sides:
5n > -13
Divide both sides by 5:
n > -13/5
n > -2.6
An integer is a whole number, so the smallest whole number that would make the statement true would be -2:
5(-2) + 3 = -10 +3 = -7
5(-3) + 3 = -15 + 3 = -10
Since -7 is greater than -10, the answer is -2

solve by square roots 4x^2+11= 59
Answer:
x= ±2 sqrt(3)
Step-by-step explanation:
4x^2+11= 59
Subtract 11 from each side
4x^2+11-11= 59-11
4x^2 = 48
Divide by 4
4/4x^2 = 48/4
x^2 = 12
Take the square root of each side
sqrt(x^2) = sqrt(12)
x = ±sqrt(4*3)
x= ±2 sqrt(3)
Subtract 11 from each side
4x^2+11-11= 59-11
4x^2 = 48
Divide by 4
4/4x^2 = 48/4
x^2 = 12
Take the square root of each side
sqrt(x^2) = sqrt(12)
x = ±sqrt(4 x 3)
If:
AC=26,
BC=7x + 2, and
AB = 9x + 8
Find BC!
Answer:
BC = 9
Step-by-step explanation:
Given AC = 26
BC=7x + 2
AB = 9x + 8
Since BC and AB are two parts of AC. Therefore we can write in the following form.
AC = AB +BC
Now insert the given values in the above formula.
26 = 9x + 8 + 7x + 2
26 = 16x + 10
26 – 10 = 16x
16 = 16x
x = 16 / 16
x = 1
Now insert x = 1 in BC=7x + 2
BC = 7 (1) + 2
BC = 9
The sum of 20 numbers is 9. If each number were to be increased by 0.03, what is the sum of the 20 numbers in the end
Given that :-
Sum of 20 numbers is 9
To find
Sum of these numbers after increasing each number by 0.03
Solution :-
→ We have to increase each number by 0.03. It means that we have to add 20 times 0.03.
→ So the increase in sum of number will be 20(0.03)
→ 20(0.03) = 0.6
→ Earlier sum was 9.
After increase oof 0.6 new sum is 9+0.6

4 rational numbers that are not whole Numbers
Answer:
see below (I hope this helps!)
Step-by-step explanation:
Whole numbers are the integers that are greater or equal to 0. Basically, they are 0, 1, 2, 3....
Rational numbers can be written in the form a / b (where b ≠ 0 and a and b are integers (integers are ..., -1, 0, 1, ...))
Therefore, 4 rational numbers that are not whole numbers could be -5, -1, 0.5, and 3/4.
