5 less would be -5

twice a number would be *2

so the expression would be

2x - 5

Answer:

2x - 5

Step-by-step explanation:

let assume the number is x:

Therefore 2x - 5

Answer:

= 9

Step-by-step explanation:

There are two angles given.

One is 90 and the other is 45.

90+45=135

180-135=45°

This proves that the triangle is isosceles.

This means that two angles are equal, but also two side lengths are the same.

In this triangle, the equal sides are CB and AC.

Therefore, AC is equal to 9.

Answer:

Choice #4 is the most likely fit.

Answer:

n = - [tex]\frac{4}{7}[/tex]

Step-by-step explanation:

Given

[tex]\frac{2}{3}[/tex] (1 + n) = - [tex]\frac{1}{2}[/tex] n

Multiply both sides by 6 ( the LCM of 3 and 2 ) to clear the fractions

4(1 + n) = - 3n ← distribute left side

4 + 4n = - 3n ( add 3n to both sides )

4 + 7n = 0 ( subtract 4 from both sides )

7n = - 4 ( divide both sides by 7 )

n = - [tex]\frac{4}{7}[/tex]

Answer:

Step-by-step explanation:

The answer is (Sonya only) don’t know the explanation but I literally got the answer right soo trust me.

Answer:

3V/ (pi r^2) = h

Step-by-step explanation:

V = 1/3 pi r^2 h

Solve for h

Multiply each side by 3

3V = 3 * 1/3 pi r^2 h

3V =  pi r^2 h

Divide each side by pi r^2

3V/ (pi r^2) = pi r^2 h/ ( pi r^2)

3V/ (pi r^2) = h

Answer:

309 full rolls

Step-by-step explanation:

Find how many full rolls he had by dividing 15,483 by 50:

15,483/50

= 309.66

Since the question asks for full rolls, the answer has to be a full number.

So, the answer is 309 full rolls

Answer:

The magnitude of the resultant force is: 27.40 pounds

Step-by-step explanation:

Given

[tex]F_1 = 45[/tex]

[tex]F_2 = 50[/tex]

[tex]\theta = 33[/tex]

Required

The magnitude of the resultant vector

To do this, we apply cosine formula

[tex]R^2 = F_1^2 + F_2^2 - 2 * F_1 * F_2 * \cos(\theta)[/tex]

This gives:

[tex]R^2 = 45^2 + 50^2 - 2 * 45 * 50 * \cos(33)[/tex]

[tex]R^2 = 2025+ 2500 - 4500* 0.8387[/tex]

[tex]R^2 = 2025+ 2500 - 3774.15[/tex]

[tex]R^2 = 750.85[/tex]

Take square roots of both sides

[tex]R = \sqrt{750.85\\[/tex]

[tex]R = 27.40[/tex]

Answer:

8 red haired and 42 brown haired

Step-by-step explanation:

I chose a random number to start off with (which is 8) and I multiplied it by 5.

8•5=40 and then you have to add 2, so you get 42.

42+8 = 50

The equation would be (5x+2)+x where 'x' is the number of people with red hair.

Answer:

B) all real numbers expect 4pi+8pi where n is any integer

Step-by-step explanation:

The domain of the function y = tan(x/8) is given by: All real numbers except 4π+8nπ , where n is any integer.

The domain is the set that contains all possible input values for the function.

Since we know that Tangent of an angle is sine of the angle divided by the cosine of the angle, and the cosine is 0 at:

π/2 + nπ

Hence, let a composite tangent function , the domain is given by:

f(x) does not equal to π/2 + nπ

we have that , hence the domain is:

all real numbers except 4π+8nπ

All real numbers except 4π+8nπ, where n is any integer.

#SPJ7

Answer:

about 7.3 units

Step-by-step explanation:

to find the answer you do Pythagorean theorem

so you have (-9, -4) and (-2, -6)

you do X1-X2 and Y1-Y2

so -4-(6)=2

and -9-(-2)= -7

now you do a^2 + b^2 = C^2

so 2^2 + -7^2 = C^2

which is 4 + 49= C^2

53=C^2

√53=7.3

so 7.3 units :)

Answer:

a. Yes

b. 3x+7

c. 105 cm

Step-by-step explanation:

a. a(1)+b=10

   a(2)+b=13

when you solve this by elimination or simultaneously: a=3 and b=7

∴ f(x)=3x+7

b. f(x)=3x+7

c. 3(35)+7=112 cm

Answer:

B. 2/9

Step-by-step explanation:
