Answer:

6 is larger unless -45 is in brackets then its bigger

Step-by-step explanation:

No negative number is bigger than positive numbers, unless it has brackets

Answer:

-45

Step-by-step explanation:

The negative is in brackets making it positive and 45 is greater than 6

Answer:

The value of x = 15

Hence,

Step-by-step explanation:

We know that the perimeter of a triangle is the sum of all the sides of a triangle.

Given

Perimeter = 58 in

AB = x

BC = 2x+1

AC = x-3

so the equation becomes

Perimeter = AB + BC + AC

    58        = x + 2x+1 + x-3

     58        = 4x - 2

     4x  = 58+2

     4x = 60

     4x/4 = 60/4

      x = 15

Thus, the value of x = 15

Hence,

VERIFICATION

Perimeter = AB + BC + AC

58 = 15+31+12

58 = 58

Answer: D

Step-by-step explanation:

X is 0 so it would be intercepting the graph at -2

Answer:

A,-7

B, 4

C,13

D,2

Step-by-step explanation:

A,Step 1: Divide both sides by 4.

[tex] \frac{4x}{4} = \frac{ - 28}{4} [/tex]

[tex] x = - 7[/tex]

B,Step 1: Add 6 to both sides.

x−6+6=−2+6

x = 4

C, Step 1: Regroup terms.

4−Y=−9

Step 2: Subtract 44 from both sides.

-Y=-9-4−Y=−9−4

Step 3:Simplify -9-4−9−4 to -13−13.

[tex] \frac{ - y}{1} = \frac{ - 13}{ - 1} [/tex]

Y = 13

D,Subtract 77 from both sides.

-3x=1-7−3x=1−7

2, Simplify 1-71−7 to -6−6.

-3x=-6−3x=−6

3,Divide both sides by −3.

[tex] x = \frac{ - 6}{ - 3} [/tex]

4,Two negatives make a positive.

x = 6/3

x = 2.

Answer:

The appropriate response will be "Zero (0)". A further explanation is given below.

Step-by-step explanation:

The response is therefore "0".

you add 78 plus 37 then subtract from 180

Answer:

65°

Step-by-step explanation:

Let the unknown angle be ∠ABC

∠ABC + 78° + 37° = 180° (angle sum property of a triangle)

∠ABC + 115° = 180°

∠ABC = 180° - 115°

∠ABC = 65°

∴the unknown angle in the triangle is 65°

Answer: 12/7 or 1 5/7 of a mile

Step-by-step explanation: To get to 1 mile, you multiply 1/3 by 3. Then multiply 4/7 by 3. That should give you your answer. Hope this helped!

Answer:

-6

Step-by-step explanation:

Answer:

x-1

Step-by-step explanation:

The solution to the equation 21 = 14 + 7x is x = 1.

Given the equation in the question:

21 = 14 + 7x

To solve the equation 21 = 14 + 7x, start by isolating the variable x to one side of the equation:

21 = 14 + 7x

Subtract 14 from both sides of the equation:

21 - 14 = 14 - 14 + 7x

Add 14 and -14:

21 - 14 = 7x

Subtract 14 from 21:

7 = 7x

Reorder the equation:

7x = 7

Divide both sides by 7:

7x/7 = 7/7

x = 7/7

x = 1

Therefore, the value of x is 1.

Answer:

The width of the foil = w = 2.5 inches

Step-by-step explanation:

We know that the Area of a rectangular piece:

[tex]A=wl[/tex]

Here:

Given that area of the rectangular piece of foil:

Area = A = 11 1/4 square inches

               = 45/4 square inches

               = 11.25 square inches  

Length = l = 4 1/2 inches

                 = 9/2 inches

                 = 4.5 inches

Using the Area formula

[tex]A=wl[/tex]

[tex]w\:=\:\frac{A}{l}[/tex]

    [tex]=\frac{11.25}{4.5}[/tex]

    [tex]= 2.5[/tex] inches

Thus, the width of the foil = w = 2.5 inches

Answer:

Step-by-step explanation:

I think it would be 5

Answer:

you are asking what dont understand

Step-by-step explanation:

Answer:

5 + 2i

We were given the complex numbers;

a = - 2 - 5i

and

b = - i

We want to find the product;

ab^3                            ^ = Exponent

We substitute the complex numbers into the expression and simplify

( - 2 - 5i ) (i)^3                     ^ = Exponent            

This is rewritten as:

( - 2 - 5i) (i)^2     x  i                           ^ = Exponent

Note that

i^2 = - 1                                            ^ = Exponent

We substitute to obtain:

( - 2 - 5i )  x  - i                

Let us expand to get:  

- 2 x - i + 5i  x  - i

This simplifies to:

2i - 5i^2                           ^ = Exponent

This gives:

2i - 5 ( - 1 ) = 2i + 5

The value of ab³ in simplified form is;  -250(i + 1).

Equations are mathematical expressions that have two algebras on either side of an equal (=) sign. The expressions on the left and right are shown to be equal, demonstrating this relationship. L.H.S. = R.H.S. (left-hand side = right side) is a fundamental simple equation.

From the given values in the question we have;

a = -2 + 2i

b = -5i

Thus

ab³ = (-2 + 2i) × (-5 i)³

=  (-2 + 2i) (-125 i³)

=  (-2 + 2i) (-125 (-i))

=  (-2 + 2i) (+125 i)

= 125 i(-2) + 125 i(2i)

= -250 i + 250 i²

= -250 i -250 or,

ab³ = -250 (i+1)
