Answer:

x = -2 5/14

Step-by-step explanation:

7(x + 6) + 7x = 9

First, open the parenthesis.

7x + 42 + 7x = 9

Combine like terms.

7x + 7x + 42 = 9

14x + 42 = 9

Subtract 9.

14x = -33

Divide.

x = -33/14

Simplify.

x = -2 5/14

X < 12

or x is equal to 12 im not really sure...

but the answer is 4, 4<4, so it is equal

Step-by-step explanation:

After multiplication of pair of complex numbers, the results of product are respectively 45, 41, 73

The complex number is a combination of real number and imaginary number. The representation of complex number is like, a + bi.

where a is real part and b is imaginary part, the value of i is √-1.

i × i = -1

i⁴ = 1

Given that, pair of complex numbers

(6 +3i )×( 6 - 3i) =  6×6 -6×3i + 6×3i - (3i × -3i)

                         = 36 - 18i + 18i + (-3i × 3i)

                         =  36 + 9

                         =  45

(4-5i) × (4+5i)   =  4×4 + 4×5i - 4×5i - (5i × -5i)

                        = 16 - 20i + 20i + (-5i × 5i)

                        = 16+25

                        = 41

(-3+8i) × (-3-8i) = -3×-3 + (-3× -8i) - 3×8i + (8i × -8i)

                        = 9 +24i-24i +64

                        =  73

Hence, The result of products are 45, 41, 73

Answer: (6 + 3i)(6 − 3i) = 45, (4 − 5i)(4 + 5i) = 41, (−3 + 8i)(−3 − 8i) = 73

Step-by-step explanation:

Since there is a negative on the y term, we need to get rid of that and thus flip the sign at the same time. Getting.

-43>8/3y

Now we just need to divide 8/3 on both sides dividing 8/3 on left can also be written as *3/8

-43*3/8>y

Now flip this entire equation

y<-43*3/8

y<-129/8

If your teacher want you to calculate just divide the fraction, but I recommend not to if your teacher don't ask for it and just leave it this way.

Step-by-step explanation:

[tex]f^{3}[/tex] + 11g - 4h

f = 3, g = 2 and h = 7.

Substitute the above values into the expression.

[tex]3^{3}[/tex] + 11 × 2 - 4 × 7

Since there's no addition, subtraction or division signs between 11g and 4h, this basically shows that it is multiplied. Simplify further...

[tex]3^{3}[/tex] is 3×3×3 which equals to 27

11 × 2 equals to 22, and

-4 × 7 = -28

Put all these found values into an expression.

27 + 22 - 28

Use the B.O.D.M.A.S. rule. First we have to add then subtract.

(27 + 22) - 28

49 - 28 = 21

Answer: 60

Step-by-step explanation:

Answer:  The value of ∠K is 56°.

Step-by-step explanation:

Given: A pair of triangles Δ EDC ~ Δ KGH

∠E = 56°  and ∠H = 34° .

Since corresponding angles of similar triangles are equal.

⇒∠E = ∠K               ...(i)

⇒∠D = ∠G

⇒∠C = ∠H

∠E = 56°    [Given]

⇒∠K =  56°    [From (i)]

Hence, the value of ∠K is 56°.

Answer:

  z + y = 52; z - y = 10; z = 31; y = 21; $9.85 total

Step-by-step explanation:

The variables are defined in the problem statement. The equations could be ...

  z + y = 52 . . . . . . total number of coins

  z - y = 10 . . . . . . . 10 more quarters than dimes

These equations can be solved by adding them together.

  (z +y) +(z -y) = (52) + (10)

  2z = 62 . . . . . . . simplify

  z = 31 . . . . . . . . . divide by 2

  31 -10 = y = 21 . . . . find the number of dimes

There are 31 quarters and 21 dimes.

The value of the coins is ...

  31($0.25) +21($0.10) = $7.75 +2.10 = $9.85

Answer:

4 pitches

Step-by-step explanation:

if a cylinder with height 9 inches and radius r is filled with water, it can fill a certain pitcher. how many of these pitchers can a cylinder with height 9 inches and radius 2r fill? explain how you know.

Solution:

The volume of a cylinder is given by:

V = πr²h;

where V is the volume, r is the radius of the cylinder and h is the height of the cylinder.

A cylinder with height 9 inches and radius r can fill a certain pitcher. Therefore the volume of the cylinder is:

V = πr²h = πr²(9) = 9πr²

V = volume of pitcher = volume of cylinder with radius r = 9πr²

For a cylinder with height 9 inches and radius 2r its volume is:

V2 = πr²h = π(2r)²(9) = 36πr²

Therefore, the number of pitchers a cylinder with height 9 inches and radius 2r can fill is:

number of pitches = 36πr² / 9πr² = 4

Therefore a cylinder with height 9 inches and radius 2r can fill 4 pitches.

Answer:

24.75 is 55% of 45

Step-by-step explanation:

Answer:

45

Step-by-step explanation:

Form an equation

let x be the number you're looking for

that means 55% of x, or 0.55x is 24.75

So you can make this equation:

0.55x = 24.75

multiply both sides by 100 to get rid of the decimal

55x = 2475

divide both sides by 55 to solve for x

x = 45

The number is 45

Answer:

7569.36

Step-by-step explanation:

Given that a quantity with an initial value of 7800 decays continuously at a rate of 0.1% per hour. What is the value of the quantity after 1.25 days, 

First convert 1.25 days to hours

1.25 × 24 = 30 hours

Using exponential equation

N = No ( 1 - R% )^t

Where N = new value of the quantity

No = initial value

R = rate

t = time

N = 7800 ( 1 - 0.001 )^30

N = 7800 ( 0.999 )^30

N = 7800 × 0.97043

N = 7569.36154

N = 7569.36 to the nearest hundredth.

Therefore, the value of the quantity after 1.25 days is 7569.36

Step-by-step explanation:

We can look at the missing side as part of a right triangle

We have 24 as one side and 25 as the hypotonouse

we have

24²+x²=25²

solve for x

25²-24²=49

x²=49

x= ±7

but it obviously can't be negative so x=7
