Answer:

You can't solve this unless you have the amount of the other alloy.

Step-by-step explanation:

For example, the question should be something like:

A jeweler is using 10 pounds of alloy that is 2% platinum. He has another alloy that is 5% platinum. He wishes to combine these mixtures to form a mixture that is 3% platinum. How many pounds of the second alloy should be added to the first to get a mixture that is 3% platinum?

Answer:

Larger number = 11

Smaller number = 6

Step-by-step explanation:

Let the larger number = x

Let the smaller number = y

x - y = 5

3y + 4 = 2x       Subtract 2x

-2x + 3y + 4 = 0

===========

Multiply  the first equation by 2. Write the second equation underneath

2x - 2y = 10

-2x + 3y + 4 = 0

add

y + 4 = 10  

Subtract from both sides

y = 10 - 4

y = 6

==========

x - y = 5

x - 6 = 5                Add 6 to both sides

x = 5 + 6

x = 11

Answer:

Step-by-step explanation:

x       ← the smaller number

x+5    ←  five more than the smaller number - the larger number

3x    ← three times the  smaller number

3x+4   ← four more than three times the  smaller number

2(x+5)   ← twice the larger number

3x + 4 = 2(x + 5)

3x + 4 = 2x + 10

   -4         -4

     3x = 2x + 6

  -2x       -2x

      x  =  6

x+5 = 6 + 5 = 11

Check:   3•6 + 4 = 22;  22:2 = 11

Answer:

7.alternate interior

x=64

8. same side interior

x=12

same side exterior

x=12

Answer:

Step-by-step explanation:

7. alternate angle or opposite angle are equal

   128 = 2x

    x = 128 / 2

    x = 64

8.  interior angles = 180

    180 = 72 + (7x + 24)

    180 - 72 - 24 = 7x

     x = 84 / 7

     x = 12

9.   same side angle = 180

     180 = 65 + (11x - 17)

     180 - 65 + 17 = 11x

     x = 132 / 11

     x = 12

Hope This Helps :)

Answer:

x = 4

Step-by-step explanation:

Step 1: Write equation

-3x + 20 = 8

Step 2: Solve for x

Step 3: Check

Plug in x to verify it's a solution.

-3(4) + 20 = 8

-12 + 20 = 8

8 = 8

the answer is 3/5

if that's not right I apologize

Answer:

3/5

Step-by-step explanation:

When dividing fractions, you change the division sign to multiplication and also flip the fraction that you are multiplying with.

So: 2/4 would become 4/2

3/10 x 4/2

12/20

Highest common factor between 12 and 20 is 4.

Divide both sided by 4:

3/5

Step-by-step explanation:

10x - 15 = 25

10x = 25 + 15

10x = 40

Divide both sides by 10

X = 4

Answer:50%

Step-by-step explanation:2 sides =100%/2=50

Answer:

The total would be $88

Step-by-step explanation:

First multiply $0.50 and 48 miles

$0.50x48=$24.00

Then add $24.00 and $64.00

$24.00+$64.00=$88.00

Hope this helps :)

Have a nice day :)

Answer:

mass, pressure, density is the right answer

Step-by-step explanation:

The three main characteristics that can be used to describe air are: C. mass, pressure, density.

Altitude deals with elevation of an object.

Radiation relates to transmission of energy through a medium in form of waves.

Air has mass, pressure, and density.

Therefore, the three main characteristics that can be used to describe air are: C. mass, pressure, density.

Step-by-step explanation:

Given,

LP = 15, PR = 9

Point P lies on the line segment PR. It would mean that,

LP + PR = LR

⇒LR = 15 + 9

⇒ LR = 24

Hence, "LR = 24 because LP + PR = LR according to the Segment Addition Postulate, and 15 + 9 = 24 using substitution" is the correct option.

Answer:

RS = 14

Step-by-step explanation:

Perimeter = 26 + 26 + PT + RS

We know that PT and RS are equal to each other so I changed the equation to 26 + 26 + x + x = 10 + 5x and then I got x by itself and the integer on one side 42 = 3x, so 14 = x

The value of RS will be 14 for the given parallelogram.

A basic quadrilateral with two sets of parallel sides is known as a parallelogram.

A parallelogram's facing or opposing sides are of equal length, and its opposing angles are of similar size.

There are 4 types of parallelograms, including 3 special types. The four types are parallelograms, squares, rectangles, and rhombuses.

Given the parallelogram where TS ║ PR and both are equal

Line TP ║ SR so it means TP = SR

Let's say

TP = SR = x

Now,

The perimeter of a parallelogram is 10 more than 5(RS)

So,

PT + TS + SR + RP = 5(RS) + 10

Now since TP = RS = x

So,

x + TS + x + RP = 5x + 10

5x - 2x = TS + RP - 10

x =  (TS + RP - 10)/3

Now,

TS = RP = 26

So,

x = (26 + 26 - 10 )/3

x = 42/3

x = 14

Hence "The value of RS will be 14 for the given parallelogram".

Step-by-step explanation:

Let's make the number we're finding to be [tex]a[/tex]. So, it says that it will be divided by 4 and then added by 12 if we want this in algebraic expression it will be [tex]\frac{a}{4} +12\\[/tex]. It's also telling us that that expression is the same thing as our number divided by 3 and subtracted by 5. If we want an expression out of it it well be [tex]\frac{a}{3} -5\\[/tex]. Since they are the same, we have the equation below.

[tex]\frac{a}{4} +12 = \frac{a}{3} -5\\[/tex]

All we have to do now is to find [tex]a[/tex].

[tex]\frac{a}{4} +12 = \frac{a}{3} -5 \\ \frac{a +48}{4} = \frac{a -15}{3} \\ (3)(a +48) = (a - 15)(4) \\ 3a +144 = 4a -60 \\ (60 -3a) + 3a +144 = 4a -60 +(60 -3a) \\ a = 204[/tex]

Our number must be [tex]204[/tex]. I think

Given problem:

 What is 9*5;

 The formula P*Q  = P x Q  - 7;

To  find 9*5, simply make P = 9 and Q = 5

Input into the equation and solve;

   P*Q  = P x Q  - 7    =   9 x 5 - 7

                                 = 45 - 7

                                 = 38

I dont understand, sorry. I dont understand the diffrtence between the orders It makes no sense whatsoever

Answer:

C, B, A.

Step-by-step explanation:

Given:

Four equations are

[tex] 7 x + 1 = 7 x+ 1[/tex]

[tex]3 x + 2 = 3 x-2[/tex]

[tex]4 x + 1 = 3 x + 8[/tex]

[tex]-2x-1 = -2 x-1[/tex]

To find:

Without solving which equation has no solution.

Solution:

We know that, in an equation

1. No solution : When variable terms are same but constants are different.

2. Unique solution : When variable terms are different.

3. infinitely many solution : When variable terms and constants are same.

In first and fourth equations, terms on left sides are equal to the terms on the right side. So, LHS = RHS for any value of x.

Therefore, these two equations (first and fourth) have infinitely many solutions.

In second equation, variable terms are same on both sides, but the constants are difference. So, LHS ≠ RHS for any value of x.

Therefore, the second has no solutions.

In third equation, coefficient of x are difference on both sides.

So, this equation has unique solution.

Therefore, Jubal's equations [tex]3 x + 2 = 3 x-2[/tex] has no solution. Hence, the correct option is B.
