Answer:

x= -1.118

Step-by-step explanation:

Firstly you need to start with the bracket

-5(5x +5) + 3(5x +3)

=( -25x +25) + (15x +9)

= -25x +25 +15x +9= -4x -6x

secondly you join the like terms together

25+9= -4x -6x +25x -15x

34= -38x

-38x ÷ 34

x= -1.118

Answer:

6

Step-by-step explanation:

5 x 120/100=6

Answer:

(-2, 6)

Step-by-step explanation:

Plug in one of the equations into the y-variable (doesn't matter which):

2x + 10 = -4x - 2

Combine like terms by adding the 4x to both sides. This makes it cancel out on the right side, and 2x + 4x on the right side is 6x:

6x + 10 = -2

Combine like terms by subtracting 10 from both sides, making it cancel out on the left side, and on the right: -2 - 10:

6x = -12

Then isolate the x-variable by dividing both sides by 6:

x = -2

Taking the -2, plug it into an x-variable in either of the equations:

y = 2x +10

y = 2(-2) + 10

y = -4 + 10

y = 6

Answer:

a) x = 8

b) x = 18

Step-by-step explanation:

Given that

9 : x : : 54 : 48

This may be rewritten as

9/x = 54/48

cross multiply

9 * 48 = 54 * x

Divide both sides by 54

x = 9 * 48/54

= 8

b Given that 2, 6, x are in continued proportion then

2/6 = 6/x

2 * x = 6 * 6

x = 36/2

= 18

Answer:[tex]\frac{1}{2}[/tex]

Step-by-step explanation:

With unlike denominators find the Least Common Denominator (LCD)

LCD = 12

Multiplying numerators and denominators to get the LCD in all fraction denominators

[tex]=\frac{3x3}{4x3}-\frac{1x4}{3x4}+\frac{1}{12}[/tex]

Then rewriting the equation with the equivalent fractions

[tex]=\frac{9}{12}-\frac{4}{12}+\frac{1}{12}[/tex]

With like denominators we can operate on just the numerators

[tex]=\frac{9-4+1}{12} =\frac{6}{12}[/tex]

Simplifying the answer

[tex]=\frac{1}{2}[/tex]

Answer:

When the discriminant value is zero, we get one real solution; When the discriminant value is negative, we get a pair of complex solutions; Standard Form. The standard discriminant form for the quadratic equation ax 2 + bx + c = 0 is. Discriminant, D = b 2 – 4ac. Where. a is the coefficient of x 2. b is the coefficient of x. c is a constant term.

B. 9/19

Step-by-step explanation:

there was 20 dogs in total he took 1 black dog now 19 in total, now 9 black dogs and 10 brown dogs so one less probability of black dogs so 9 black dogs and 10 brown dogs so 9/19

The other no. is:

32

As you can see that in the ratio given, 3 is the smaller no. and 12 too.

So when we divide 12 by 3, we get 4

Then to find the other no. we need to multiply 4 with 8 (which is the other no.          in the ratio given)

Therefore, we get the other no. as 32

And also when you divide 12 by 32,

You get the answer as 3 by 8 (which is the given ratio)

Hope you found this helpful!

Complete question :

Lucy has block letters that are in the shape of cubes with sides 2 3 foot long. She has a box which is 1 1 3 foot long, 2 3 foot wide, and 2 3 foot tall. Find the number of block letters that will fit in the box.

Answer:

1/2

Step-by-step explanation:

Number of block letters that will fit in :

Volume of box ÷ volume of each letter cube

Volume of each letter cube = (side length)³ = (2/3)³ = 8/27 ft³

Volume of box = length * width * height

Volume of box = 1 1/3 * 2/3 * 2/3

Volume of box = 4/3 * 2/3 * 2/3 = 16 / 27 ft³

Therefore ;

8/27 ÷ 16/27

8/27 * 27/16

= 8/16

= 1/2

Answer:

Equation for the total cost for pop music bundles = $ 1200 x + 300

Where variable is the Cost.

Equation for the total cost for rock music bundles = $ 950 x + 250

Where variable is the Cost.

Step-by-step explanation:

P.S - The exact question is -

Given - The Music Express is going to buy music bundles from a

             company that is going out of business. The company

             charges different amounts for bundles of pop and rock

             music:

             Cost for each pop music bundle is $1200

             Cost for each rock music bundle is $950

             One - time fee for rights to the pop music is $300

             One - time fee for rights to the rock music is $250.

To find - Write an equation that represents the total cost for pop

               music bundles.

              Write another equations to represent the total cost for rock

              music bundles.

              Identify the variables in the equations.

Proof -

Given that,

Cost for each pop music bundle is $1200.

Cost for each rock music bundle is $950.

One - time fee for rights to the pop music is $300.

One - time fee for rights to the rock music is $250.

Let the total music bundles buy = x

Now,

Given, Cost for 1 pop music bundle = $1200

⇒Cost for x pop music bundles = $ 1200 x

Also given,

One - time fee for rights to the pop music is $300.

∴ we get

Equation for the total cost for pop music bundles = $ 1200 x + 300

Where variable is the Cost.

Now,

Given, Cost for 1 rock music bundle = $950

⇒Cost for x pop music bundles = $ 950 x

Also given,

One - time fee for rights to the pop music is $250.

∴ we get

Equation for the total cost for rock music bundles = $ 950 x + 250

Where variable is the Cost.
