Answer:

11 pints of milk the Garcia family have left after lunch.

Step-by-step explanation:

The Garcia family started the day with 2 gallons of milk.

They drank 1 quart of milk for breakfast and 3 pints for lunch.

Since, 1 gallon = 8 pint

2 gallon = 16 pint

and 1 quart = 2 pint

Left amount = 16 pint - ( 2pint + 3pint)

= 16-5

= 11 pints

Hence, 11 pints of milk the Garcia family have left after lunch.

Answer:

Step-by-step explanation 121 is the answer and it doesn't let me show work.

Given:

A line passes through (1,-2) and is perpendicular to [tex]-4x+7y=21[/tex].

To find:

The equation of that line.

Solution:

We have, equation of perpendicular line.

[tex]-4x+7y=21[/tex]

Slope of this line is

[tex]m_1=-\dfrac{\text{Coefficient of x}}{\text{Coefficient of y}}[/tex]

[tex]m_1=-\dfrac{-4}{7}[/tex]

[tex]m_1=\dfrac{4}{7}[/tex]

Product of slope of two perpendicular lines is -1.

[tex]m_1\times m_2=-1[/tex]

[tex]\dfrac{4}{7}\times m_2=-1[/tex]

[tex]m_2=-\dfrac{7}{4}[/tex]

Now, slope of required line is [tex]-\dfrac{7}{4}[/tex] and it passes through (1,-2). So, the equation of line is

[tex]y-y_1=m(x-x_1)[/tex]

where, m is slope.

[tex]y-(-2)=-\dfrac{7}{4}(x-1)[/tex]

[tex]4(y+2)=-7(x-1)[/tex]

[tex]4y+8=-7x+7[/tex]

[tex]4y+7x=7-8[/tex]

[tex]7x+4y=-1[/tex]

Therefore, the equation of required line is [tex]7x+4y=-1[/tex].

Answer:

r - 18

Step-by-step explanation:

Less than means you put the 18 behind the r

Less than means subtraction

The expression for the phrase 18 less than the number r is r - 18.

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

18 less than a number r.

Number = r

This means,

r - 18

Thus,

The expression is r - 18.

Answer:

68 degrees

Step-by-step explanation

If <3 and <4 are vertical angles, then <3 = <4

This means that

9x + 5 = 5x + 33

9x - 5x  = 33 - 5

4x = 28

x = 28/4

x = 7

Since <4 = 5x+ 33

<4 = 5(7) + 33

<4 = 35 + 33

<4 = 68 degrees

Hence the measure of <4 is 68 degrees

Answer:

x = 2

Step-by-step explanation:

Both equations are equal to y, so they're also equal to each other.  We then set them equal to each other:

x^2 - 2x + 1  =  x^2 + 2x - 7

We now do algebra to isolate x.  Subtract 1 from both sides.

x^2 - 2x  =  x^2 + 2x - 8

Subtract 2x from both sides.

x^2 - 4x  =  x^2 - 8

Subtract x^2 from both sides.

-4x = -8

Divide both sides by -4.

x = 2

Answer:

x = 4 , y = 2

Step-by-step explanation:

3x+9y = 30 --------- (1)

2(3x+9y)+x = 64 ---------(2)

substitute (1) into (2)

2(30)+x = 64

60+x = 64

x = 64-60

x = 4

substitute x=4 into (1)

3x+9y = 30

3(4)+9y = 30

12+9y = 30

9y = 30-12

9y = 18

y = 18/9

y = 2

thus, x = 4 and y = 2

Answer:

24% saline

Step-by-step explanation:

Find how much saline is in both solutions:

7(0.27)

= 1.89

3(0.17)

= 0.51

Add this together:

1.89 + 0.51

= 2.4

Since there are 10 quarts in total, the concentration of the mixture can be found by dividing 2.4 by 10:

2.4/10

= 0.24

So, the concentration of the mixture is 24% saline

Answer:

Step-by-step explanation:

use known angles and rules to find unknown values

vertical angles (pairs of angles on opposite sides of an intersection) are equivalent

supplementary angles (angles found next to each other on a line) add up to 180 degrees

opposite interior angles are equivalent

And I don't remember the name of this kind of angle, but angle 1 and 10 are equivalent because they are found on the same "location"

using these rules you can find all missing angles.

1= 75

2=180-75=105

Answer:

Number of necklaces = 8

Number of bracelets = 20

Step-by-step explanation:

Given that:

Mellisa is making and selling the necklaces and bracelets.

Number of pieces of jewelry made on one day = 28

Number of bracelets was 4 more than the twice the number of necklaces.

To find:

Number of each type of jewelry made = ?

Solution:

Let number of bracelets = [tex]b[/tex]

Let number of necklaces = [tex]n[/tex]

As per question statement:

[tex]b+n=28[/tex] ...... (1)

[tex]b = 2n+4[/tex] ...... (2)

Putting the value of [tex]b[/tex] in equation (1):

[tex]2n+4+n=28\\\Rightarrow 3n = 28-4\\\Rightarrow 3n = 24\\\Rightarrow n =\bold{8}[/tex]

By equation (1):

[tex]b + 8 =28\\\Rightarrow b = \bold{20}[/tex]

So, the answer is:

Number of necklaces = 8

Number of bracelets = 20

France = 75

The difference between the number of stamps between Germany and France.

= 75 - 59

= 16

Thus,

There are 16 more stamps from France than Germany.
