Charlotte drives 7.6 miles round trip to work every day. How many miles does she drive to
and from work in 9 days?

Answer:

A

Step-by-step explanation:

-5 i s greater than -2.

Nope that aint true

-2 is greater than -5 is correct since -2 is closer to the postivie numbers and zero.

-5 is farther so it is less than -2.

Answer:

Step-by-step explanation:

a. Fill in the equation for the cost of Mrs. Ortiz's purchase. Let x represent the cost of a pencil and y represent the cost of a ruler.

__$55__ = __50__ x + __30_ y

b. Fill in the equation for the cost of Mr. Donahue's purchase. Let x represent the cost of a pencil and y represent the cost of a ruler.

__$45__ = __30__ x + __30__ y

c. Circle the best method for solving the system:

Elimination

d. Solve the system using the method you chose.

  55 =50x+30y

  -1(45) =(30x+30y)-1     =     -45=-30x-30y

    55 =50x+30y

+  -45=-30x-30y

   10=20x

(1/20)10=20x(1/20)

0.50=x

3(55) =(50x+30y )3      =     165=150x+90y

-5(45) =(30x+30y)-5     =   -225=-150x-150y

     165 =150x+90y

+  -225=-150x-150y

           -60=-60y

(1/-60)-60=-60y(1/-60)

             1=y

A mechanical pencil costs _$0.50__ and a ruler costs __$1.00__.

e. Check your answer:

$55=50x+30y                                $45=30x+30y

$55=50(0.5)+30(1)                         $45=30(0.5)+30(1)

$55=25+30                                    $45=15+30

$55=$55                                         $45=$45

A mechanical pencil costs $0.50  and a ruler costs $1.00.

The current answer as follows:

a. Fill in the blanks to calculate Mrs. Ortiz's purchase price. Let x denote the price of a pencil and y the price of a ruler.

$55 = 50x + 30y

b.Fill in the blanks with the cost of Mr. Donahue's purchase. Let x represent the cost of a pencil and y represent the cost of a ruler.

$45 = 30x + 30y

c. Circle the best method for solving the system:

Elimination

d. Solve the system using the method you chose.

55 = 50x + 30y - 1(45) = (30x + 30y) - 1 = -45 = -30x - 30y

  55 = 50x + 30y + -45 = -30x - 30y

 10 = 20x

(1/20)10 = 20x (1/20)

0.50 = x

3(55) = (50x + 30y )3 = 165 = 150x + 90y

-5 (45) = (30x + 30y) - 5  = -225 = -150x - 150y

   165 = 150x + 90y + -225 = -150x - 150y

         -60 = -60y

(1/-60) -60 = -60y (1/-60)

           1 = y

A mechanical pencil costs $0.50  and a ruler costs $1.00.

Answer:1) 14/5 isnt right, it would be more miles in less time. 2) [tex]\frac{5}{14}[/tex] Is the correct way. 3) 9 hours, 20 mins

Step-by-step explanation:

The proportion Jamie should set up is 14/5=25/x  and 9 hours will it take Jamie to walk 25 miles

A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0. A proportion is an equation in which two ratios are set equal to each other.

Given that In 5 hours, Jamie walked 14 miles.

Jamie is trying to figure out how many hours it would take to walk 25 miles.

She set up the proportion 14/5=x/25.

The error Jamie make in setting up her proportion is in LHS taken as miles per hours but in RHS the set up is hours by miles.

In both sides same set up should be maintained.

14/5=25/x is the proportion she should have used

14/5=25/x

Apply cross multiplication

14x=25(5)

14x=125

x=125/14

x=8.92=9

Hence, the proportion Jamie should set up is 14/5=25/x  and 9 hours will it take Jamie to walk 25 miles

Answer:

The degree of the remainder should be 4 for the division process to be stopped

Step-by-step explanation:

From the question, we have the degree of the divisor as 5

So, for the division process to be stopped, the degree of the remainder should be one less than the degree of the divisor

Once the degree of the remainder is less than the degree of the divisor, we have no option that to stop and not proceed further with the division

So in the case of the particular question, the degree of the remainder should be of degree 4

sin 28° = 8/17

Step-by-step explanation:

sin A = opp/hyp

sin 28° = 8/17

The value of sin 28° is: sin 28° = 8/17

So, Option B is correct.

Here, given that, a right angle triangle has hypotenuse = 17 units,

height = 8 units,

base = 15 units.

now, we have, the angle between hypotenuse and base is: sin 28°.

from trigonometry we know that,

sin A = opp/hyp

so, here, we get, sin 28° = height/hypotenuse

putting the values, we have,

sin 28° = 8/17

Hence, The value of sin 28° is: sin 28° = 8/17

So, Option B is correct.

There are 20 trials in total.

It says that the numbers 4 and 5 represent SUVs. All we have to do is look and count how many trials of the 20 that have the number 4 or 5.

That would be 9 trials that have the number 4 or 5 within it. Then you divide them. 9/20 = 0.45 or 45%

y=1(3)^x

Step-by-step explanation:

First take the y and do 3/1

Then take x and do 1-0

Then do 3(sqrt)1 which is just 3

3 is ur b value

Then it is y=1(3)^x

The final statement is: The value of x is 1/6

Linear equations help in representing the relationship between variables such as x, y, and z, and are expressed in exponents of one degree. In these linear equations, we use algebra, starting from the basics such as the addition and subtraction of algebraic expressions.

Given here:   The expression x+2/3=5/6

substracting -2/3 both sides   x=5/6-2/3

                                                      x=1/6

Answer:

x = 1/6

Step-by-step explanation:

Given equation,

→ x + (2/3) = 5/6

Now the value of x will be,

→ x + (2/3) = 5/6

→ x = (5/6) - (2/3)

→ x = (5/6) - (4/6)

→ x = (5 - 4)/6

→ [ x = 1/6 ]

Hence, the value of x is 1/6.

  yes, if you allow complex numbers; no, if you don't

Step-by-step explanation:

The sum of squares can be considered to be the difference of squares, where one of the squares is negative. The negative square is the square of an imaginary number, so the factoring involves imaginary numbers.

  x^2 +25 = x^2 - (-25) = x^2 -(5i)^2

Solution of the given system of equations

 x = 3 and  y= 2

Step-by-step explanation:

Step(i):-

Given system of equations are

                                      4x - y =  10 ...(i)

                                     8x +5y = 34...(ii)

The matrix form

                          A X = B

[tex]\left[\begin{array}{ccc}4&-1\\8&5\\\end{array}\right] \left[\begin{array}{ccc}x\\y\\\end{array}\right] = \left[\begin{array}{ccc}10\\34\\\end{array}\right][/tex]

Step(ii):-

By using matrix inversion method

[tex]A^{-1} = \frac{1}{|A|} adj A[/tex]

|A| = ad-b c = 4(5) - 8(-1) = 20+8 = 28

Given matrix

            [tex]A = \left[\begin{array}{ccc}4&-1\\8&5\\\end{array}\right][/tex]

[tex]AdjA = \left[\begin{array}{ccc}d&-b\\-c&a\\\end{array}\right][/tex]

[tex]A djA = \left[\begin{array}{ccc}5&1\\-8&4\\\end{array}\right][/tex]

Inverse of the matrix

                           [tex]A^{-1} = \frac{1}{|A|} adj A[/tex]

                          [tex]A^{-1} = \frac{1}{|A|} A djA =\frac{1}{28} \left[\begin{array}{ccc}5&1\\-8&4\\\end{array}\right][/tex]

Step(iii):-

The solution of the given system of equations by using matrix inversion method

                     X = A⁻¹ B

                    [tex]X = A^{-1}B =\frac{1}{28} \left[\begin{array}{ccc}5&1\\-8&4\\\end{array}\right]\left[\begin{array}{ccc}10\\34\\\end{array}\right][/tex]

                   [tex]X = A^{-1}B =\frac{1}{28} \left[\begin{array}{ccc}5X10+1X34\\-8X10+4X34\\\end{array}\right][/tex]

                 [tex]\left[\begin{array}{ccc}x\\y\\\end{array}\right] =\frac{1}{28} \left[\begin{array}{ccc}84\\56\\\end{array}\right][/tex]

                 [tex]\left[\begin{array}{ccc}x\\y\\\end{array}\right] = \left[\begin{array}{ccc}3\\2\\\end{array}\right][/tex]
