Answer:

a) When x = 3, both expressions have a value of 30. When x = 5, both expressions have a value of 42.

b) When x = 1, both expressions have a value of 18, and when x = 8, both expressions have a value of 60.

Step-by-step explanation:

Which best proves why the expressions 4 (x + 3) + 2 x and 6 (x + 2) must be equivalent expressions?

Mathematically this is expressed as:

4(x + 3) + 2x = 6(x + 2)

Verifying the options

a) When x = 3, both expressions have a value of 30. When x = 5, both expressions have a value of 42.

When x = 3

4(x + 3) + 2x = 6(x + 2)

4(3 + 3) + 2(3)= 6(3 + 2)

24 + 6 = 6(5)

30 = 30

When x = 5

4(x + 3) + 2x = 6(x + 2)

4(5 + 3) + 2(5)= 6(5 + 2)

4(8) + 10 = 6(7)

42 = 42

Statement in option a is correct

b) When x = 1, both expressions have a value of 18, and when x = 8, both expressions have a value of 60.

When x = 1

4(1 + 3) + 2x = 6(x + 2)

4(1 + 3) + 2(1)= 6(1 + 2)

4(4) + 2 = 6(3)

18 = 18

When x = 8

4(8 + 3) + 2x = 6(8 + 2)

4(11) + 2(8)= 6(8 + 2)

44 + 16 = 6(10)

60 = 60

Statement in option b is correct

c) When x = 2, both expressions have a value of 15, and when x = 6, both expressions have a value of 39.

When x = 2

4(x + 3) + 2x = 6(x + 2)

4( 2 + 3) + 2(2)= 6(2 + 2)

4(5)+ 4 = 6(4)

20 + 4 = 6(4)

24 = 24

4(x + 3) + 2x = 6(x + 2)

4(6 + 3) + 2(6)= 6(6 + 2)

4(9) + 12 = 6(8)

48 = 48

Statement in Option c is wrong

Hence, Statement in Option a and b is correct

Given:

Rachel used [tex]\dfrac{1}{3}[/tex] of her savings to buy brushes.

She used [tex]\dfrac{3}{5}[/tex] of her savings to buy paint.

To find:

The fraction for remaining savings.

Solution:

Fraction that Rachel used of her savings to buy brushes and paint is

[tex]\text{Fraction for used amount}=\dfrac{1}{3}+\dfrac{3}{5}[/tex]

                                    [tex]=\dfrac{5+9}{15}[/tex]

                                    [tex]=\dfrac{14}{15}[/tex]

Now,

[tex]\text{Fraction for remaining savings}=1-\text{Fraction for used amount}[/tex]

[tex]\text{Fraction for remaining savings}=1-\dfrac{14}{15}[/tex]

[tex]\text{Fraction for remaining savings}=\dfrac{1}{15}[/tex]

Therefore, [tex]\dfrac{1}{15}[/tex] of her savings is remaining.

Answer:

Mother = $80

Father = $120

Step-by-step explanation:

Given that :

Earning = $400

Amount gotten from mother = 20% of earning

Amount gotten from father = 30% of earning

Amount gotten from each parent :

MOTHER :

0.2 * $400 = $80

FATHER :

Answer:

samatha is 32 hunter is 18

Step-by-step explanation:

trial and error

We must find the slope of the original line using slope formula*.

[tex]m = \frac{19 - 15}{13 - 13} = \frac{5}{0} = 0[/tex]

Because the given points have the same x-coordinate, the slope is 0.

Given that the original line doesn't have slope, the other two lines won't have one either.

Answer:

-3

Step-by-step explanation:

Let the unknown number be n

We are to write the expression as equation;

Six times a number plus 4 is the same as the number minus 11.

Six times a number is given as;

6n

Six times a number plus 4 is expressed as 6n+4

The unknown number minus 11 will be expressed as n-11

Finally If Six times a number plus 4 is the same as the number minus 11, them!

6n+4 = n-11

Next is to calculate n;

Collect like terms;

6n-n = -11-4

5n =-15

Divide through by5

5n/5 = -15/5

n = -3

Hence the vale n is -3

Complete question :

Ryan is choosing between two exercise routines. In Routine #1, he burns 22 calories walking. He then runs at a rate that burns 10.5 calories per minute. In Routine #2, he burns 39 calories walking. He then runs at a rate that burns 6.25 calories per minute. For what amounts of time spent running will Routine #1 burn at most as many calories as Routine #2?

Answer:

4 minutes

Step-by-step explanation:

Given the following exercise routines :

Routine #1,

Walking : burns 22 calories walking. He then running : burns 10.5 calories per minute.

Routine #2,

Walking : burns 39 calories walking. He then running : burns 6.25 calories per minute.

Let number of tone spent running = t

Hence,

Routine 1 ; calories burned

22 + 10.5t

Routine 2 ; calories burned

39 + 6.25t

Equating the two equations :

22 + 10.5t = 39 + 6.25t

10.5t - 6.25t = 39 - 22

4.25t = 17

t = 17/4.25

t = 4

Answer:

(−0.25x + 6) + (7.5x + 6.4)= (7.25x+12.4)=19.65

Step-by-step explanation:

19.65 is the answer

If you need the simplified equation it is the following;

7.25x + 12.4

Answer:

we will have to multiply the second equation by 3 to eliminate the y variable by adding.

Step-by-step explanation:

Given the equations

4x – 3y = 6              →   (1)

6x + 2y = 10             →   (2)

As the first equation is multiplied by 2,

2(4x – 3y) = (2)6

8x - 6y = 12               →  (3)

As we have to eliminate y,

so multiply the second equation by 3,

6x + 2y = 10

3(6x + 2y) = 3(10)

18x + 6y = 30              →  (4)

So now adding the new equations (3) and (4) will eliminate the y variable by adding

8x - 6y = 12

18x + 6y = 30

--------------------

26x + 0y = 42

26x = 42

x = 42/26

x = 21/13

Therefore, we will have to multiply the second equation by 3 to eliminate the y variable by adding.

Answer:

260*0.90=sales price=234

Step-by-step explanation:

Step-by-step explanation: We first need to find the discount.

The formula for discount is shown below.

Original Price × Rate of Discount = Discount

So here, the original price is $260 and the

rate of discount is 10% off which we can write as .10.

So we multiply 260 by .20

260 x .10 gives us 26.

So the discount is $26.

Now let's find the sale price.

The formula for sale price is shown below.

Original Price - Discount = Sale Price

Since the original price is $260 ad the discount is $26,

we have 260 - 26 which gives us 234.

So the sale price of the suit is $234.
