Answer:

18 miles

Step-by-step explanation:

Find how many miles he walked this week by multiplying 2 by 6:

2(6)

= 12

Add this to 6, since he walked 6 miles last week:

12 + 6

= 18

So, in all, he will have walked 18 miles

Answer:

x = 3.6

Step-by-step explanation:

Since, ABCD ~ EFGH

Therefore, all interior angles of both the quadrilaterals will be equal and the corresponding sides of both quadrilaterals will be proportional.

[tex]\frac{AD}{EH}=\frac{AB}{EF}[/tex]

[tex]\frac{x}{2.4}=\frac{3}{2}[/tex]

x = [tex]\frac{3\times 2.4}{2}[/tex]

x = 3.6

Answer:

Jeans: 3 T-shirts: 2

Step-by-step explanation:

40 times 3 equals 120

20 times 2 equals 40

120+40=160

Joe bought 3 pairs of jeans and 2 T-shirts.

The equation is defined as a mathematical statement that has a minimum of two terms containing variables or numbers that are equal.

Let's represent the number of pairs of jeans that Joe bought "x".

The total cost of the jeans would be $40 × x.

And the total cost of the T-shirts would be $20 × (5 - x).

Since Joe spent a total of $160, we can set up an equation to solve for x:

$40 × x + $20 × (5 - x) = $160

Expanding the second term:

$40 × x + $20 × 5 - $20 × x = $160

Combining like terms:

$40 × x + $100 - $20 × x = $160

Subtracting $100 from both sides:

$40 × x - $20 × x = $60

Combining like terms:

$20 x = $60

Dividing both sides by $20:

x = 3

So he bought 3 pairs of jeans and 5 - 3 = 2 T-shirts.

Answer:

y = 2x + 4

Step-by-step explanation:

Figure out the slope.

y2 - y1 / x2 - x1       8 - 6/ 2 - 1 = 2

Find out the y-intercept. Your equation so far is y = 2x + b.

8 = 2(2) + b

8 = 4 + b

4 = b

The resulting expression will be [tex]\frac{x+2}{x-3}\\[/tex]

Given the expression as shown in the question:

[tex]\frac{x-2}{x+3} + \frac{10x}{x^2-9}[/tex]

Find the LCM of the expression to have:

[tex]\frac{(x-2)(x-3)+10x}{(x+3)(x-3)}[/tex]

Expand the expression

[tex]\frac{(x^2 - 5x+6+10x}{(x+3)(x-3)}\\\frac {x^2 + 5x+6}{(x+3)(x-3)}\\[/tex]

Expand the expression

[tex]=\frac {x^2 + 2x + 3x +6}{(x+3)(x-3)}\\=\frac {x(x + 2) + 3(x +2)}{(x+3)(x-3)}\\=\frac{(x+2)(x+3)}{(x+3)(x-3)}\\ =\frac{x+2}{x-3}\\[/tex]

Hence the resulting expression will be [tex]\frac{x+2}{x-3}\\[/tex]

Answer:

About 31 years

Step-by-step explanation:

Given data

Principal= $3500

Rate=  4.75%

Final amount= $15,000

Time=??

The expression for time on compound interest is

Calculate time, solve for t

t = ln(A/P) / r

substitute

Calculate time, solve for t

t = ln(15000/3500) / 0.0475

t= ln(4.2857)/ 0.0475

t= 1.4552/0.0475

t= 30.63 years

Hence it will take about 31 years

A = {3 , 6 , 9}

B = {2,3,5,7}

A ∪ B = { 2,3,5,6,7,9}

(A∪B)' - is set of all elements in universal set  that are not in (A∪B)

Answer:

[tex]b = l\times w[/tex] to guarantee that both formulas are the same.

Step-by-step explanation:

Dimensionally speaking, the volume is the cube of length. By direct comparison, we find that [tex]l,w,h[/tex] have length units, whereas [tex]b[/tex] have area unit, that is, the square of length.

Hence, [tex]b = l\times w[/tex] to guarantee that both formulas are the same.

Answer:

You need to rent

14

videos, and you'll pay the same amount for both. Renting

Explanation:

We can create an equation. Say the number of videos you rent is given by

n

n

videos without membership, we'll have to pay

4

n

. If we rent the same amount of videos with membership, we'll have to pay

21

To find the value of

n

such that the amount you pay without membership is equal to the amount you pay with, we write:
