Answer:

The store charges $9.77 to ship a hammock that weighs 10.54 pounds.

Step-by-step explanation:

4.50 (shipping cost)

0.50 (per 1 pound)

w = weight in pounds

       w=10.54

4.50+0.50w= total cost

        sub in 10.54 for w

        remember order of operations (PEMDAS)

4.50 + 0.50 (10.54) = 4.50 + 5.27 = 9.77

The store charges $9.77 to ship a hammock that weighs 10.54 pounds.

Answer:

6.5units

Step-by-step explanation:

Find the length side of the smaller square

The area of the square is equal to

A = a^2

so

a^2 = 13

a = √13 units

step 2

Find the length side of the larger square

The area of the square is equal to

A = b^2

so

b^2 = 29.25

b = √29.25 units

step 3

Find the value of x

Applying the Pythagoras Theorem

x^2 = a^2 + b^2

x^2 = 13 + 29.25

x^2 = 42.25 units

x = √42.25

x = 6.5 units

The area of the square adjacent to the third side of the triangle is 85 square units.

Important information:

According to the Pythagoras theorem:

[tex]a^2=b^2+c^2[/tex]

Where, a is hypotenuse and b, c are two legs of a right-angle triangle.

Area of a square is the square of side length. So, [tex]b^2=35[/tex] and [tex]c^2=50[/tex]. Now,

[tex]a^2=35+50[/tex]

[tex]a^2=85[/tex]

Therefore, the area of the square adjacent to the third side of the triangle is 85 square units.

Answer:

The ans is 0.8

Step-by-step explanation:

80% = 0.8 in decimal form.

Percent means 'per 100'. So, 80% means 80 per 100 or simply 80/100.

If you divide 80 by 100, you'll get 0.8 (a decimal number). Read more below on this webpage.

As you can see, to convert from percent to decimal just divide the percent value (80) by 100, and remove the "%" sign.

Answer:

Step-by-step explanation:

x/4-y/2=8, x-2y=32, x=32+2y

x/2+3y/4=-5, 2x+3y=-20, x=(-20-3y)/2

32+2y=(-20-3y)/2

64+4y=-20-3y

7y=-84

y=-12, since x=32+2y

x=32+2(-12), x=32-24=8

Answer:

y = 5 and x = 2

Step-by-step explanation:

Since we have x = -3y + 17, we're going to substitute this equation into the x-value in the second equation.

2(-3y + 17) - y = -1

Multiply the 2 with the terms within the parentheses.

-6y + 34 - y = -1

Add the y values.

-7y + 34 = -1

Subtract 34 from both sides.

-7y = 35

Divide each side by -7.

y = 5

Now that we know the value of y, we can substitute 5 for the y-value in the first equation.

x = -3(5) + 17

Multiply.

x = -15 + 17

Add the two terms together.

x = 2

Answer:

x=18

Step-by-step explanation:

add 2y to both sides 5x=2y+88

subtract 88 from both sides 2y=5x-88

substitute 2y in the second equation for 5x-88

3x+10x-176=58

add like terms 13x-176=58

add 176 both sides

13x=234

x=18

Answer:

( 18, -6.5 )

Step-by-step explanation:

First choose which method you plan on using: Substitution or Elimation. I chose elimination based off preference.  

How to solve using Elimination:

5x -2y = 88  (multiply every number in this equation by two)

3x+4y=58

10x -4y = 176

3x+4y=58      (combine these two equations)

13x = 234  (isolate x by dividing by 13 on both sides)

x = 18         (this is your value for x)

3(18) +4y=58   (plug in for x)

54+4y=28        (solve)

4y = -26            (subtract 54 from both sides)

y = -6.5             (this is y)

write answer in (x, y) format

A function is defined as a relation between a set of inputs having one output each.

The function that would give f(3) = 17 is

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

A function is defined as a relation between a set of inputs having one output each.

We have,

f(3) = 3x + 6

Substitute x = 3

f(3) = 3 x 3 + 6 = 9 + 6 = 15

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

Substitute x = 3

f(3) = 2 ( 3 + 4 ) + 3 = 2 x 7 + 3 = 14 + 3 = 17

f(x) = 5x

Substitute x = 3

f(x) = 5 x 3 = 15

We see that f(x) = 2 ( x + 4 ) + 3 gives the 17 at x =3.

Thus the function that would give f(3) = 17 is

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

For adding, subtracting, and comparing fractions, it is suitable to adjust both fractions to a common (equal, identical) denominator. The common denominator you can calculate as the least common multiple of the both denominators - LCM(12, 3) = 12. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 12 × 3 = 36. In the next intermediate step , cancel by a common factor of 3 gives 3/
