Show all of your work. Simplify the expression: 4(3x + 2) + 5x​

Answer:

y = 3x - 2

3x - y = 2

y = 2(x + 3)

Step-by-step explanation:

y = the larger number

x = the smaller number

A larger number is double the sum of 3 and a smaller number

y = 2(x + 3)

y = 6 + 2x

The larger number is 2 less than 3 times the smaller number.

y = 3x - 2

Make -2 the subject

y - 3x = -2

Make 2 the subject

y = 3x - 2

y - 3x = -2

(y - 3x) * -1 = -2 * -1

-y + 3x = 2

3x - y = 2

The answers:

y = 3x - 2

3x - y = 2

y = 2(x + 3)

The value of expression after subtraction is,

⇒ - 0.177

Subtraction in mathematics means that is taking something away from a group or number of objects. When you subtract, what is left in the group becomes less.

Given that;

Expression is,

⇒ 0.123 - 0.3

Now, We can simplify the expression by subtracting as;

⇒ 0.123 - 0.3

⇒ - 0.177

Thus,  The value of expression after subtraction is,

⇒ - 0.177

Answer:

The famous irrational numbers consist of Pi, Euler's number, Golden ratio. Many square roots and cube roots numbers are also irrational, but not all of them. For example, √3 is an irrational number but √4 is a rational number. Because 4 is a perfect square, such as 4 = 2 x 2 and √4 = 2, which is a rational number.

Answer:

A = 2512 cm²

Step-by-step explanation:

The surface area of a sphere is A = 2πr².  With d = 40 cm, r = 20 cm, and so the surface area of this sphere is A = 2(3.14)(20 cm)², which works out to  A = 2512 cm²

Answer:

(x,y)=(4,6)

Step-by-step explanation:

3x+4y=36

y=-1/2 x+8

step 1: substitute the value of y

[tex]3x+4(-\frac{1}{2}x+8)=36[/tex]

step 2: solve equation for x

[tex]3x+4(-\frac{1}{2}x+8)=36[/tex]

3x-2x+32=36

x+32=36

x=36-32

x=4

step 3: substitute the value of x

[tex]y=-\frac{1}{2} (4)+8[/tex]

Step 4: solve equation for y

[tex]y=-\frac{1}{2} (4)+8[/tex]

y=-2+8

y=6

there for the answer is

(x,y)=(4,6)

Answer:

1. 1+4 = 5in^2

2. 1+6 = 7cm^2

3. 8+4 = 12ft^2

Answer:

The starting height of the raiders is 39 meters.

Step-by-step explanation:

Physically speaking, a free fall motion is an uniformly accelerated motion due to gravity. Mathematically, speaking the equation of motion for the height of an object under free fall is a second order polynomial (quadratic function).

Let [tex]h(t) = -9.8\cdot t^{2}-5\cdot t + 39[/tex] be the height of the riders, in meters, the starting height is the height evaluated at [tex]t = 0\,s.[/tex] Hence, we proceed to the determined the required data by direct evaluation:

[tex]h(0) = -9.8\cdot (0)^{2}-5\cdot (0) +39[/tex]

[tex]h(0) = 39[/tex]

The starting height of the raiders is 39 meters above the ground.

Find where the curve intersects the x-axis; this happens when y = 0:

y = t - t ² = 0   →   t (1 - t ) = 0   →   t = 0, t = 1

Then the area of the bounded region is

[tex]\displaystyle\int_0^1 y(t) x'(t)\,\mathrm dt=\int_0^1 (t-t^2)e^t\,\mathrm dt=\boxed{3-e}[/tex]

(you can compute the integral by parts)

Answer:

k=1/4

Step-by-step explanation:

x² - 5kx+ k=0  ....(1)

suppose 2 roots: a and 4a

(x-a)(x-4a)=0

x² - 5ax + 4a² = 0 ....(2)

compare (1) and (2): -5a = -5k              a=k

4a² = k                4a² = a   (substitute)

a(4a-1) = 0

a = 0 or a = 1/4        (if a=0   k=0 and x=0 is not the solution)

a = 1/4      k = 1/4

(a₂ = 1/4 * 4 = 1)

Answer:

k = 1/4.

Step-by-step explanation:

Let the roots be  r and 4r   and using the fact that sum of the roots = -b/a and product = a/c, we have:

r + 4r = -(-5k)

r*4r = k

5r = 5k

4r^2 = k

From the 3rd equation:

r = k, therefore:

4k^2 = k

4k = 1

k = 1/4.

Answer: $48.24

Step-by-step explanation:

Since the total cost of the meal ate by Molly and her friends was $96.15 and they used a coupon for 20% off, paid 8.5% tax and left a 22% tip, the total amount paid will be:

= $96.15 + (20% × $96.15) + (8.5% × $96.15) + (22% × $96.15)

= $96.15 + $19.23 + $8.17275 + $21.153

= $144.70575

= $144.71

Since there are three friends, the amount that each person will pay will be:

= $144.71 / 3

= $48.24

Step-by-step explanation:

Cost of shoes = $39.95

Cost per pair of socks = $1.99

Number of socks pairs purchased = x

Total amout spent = (cost of shoes + cost of x pairs of socks)

Cost of x pairs of socks = $1.99 * x = $1.99x

Total amount spent = $39.95 + $1.99x
