Answer:

[tex]y=\frac{5+8x}{10} , x=x[/tex]

Step-by-step explanation:

y-0.8x=0.5

y*10-0.8x*10=0.5*10

10y-8x=5

10y-8x+8x=5+8x

10y/10=5/10+8x/10

y=5+8x/10

5*5+8x/10-2.5

8x+5/2-2.5=4x

y=5+8x/10, x=x

Answer:

x = 5

Step-by-step explanation:

5x = 2 + 23

5x = 25

x = 5

Step-by-step explanation:

Answer:

B. -3

Step-by-step explanation:

f(x) = 3x - 15

f(4) means x=4, so you want to plug 4 into the equation.

f(4) = 3(4) - 15

f(4) = 12 - 15

f(4) = -3

Answer:

B

Step-by-step explanation:

f(4) has the same meaning (for this question ) as x = 4

Let x = 4

f(4) = 3*4 - 15

f(4) = 12 - 15

f(4) = - 3

Answer:

The rate of the current is 2 mph.

Step-by-step explanation:

When the boat travels upstream we have:

[tex] v_{T_{1}} = v_{b} - v_{c} [/tex]                      

[tex] \frac{x_{1}}{t_{1}} = v_{b} - v_{c} [/tex]    

Where:

[tex] v_{T}[/tex]: is the total speed

[tex]v_{b}[/tex]: is the speed of the boat = 10 mph

[tex]v_{c}[/tex]: is the speed of the current

x: is the distance

t: is the time

And when the boat travel downstream we have:

[tex]v_{T_{2}} = v_{b} + v_{c}[/tex]        

[tex] \frac{x_{2}}{t_{2}} = v_{b} + v_{c} [/tex]                              

Since the boat takes 4 hours longer to travel 48 miles going upstream than it does to travel 24 miles going downstream we have:

[tex] \frac{x_{1}}{t + 4} = v_{b} - v_{c} [/tex]   (1)

[tex] \frac{x_{2}}{t} = v_{b} + v_{c} [/tex]   (2)

By adding equation (1) with (2):

[tex] \frac{x_{1}}{t + 4} + \frac{x_{2}}{t} = 2v_{b} [/tex]

[tex] tx_{1} + (t+4)x_{2} - 2v_{b}t(t+4) = 0 [/tex]

[tex] 48t + 24(t+4) - 2*10t(t+4) = 0 [/tex]

By solving the above equation for t we have:

t = 2 h      

Now, by entering "t" into equation (2) we have:

[tex] \frac{24 miles}{2 h} = 10 mph + v_{c} [/tex]  

[tex] v_{c} = 2 mph [/tex]

Therefore, the rate of the current is 2 mph.

I hope it helps you!  

Answer:

La medida del primer ángulo es 30°, la medida del segundo ángulo es 50° y  el tercer ángulo mide 100°.

Step-by-step explanation:

Siendo "x" el valor de un ángulo del triángulo obtusángulo, sabes que uno de los ángulos, llamado segundo ángulo, mide 20° más que el primero. Este segundo ángulo se representa como x + 20°.

Además, un tercer ángulo mide el doble que el mayor de los dos, que en este caso es el ángulo cuya expresión es x + 20°. Por lo que el doble de este será 2*(x + 20)°, que será la medida del tercer ángulo.

Teniendo en cuenta que la suma de los ángulos interiores de un triángulo es 180°. Entonces, es posible sumar los valores de cada uno de los ángulos e igualarlos a 180°:

x + x + 20° + 2*(x + 20°) = 180°

Resolviendo:

x + x + 20° + 2*x + 2*20° = 180°

x + x + 20° + 2*x + 40° = 180°

4*x + 20° + 40° = 180°

4*x + 60° = 180°

4*x = 180° - 60°

4*x = 120°

x = 120° ÷ 4

x = 30°

Entonces, la medida del primer ángulo es 30°. El segundo ángulo es calculado como x + 20° = 30° + 20° = 50° mientras que  el tercer ángulo es 2*(x + 20°) = 2*(30° + 20°) = 2*(50°) = 100°

La medida del primer ángulo es 30°, la medida del segundo ángulo es 50° y  el tercer ángulo mide 100°.

the answer would be 100

Step-by-step explanation:

55+45=100 because all yout have to do is add angle A and angle B together

Answer:

a)  x=24/k

b)  x=24/3

    x=8

Step-by-step explanation:

Quotient meant division and you are trying to find the quotient (x) so you divide 24 by 3 to get 8

52 1/2 OR 52.5

Step-by-step explanation:

You divide 630 by the number of months in a year, 12. 630 / 12 = 52.5. So the answer is 52.5 (Dollars, cents, whatever money label it is).

Answer:

y = 4x + 12

Step-by-step explanation:

slope-intercept form is y = mx + b, where m = slope and b = y-intercept.

since you're given the values for m and b, all you need to do is plug those into the equation for slope-intercept form.

plug in 4 for m.

y = mx + b ⇒ y = 4x + b

plug in 12 for b.

y = 4x + b ⇒ y = 4x + 12

it doesn't matter which one you plug in first as long as you plug the value in for the correct variable.

the equation of your line in slope-intercept form is y = 4x + 12. i hope this helps! have a great day <3

Answer:

The answer is 3 1/3.

Step-by-step explanation:

To find this answer, divide 5/4 by 3/8.

(5/4) / (3/8) = 5/4 * 8/3 = 40/12 = 10/3 or 3 and 1/3.

Proof:

10/3 * 3/8 = 30/24 = 5/4

Answer:

Jane traveled 8 miles farther then her trainer

Step-by-step explanation:

The Pythagora's Theorem

In any right triangle, the square of the measure of the hypotenuse is the sum of the squares of the legs. This can be expressed with the formula:

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

Where

c = Hypotenuse or largest side

a,b = Legs or shorter sides

Jane's path from the Health Club to the end of her route describes two sides of a right triangle of lengths a=16 miles and b=12 miles.

Her total distance traveled is 16 + 12 = 28 miles

Her trainer goes directly from the Health Club to meet her through the hypotenuse of the triangle formed in the path.

We can calculate the length of his route as:

[tex]c=\sqrt{16^2+12^2}[/tex]

[tex]c=\sqrt{256+144}=\sqrt{400}=20[/tex]

c = 20 miles

The difference between their traveled lengths is 28 - 20 = 8 miles

Jane traveled 8 miles farther then her trainer
