Answer: x = - 8

Step-by-step explanation:

$\frac{x}{7+x}$ = 8

cross multiplying , we have

8 ( 7 + x) = x

Expanding the Left Hand Side of the equation , we have :

56 + 8x = x collecting the like terms , we have

56 = x - 8x

56 = -7x

dividing through by - 7 we have :

- 8 = x

Therefore :

x = -8

Let r = "I like pancakes," s = "I like syrup," and t = "I like honey." Write this sentence in symbolic form: I like pancakes, an

Rzqust [24]

Answer:

$r\wedge(s\oplus t)$

Step-by-step explanation:

The given statements are

r = "I like pancakes," s = "I like syrup," and t = "I like honey."

Given statement is "I like pancakes, and I like syrup or honey, but not both".

We need to find a symbolic form of the given statement.

If p and q are two statements, then

$p\wedge q$ means p and q are true.

$p\oplus q$ means either p or q are true, but not both.

Using this symbols we can say that,

I like syrup or honey, but not both = $s\oplus t$

I like pancakes, and I like syrup or honey, but not both = $r\wedge(s\oplus t)$

Therefore the required the symbolic form is $r\wedge(s\oplus t)$ .

Answer: <u>96</u> sq ft.

Step-by-step explanation:

First, we will find the area of the rectangular sides. Since the triangle is an equilateral triangle, all the rectangles will be the same size.

A = L * W

A = (10 ft) * (3 ft)

A = 30 ft²

30 ft² * 3 = 90 ft²

Next, we will find the area of the two triangles.

A = $\frac{b*h}{2}$

A = $\frac{3*2}{2}=\frac{6}{2} =3$

3 ft + 3 ft = 6 ft²

Lastly, we will add them together for the total surface area.

90 ft² + 6 ft² = 96 ft²

5x + 4m = 43my + 6 solve for m

pav-90 [236]

9514 1404 393

Answer:

m = (5x -6)/(43y -4)

Step-by-step explanation:

Subtract 4m+6 to separate m-terms from other terms.

5x +4m -(4m +6) = 43my +6 -(4m +6)

5x -6 = 43my -4m

5x -6 = m(43y -4) . . . . factor out m

(5x -6)/(43y -4) = m . . . . divide by the coefficient of m

A group of three friends cycle from Llanfyllin to Vyrnwy at 12 km/h.

garik1379 [7]

The average speed for the journey from Llanfyllin to Bala is 14 km/h

Average speed is the ratio of total distance travelled to total time taken. Also, average speed can be given as the average of the different speeds.

Let d₁ represent the distance from Llanfyllin to Vyrnwy and t represent the time taken, since the speed is 12 km/h, hence:

12 = d₁/t

d₁ = 12t

Let d₂ represent the distance from Vyrnwy to bala and t represent the time taken. Since they spent the same time, since the speed is 16 km/h, hence:

16 = d₂/t

d₂ = 16t

Average speed = total distance/total time

Average speed = (d₁ + d₂) / (t + t)

Average speed = (12t + 16t) / 2t

Average speed = 28t / 2t

Average speed = 14 km/h

Hence their average speed for the journey from Llanfyllin to Bala is 14 km/h.
