Answer:

The traveller's speed is 5ft/s and the walkway speed is 3ft/s

Step-by-step explanation:

Given

Represent the traveller's speed with T and the walkway's speed with W.

When the traveller walk against the walkway, we have:

[tex]T - W = 2[/tex] ---- i.e. 2ft/s against the walkway

When the traveller walk with the walkway, we have:

[tex]T + W = 8[/tex] ---- i.e. 8ft/s with the walkway

Required

Solve for W and T

[tex]T - W = 2[/tex] --- (i)

[tex]T + W = 8[/tex] --- (ii)

Add (i) and (ii)

[tex]T + T - W + W = 2 + 8[/tex]

[tex]T + T = 2 + 8[/tex]

[tex]2T = 10[/tex]

Divide both sides by 2

[tex]\frac{2T}{2} = \frac{10}{2}[/tex]

[tex]T = \frac{10}{2}[/tex]

[tex]T = 5[/tex]

Substitute 5 for T in (ii)

[tex]T + W = 8[/tex]

[tex]5 + W = 8[/tex]

Make W the subject

[tex]W = 8 - 5[/tex]

[tex]W = 3[/tex]

Hence, the traveller's speed is 5ft/s and the walkway speed is 3ft/s

Answer:

x=-2,y=2

Step-by-step explanation:

2x+y=-2 ----> y=-2-2x----(1)

25x+3y=-4 ---(2)

Replace (1) in (2)

5x+3(-2-2x)=-4

5x-6-6x=-4

-x=-4+6

-x=2

x=-2

If x=-2,then replace x in (1)

y=-2-2(-2)

y=-2+4=2

Answer:

x^-(3/2) which is (1)

Step-by-step explanation:

squared root of x³ is basically x^(3/2)

And if the question is 1/x^(3/2), then you can simply answer x^-(3/2) which is (1)

1 1/2 cups of flour = 12/8 cups of flour

2 2/3 cups of oatmeal = 2 2/3 cups of oatmeal

1 cup sugar = 3/3 or 8/8 cups of sugar

1/2 cup of brown sugar = 4/8 cups of brown sugar

Answer:

c) 160,000

Step-by-step explanation:

Since we know that the population of both city x and city y are equal in 2015, we can use the population growth of population of city x to find the population in 2015:

120,000 x 1.2 = 144,000.

Now, since we know that City Y's population decreased 10% from 2010 to 2015, we can divide the 2015 population of city Y (which is the same as city x - 144,00) by 1 - decrease rate to find city y's population in 2010:

1 - .1 = .9

144,000 / .9 = 160,000

I hope this helps!

Answer:

108 is your correct answer

Step-by-step explanation:

Answer:

6 miles in 90 minutes

Step-by-step explanation:

Since wendy is walking at a fair constant rate, you would multiply 3x30 to get 90 minutes and you will multiply 2x3 to get 6 miles

Answer:

6 miles

Step-by-step explanation:

90 divide by 30= 3

3*2 =6

Answer:

1 ( 12-3m ) - 5m ( 11-4m+25)

1 ( 9m ) - 5m ( 32m )

9m -5m ( 32m )

4m ( 32m )

32×4 = 128 m

128 m

Answer:

Without an equivalence given (i.e. an equals sign somewhere in the expression), we have no way of solving for m.

We can however simplify it:

m²(2 - 3m) - 6m(1 - 4m + 5m²)

= 2m² + 3m³- 6m + 24m² - 30m⁴

= 26m² + 3m³ - 6m - 30m⁴

= m(-30m³ + 3m² + 26m - 6)

Answer:

x = 12

Step-by-step explanation:

DE + EF = DF

2x - 1 + 5x - 13 = 70

7x - 14 = 70

7x = 70 + 14

    = 84

x = 84 ÷ 7

x = 12

Answer: x=12

Step-by-step explanation:

2x-1+5x-13=70

Combine like terms

7x-14=70

Add 14 to both sides

7x=84

Divide both sides by 7

X=12

Answer:

a) 5,5kg

b) 8,65 €

Step-by-step explanation:

Daniela ha comprado 2,5 kg de naranjas a un precio de 1,75 € el kg, 1,5 kg de manzanas a 1,6 el kg y 1,5 kg de plátanos a 1,25 € el kg.

a) Si ponemos toda la fruta en la misma bolsa, ¿cuál es su peso?

Naranjas = 2,5 kg

Manzanas = 1,5 kg

Plátanos = 1,5 kg

Por lo tanto:

El peso total

= Peso de las naranjas + Peso de las manzanas + Peso de las bananas

= 2,5 kg + 1,5 kg + 1,5 kg

= 5,5 kg

b) ¿Cuánto ha pagado Daniela por toda la fruta?

Costo de las naranjas

Daniela ha comprado 2,5 kg de naranjas a un precio de 1,75 € el kg

1 kg = 1,75 €

2,5 kg = x

x = 2,5 × 1,75 €

x = 4,375 €

Costo de las manzanas

1,5 kg de manzanas a 1,6 € el kg

1 kg = 1,6 €

1,5 kg = x

Cruz multiplicar

x = 1,5 × 1,6 €

x = 2,4 €

Costo de los plátanos

1,5 kg de plátanos a 1,25 € el kg.

1 kg = 1,25 €

1,5 kg = x

Cruz multiplicar

x = 1,5 × 1,25 €

x = 1.875 €

La cantidad que Daniela pagó por toda la fruta es:

4,375 € + 2,4 € + 1,875 €

= 8,65 €

Answer:

15 feet

Step-by-step explanation:

Michele wanted to measure the height of her school's flagpole to place on the ground 35 ft from the flagpole then walks backwards until she was able to see the top of the pole in the mirror her eyes were 5 feet above the ground and she was 12 ft away from the mirror using similar triangles, find the height of the flagpole to the nearest of a foot

Using similar triangles

= Let the height of the flagpole be represented as h.

h/35 =5/12

We cross Multiply

35 x 5 = 12h

12h = 175

h = 175/12

h = 14.583333333 feet

Approximately to the nearest foot is

h = 15 feet

Answer:

15°C

Step-by-step explanation:

Find the difference by subtracting -4.8 from 10.2

10.2 - (-4.8)

Subtracting a negative number changes to adding a positive number:

10.2 + 4.8

= 15

So, the difference in temperature between the two cities is 15°C

Answer:

See below

Step-by-step explanation:

There are two ways to graph an equation.

1st Way:

We can use a graphing calculator. (See the attached file)

2nd Way:

We can take the values of x as 0, 1 , 2 (Or anything).

Then, We have to put the values of x in the equation to get the value of y accordingly.

According to these values, Plot the graph.

Also,

Slope = 5 / 6

y-intercept = 1

Step-by-step explanation:

Answer:

AB is undefined, CD is y = -5

Step-by-step explanation:

Find both of the line's slopes. You can use the formula for slope to calculate this answer because you know two points on the line for both lines (Look below). If you plug in the points for AB, you would have ( -2 - 7)/0, which would be undefined, because anything divided by 0 is undefined. Since the slope for AB is undefined, it is undefined. Next, we have CD. If you plug in the points for CD, you would get (-5 - (-5))/(6 - 3), which would be 0/3, which is 0. This means that the slope is 0. Next, we have to plug in the points for CD into the formula for equation of the line (Look Below), which would be y - (-5) = 0 * (x - 6), which simplifies to y + 5 = 0, which is y = -5.

Formula for Slope:

[tex]\frac{y1 - y2}{x1 - x2}[/tex]

Usable with 2 points of the line given ((x1, y1) and (x2, y2))

Formula for Equation of the Line:

[tex]y - y1 = slope * (x - x1)[/tex]

Usable with the slope and a point given ((x1, y1))

Answer: AB is undefined (AB is not a relationship, slope is undefined (Vertical Line)) and CD is y = -5 (Horizontal Line)
