alexira [117]

Answer:

10 pounds of potatoes would cost $15.

Step-by-step explanation:

Set up proportion.

4/6=10/x

simplify 4/6 into 2/3,

2/3=10/x

cross product,

2*x=3*10

2x=30

x=30/2

x=15

Answer:

$4(11-y)^{2} -3y^{2}=8$

Step-by-step explanation:

we have

$x+y=11$ ----> equation A

$4x^{2} -3y^{2}=8$ ----> equation B

Solve the system by substitution

step 1

isolate the variable x in the equation A

$x=11-y$ ----> equation A1

step 2

Substitute the equation A1 in the equation B

$4(11-y)^{2} -3y^{2}=8$

Solve for y

Answer:

The correct choice is marked

Step-by-step explanation:

When you end with a true statement, it means any variable value will make the equation true. There are infinite solutions.

When you end with a false statement, it means no value of the variable will make the equation true. There are no solutions.

The correct choice is marked in the image.

A cyclist managed to ride 5 miles against the wind in the same time that it took him to ride 10 miles with the wind. If the wind

bearhunter [10]

Given that the cyclist rides distances of 5 miles and 10 miles due to the wind, the equation that can be used to calculate the speed is therefore;

$\frac{10}{v + 4} = \frac{5}{v - 4}$

<h3>How can the correct equation be found?</h3>

The distance the cyclist rides against the wind = 5 miles

The distance the cyclist rides with the wind = 10 miLes

Let <em>t </em>represent the time it took the cyclist in both directions, we have;

$t = \frac{10}{v + 4} = \frac{5}{v - 4}$

Where;

v = The cyclist's average rate of speed

Which gives;

10 × (v - 4) = 5 × (v - 4)

10v - 40 = 5v - 20

5v = 20

v = 20 ÷ 5 = 5

The equation that can be used to calculate the cyclist's average rate of speed is therefore;

$t = \frac{10}{v + 4} = \frac{5}{v - 4}$
