mjcaela and julia each improved their yards by planting daylilies and shrubs. they bought their supplies from the same store. mi

Answer:

The cost of one day lily = $ 11,

The cost of one shrub = $ 2.

Step-by-step explanation:

Let x be the cost of one day lily and b be the cost of one shrub,

Michaela spent $148 in 12 day lilies and 8 shrubs.

⇒ 12 x + 8 y = 148

⇒ 3 x + 2 y = 37 ----------(1)

While, Julia spent $92 on 6 day lilies and 13 shrubs.

⇒ 6 x + 13 y = 92 --------(2)

2 × Equation (1),

⇒ 6 x + 4 y = 74 --------(3)

Equation (2) - Equation (3),

9 y = 18

⇒ y = 2

By substituting this value in equation (1),

⇒ 3 x + 4 = 37

⇒ 3 x = 33

⇒ x = 11

Hence, the cost of one day lily = x = $ 11

And, the cost of one shrub = y = $ 2

Solve the inequality of -2/3 > z/5

patriot [66]

Answer:

$\boxed{\bold{Z < \frac{-10}{3} }}$

Explanation:

Simplify both sides of inequality

-2 / 3 > 1 / 5 z

Flip equation

1 / 5 z < -2 / 3

Multiply both sides by 5

(1 / 5 z) 5 < (-2 / 3) 5

Z < -10 / 3

Find an equation of variation in which y varies jointly as x and z and inversely as the product of w and p,

pentagon [3]

The equation of variation in which y varies jointly as x and z and inversely as the product of w and p is y=0.5(xz/wp).

Given that variable y varies jointly as x and z and inversely as the product of w and p,where y=7/28 where x=7,z=4,w=7 and p=8.

We are required to find the equation of variation.

To solve this problem we must apply the following procedure:

1) We have that y varies jointly as x and z and inversely as the product of w and p. Therefore we can write the following equation,where k is the constant of proportionality:

y=k(xz/wp)----------1

Now we have to solve for the constant of proportionality as done under:

k=ywp/xz-------------2

Using the values in equation 1.

k=(7/28)(7)(8)/(7)(4)

=0.5

Using all the values in the equation 2.

y=0.5(xz/wp)

Hence the equation of variance is y=0.5(xz/wp).

Question is incomplete.The following values should be included:

y=7/28 where x=7,z=4,w=7 and p=8.

Walking briskly consumes 250 calories in 1 hour. How long would you have to walk briskly to lose 3 pounds?

Furkat [3]

Answer:

42 hours

Step-by-step explanation:

1 pound = 3,500

3,500 × 3 = 10,500

1 hour = 250

10,500 ÷ 250 = 42

42 hours
