I'm not sure with this. 4/5 (K+10)=-12 4/5k + 40/5=-12 4/5k+8=-12 4/5k=-8-12 4/5k=-20 4/5k divided by -4/5= -20/-4/5 K=5/5 or 1 is it correct? or 4/5(K+10) = -12 4/5k + 40/5= -12 4/5k= 40/5•-12 4/5k=480/5 K= 24

Solve for k by simplifying both sides of the equation, then isolating the variable.
k = -25

Volunteers at an animal shelter are building a rectangular dog run so that one shorter side of the rectangle is formed by the sh

Shkiper50 [21]

Write and solve a compound inequality to model the possible length of the dog run.

The inequality to model the possible length of the dog run is;. 100 ≤ 2.50x ≥ 200

And the possible length of the dog run is 80ft.

Minimum spending = $100

Maximum spending = $200

Cost per square feet = $2.50

let

x = possible number of square feet

The inequality:

100 ≤ 2.50x ≥ 200

This means possible number of square feet constructed is greater than or equal to $100 or less than or equal to $200

solve:

100 ≤ 2.50x ≥ 200

divide the inequality into 2

100 ≤ 2.50x

x ≤ 100/2.5

x ≤ 40

the other part:

2.50x ≥ 200

x ≥ 200/2.50

x ≥ 80

Therefore,

the possible length of the dog run is 80 feet

On Naomi's cell phone plan, the amount she pays each month for international text messages is proportional to the number of inte

Margaret [11]

A) The constant of proportionality in this proportional relationship is $k = \frac{y}{x}$

B) The equation to represent this proportional relationship is y = 0.2x

Solution:

Given that,

The amount Naomi pays each month for international text messages is proportional to the number of international texts she sends that month

Therefore,

This is a direct variation proportion

$\text{ amount paid each month } \propto \text{ number of international texts sent that month}$

Let "y" be the amount that Naomi pays each month

Let "x" be the number of international texts she sends that month

Therefore,

$y \propto x$

y = kx -------- eqn 1

Where, "k" is the constant of proportionality

Thus the constant of proportionality in this proportional relationship is:

$k = \frac{y}{x}$

Last month, she paid $3.20 for 16 international texts

Therefore,

y = 3.20

x = 16

Thus from eqn 1,

$3.20 = k \times 16\\\\k = \frac{3.20}{16}\\\\k = 0.2$

Substitute k = 0.2 in eqn 1

y = 0.2x

The equation would then be y = 0.2x
