3x + 2y = 14
3x = 14 - 2y
3x = 12y
3x/3 = 12y/3
x=4y

2x+4y = 12
2x = 12-4y
2x = 10y
2x/2= 10y/2
x=5y

Bananas cost $0.69 per pound. Which equation can be used to model the total cost, C, in dollars, of ,p, pounds of bananas

FromTheMoon [43]

The correct answer would be A. C = 0.69p.
This is the correct answer because the total cost of the bananas should equal 0.69 times each pound bought.
Hope this helped!

Solve the inequality -1/2x -3 ≤ -2.5

IgorLugansk [536]

Answer:

x ≥-1

Step-by-step explanation:

-1/2x -3 ≤ -2.5

Add 3 to each side

-1/2x -3+3 ≤ -2.5+3

-1/2x ≤ .5

Multiply each side by -2, remembering to flip the inequality

-2 * -1/2x ≥ 1/2 * -2

x ≥-1

In isosceles trapezoid JKLM, m∠J = 17x + 7, and m∠M = 11x + 13. Find m∠K.

tensa zangetsu [6.8K]

Answer:

$m\angle K \approx 104.14^{\circ}$

Step-by-step explanation:

In isosceles trapezoid JKLM,

Given: $m\angle J = 17x+7$ and $m\angle M = 11x+13$

Since, JKLM is an isosceles trapezoid so each pair of base angles is congruent.

$m\angle J = m\angle K$

$m\angle M = m\angle L$

As, we know that the sum of the angle of a trapezoid is $360^{\circ}$

The angles are:

$m\angle J = 17x+7$

$m\angle K = 17x+7$

$m\angle L = 11x+13$

$m\angle M = 11x+13$

Therefore,

$17x+7+17x+7+11x+13+11x+13 = 360^{\circ}$

Combine like terms;

$56x + 40 = 360^{\circ}$

Subtract 40 from both sides we get;

$56x + 40 -40 = 360 - 40$

Simplify:

$56x = 320$

Divide both sides by 56 we get;

$x = \frac{320}{56} = \frac{40}{7}$

To find the angle of $m\angle K$ :

$m\angle K = 17x + 7 = 17(\frac{40}{7}) +7 = 97.14 + 7$

Simplify:

$m\angle K \approx 104.14^{\circ}$

Therefore, the value of angle of $m\angle K \approx 104.14^{\circ}$
