Answer:

28 $\sqrt{6}$

Step-by-step explanation:

Using the rule of radicals

$\sqrt{a}$ × $\sqrt{b}$ ⇔ $\sqrt{ab}$

$\sqrt{96}$

= $\sqrt{16(6)}$

= $\sqrt{16}$ × $\sqrt{6}$

= 4 $\sqrt{6}$

Then

7 $\sqrt{96}$

= 7 × 4 $\sqrt{6}$

= 28 $\sqrt{6}$

The table can be used to determine the solution to the system of equations, 2y − x = 8, and y − 2x = −5. Which solution can be u

SIZIF [17.4K]

The answer is (6, 7)

This is the system of two equations:
<span>2y − x = 8
y − 2x = −5
_____
Express the second equation in the term of y:
2y - x = 8
y = 2x - 5
_____
Substitute y in the first equation:
2(2x - 5) - x = 8
4x - 10 - x = 8
4x - x = 10 + 8
3x = 18
x = 18/3
x = 6

Since x = 6 and y = 2x - 5, then:
y = 2 * 6 - 5
y = 12 - 5
y = 7

Therefore, (x, y) = (6, 7)</span>

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!
