Solve the y for the equation 5x-2y=10

eduard

Answer:

y = 5/2x - 5

Step-by-step explanation:

Step 1: Write equation

5x - 2y = 10

Step 2: Solve for <em>x</em>

Subtract 5x on both sides: -2y = 10 - 5x
Divide both sides by -2: y = -5 + 5/2x
Rewrite: y = 5/2x - 5

Softa [21]

Answer:

$10\sqrt{14})+8\sqrt{21})+30\sqrt{3}+36\sqrt{2})$

Step-by-step explanation:

The given product is:

$(2\sqrt{7}+3\sqrt{6})(5\sqrt{2}+4\sqrt{3})$

We expand using the distributive property to get;

$(2\sqrt{7})(5\sqrt{2}+4\sqrt{3})+3\sqrt{6}(5\sqrt{2}+4\sqrt{3})$

Simplify:

$=10\sqrt{14})+8\sqrt{21})+15\sqrt{12}+12\sqrt{18})$

$=10\sqrt{14})+8\sqrt{21})+30\sqrt{3}+36\sqrt{2})$
