What times what equals -30 but also can be added together and equal -4
Step2247 [10]

Answer:

Step-by-step explanation:

xy=-30

y=-30/x

x+y=-4

x-30/x=-4

x²-30=-4x

x²+4x-30=0

x^2+4x-30=0\\x=\frac{-4\pm\sqrt{16+120} }{2} \\=\frac{-4\pm\sqrt{136} }{2} \\=-2\pm\sqrt{39} \\=-2+\sqrt{39} ,-2-\sqrt{39} \\y=\frac{-4}{-2+\sqrt{39} } ,\frac{4}{2+\sqrt{39} }correction write ~-30 ~in~place~of~-4~in~the~end

Mike jogged a total distance of 5 1/3 miles during the months of October and November. If Mike only jogger 1/6 mile every day, W
Bumek [7]

Answer:

D

Step-by-step explanation:

If he jogged x miles every day, and he jogged a total distance of y miles, then he runs for y/x days. This is an extension of the d=rt or distance equals rate times time.

We plug in for y and x to get that he runs for 5~1/3~~/~~1/6.

So, the answer is \boxed{D} and we're done!

13x + 15=17x-13 solve for the solution
Archy [21]

Answer: x=7

Step-by-step explanation:

Step 1: Subtract 17x from both sides.

13x+15−17x=17x−13−17x

−4x+15=−13

Step 2: Subtract 15 from both sides.

−4x+15−15=−13−15

−4x=−28

Step 3: Divide both sides by -4.

−4x/−4 =−28/−4

x=7
