Answer:

2.50(10) + 3x = 135.97, x = 38.66

Step-by-step explanation:

This should be pretty simple.

Basically, we know that he bought 10 pairs for 2.50 so that's $25 right there.

Our total is 135.97 though-

so here, we take our total from the right side of the equation, and subtract 25 from that.

135.97 - 25 = 115.97

Since he bought three pairs, divide it by 3.

115.97 / 3 = 38.66

One pair of shoes costs $38.66 - hope this helps!

How do you get 2 square root of 2 from 4​
balandron [24]

Answer:

2 x 2 = 4

Step-by-step explanation:

If you're trying to find the square root of say, 9, it would be 3 x 3 and your trying to find a square root something it's just something multiplied by itself again. such as the square root 1225 is 35 x 35, because 35 x 35 is 1225. Sorry if this is to complicated for you I learnt this in first term and I found it easy to grasp because of the way my math teacher taught it.

Sorry in advance ¯\_(⸟‸⸟)_/¯

Solve 6y2-5y-6 = 0 using the quadratic formula.
sergejj [24]

Answer:

Ay=3 over 2 or y=-2 over 3

Step-by-step explanation:

the quadratic formula: y={-b±√(b²-4ac)}/2a

In the equation 6y²-5y-6= 0, a=6, b=-5, c= -6

Substituting for the values in the formula we get:

{-(-5)±√[(-5²)-4(6)(-6)}/2(6)

{5±√169}12

={5±13}/12

(5+13)/12=3/2 or (5-13)/12= -2/3
