olga2289 [7]

Answer:

T > 2.5

Explaination -

t > 2.5

t < 2.5

t > 0.4

t < 0.4

Here it is given that Gallegos burns 236 calories riding her bike each hour.

She wants to burn more than 590 calories riding her bike at the same rate.

Let the time required = t hours

So

236t > 590

⇒ t > 590/236

⇒ t > 2.5

<em>Therefore, the answer is </em> t > 2.5

I need the answers ?
Veseljchak [2.6K]

Answer:

HI=1/2*EF

17-3x=1/2*-9x+37

2(17-3x)=-9x+37

34-6x=-9x+37

-6x+9x=37-34

3x=3

x=3/3

x=1

now substitute the value of HI

17-3x

=17-3*1

=17-3

=14

Step-by-step explanation:

Note :HI=1/2*EF because the straight line joining the mid points of two sides of a triangle is parallel to the third side and equal to half of it.

Find the solution of the square root of the quantity of x plus 2 plus 4 equals 8, and determine if it is an extraneous solution
Iteru [2.4K]

Consider the equation:

\sqrt{x+2}+4 = 8

Subtracting '4' from both the sides of the equation, we get as

\sqrt{x+2}+4-4= 8-4

\sqrt{x+2}= 4

Squaring on both the sides of the equation, we get

(\sqrt{x+2})^2 = (4)^2

x+2 = 16

Subtracting '2' from both the sides of the equation, we get

x+2-2=16-2

x=14

Since, An extraneous solution is a solution that arises from the solving process that is not really a solution at all. But, in this equation x=14 is the solution of the given equation.

Hence, it is not an extraneous solution.
