Answer:

GQ = 25

Step-by-step explanation:

Given that Q is the midpoint of GH , then

GQ = QH = 2x + 3 and

GH = GQ + QH, that is

5x - 5 = 2x + 3 + 2x + 3

5x - 5 = 4x + 6 ( subtract 4x from both sides )

x - 5 = 6 ( add 5 to both sides )

x = 11

Thus

GQ = 2x + 3 = 2(11) + 3 = 22 + 3 = 25

Answer:

25 units

Step-by-step explanation:

GH = 2GQ

5x - 5 = 2(2x + 3)

5x - 5 = 4x + 6

x = 11

GQ = 2(11) + 3 = 25

90 POINT QUESTION!!!
Aleks [24]

Answer: 9.19 ft

Step-by-step explanation:

Hi, since the situation forms a right triangle (see attachment) we have to apply the next trigonometric function.  

Sin α = opposite side / hypotenuse  

Where α is the angle of elevation of the ladder to the ground, the hypotenuse is the longest side of the triangle (in this case is the length of the ladder), and the opposite side (x) is the height of the top of the ladder above the ground.

Replacing with the values given:  

Sin 45 = x/ 13

Solving for x  

sin45 (13) =x  

x= 9.19 ft

Feel free to ask for more if needed or if you did not understand something.

Which choice shows the result of substituting 3x – 5 into the second equation for y?
ahrayia [7]

Answer:  The answer is (B) 2x + 3(3x – 5) = 51 .

Step-by-step explanation:  We are given three options and we are to select which choice shows the result of substituting 3x – 5 into the second equation for y.

So, y = 3x - 5.

Since the standard form of a linear equation i two variables is ax + by = c, so the second equation as given in the options must be of the form 2x + 3y = 51.

If we substitute y = 3x - 5, then this equation becomes

2x + 3(3x - 5) = 51.

Thus, (B) 2x + 3(3x – 5) = 51  is the correct option.

CALC!! Please help me. For which pair of functions f(x) and g(x) below will the limit as x goes to infinity of the product of f
Marizza181 [45]
First limit:
\lim_{x\to\infty}(10x+e^{-x})*\frac{1}{5x}
=\lim_{x\to\infty}(2+\frac{1}{5xe^{x}})
=2+0
=2

Since we know that the first pair of functions does not approach 0, we do not have to check the others.

antoniya [11.8K]

answer= x=20

Step-by-step explanation:

We have, 35% × x = 7

or,  

35

100

× x = 7

Multiplying both sides by 100 and dividing both sides by 35,

we have x = 7 ×  

100

35

x = 20

If you are using a calculator, simply enter 7×100÷35, which will give you the answer.
