Answer:

x = -1

Step-by-step explanation:

We must solve 7x+2=5x for x.  To do this, subtract 5x from both sides:

2x + 2 = 0, or

2x = -2, or

x = -1

The solution is x = -1.

A classroom board is 54 inches wide and 36 inches tall. Eva
Lady bird [3.3K]
<h3>Answer:  180 inches</h3>

Work Shown:

L = 54 = length

W = 36 = width

P = 2(L+W) ... perimeter of the rectangle

P = 2(54+36)

P = 2(90)

P = 180

She needs 180 inches of ribbon.

To convert to feet, divide by 12. So 180 inches = 180/12 = 15 feet.

aev [14]

THIS IS THE COMPLETE QUESTION

basketball player is shooting a basketball toward the net. The height, in feet, of the ball t seconds after the shot is modeled by the equation h = 6 + 30t – 16t2. Two-tenths of a second after the shot is launched, an opposing player leaps up to block the shot. The height of the shot blocker’s outstretched hands t seconds after he leaps is modeled by the equation h = 9 + 25t – 16t2. If the ball reaches the net 1.7 seconds after the shooter launches it, does the leaping player block the shot?

Yes, exactly 0.6 seconds after the shot is launched.

Yes, between 0.64 seconds and 0.65 seconds after the shot is launched

Yes, between 0.84 seconds and 0.85 seconds after the shot is launched.

No, the shot is not blocked.

Answer:

Yes, between 0.84 seconds and 0.85 seconds after the shot is launched.

Given that the

equation for shot block height h = 9 + 25t – 16t2.

equation for ball height h = 6 + 30t – 16t2.

From the question ,it can be deducted that the shot is made before two tenths of a second or 0.2seconds

Avery is mixing red dye with brown dye to make a maroon dye she needs less than 200 ml of the maroon dye. She wants to mix at le
enot [183]
To answer this item, we let x and y be the amounts (in mL) of the red and the brown dyes, respectively. The equations that would allow us to answer the question are,
                               x + y < 200
                                  
                                    x ≤ 2y
The values of x and y in the inequalities are therefore 133.33 mL and 66.67 mL.
