Answer:
x = 2
Step-by-step explanation:
12/7.5 = 1.6
x+6/2x+1 = 1.6
to find the value of x :
![\frac{x+6}{2x+1} = \frac{1.6}{1}](https://tex.z-dn.net/?f=%5Cfrac%7Bx%2B6%7D%7B2x%2B1%7D%20%3D%20%5Cfrac%7B1.6%7D%7B1%7D)
x + 6 = 3.2x + 1.6
x - 3.2x = 1.6 - 6
- 2.2x = - 4.4
- x = - 4.4/2.2
- x = - 2
x = 2
Answer:
For this case we have the following quadratic equation:
Where,
t: time
s: height of the ball
By the time the height is 20 feet we have:
Rewriting the polynomial we have:
Using the quadratic formula we have:
Substituting values we have:
Doing the calculations we have the roots are:
Answer:
the time when the football will be 20ft above the ground is:
B) 0.73 seconds or 1.46 seconds
Step-by-step explanation:
Answer:
P = 2l + 2w
solve for w
re-write
2l + 2w = P
subtract 2l from both sides
2w = P - 2l
divide both sides by 2
w = (P - 2l) / 2
Answer is B
w = (P - 2l) / 2
Start with 6x + 2y = 15. Then subtract 6x + 2y from both sides. The left side of your equation then becomes 0 and the right side 15 - 6x - 2y.
Answer:
m<B= 52
Step-by-step explanation:
2x - 30 + 3x + 10 + 7x + 32 = 180
12x + 12 = 180
12x = 168
x = 14
m<B= 3x + 10
3(14) + 10
52
