Answer:
Step-by-step explanation:
t + u = 11 ----------- (1 )
10t + u = 10u + t - 9
10t + u - 10u - t = -9
10t - t + u - 10u = - 9
Combine like terms
9t - 9u = -9
Divide the entire equation by 9
t - u = -1 --------------(2)
Add equation (1) & (2) and so, u will be eliminated and we can find the value of t
(1) t + u = 11
(2) <u>t - u = -1</u>
2t = 10
t = 10/2
t = 5
Plugin t = 5 in equation (1)
5 + u = 11
u = 11 - 5
u = 6
The original number is 56
Answer:
The answer is 0.875.
Step-by-step explanation:
7 / 8 = 0.875.
0.875 x 8 = 7. (To check answer)
-4-(-3) = -4+3= -1
The change was -1C
Answer: 20.2
Add all the angles and set it equal to 180
Combine like terms
20x-2=180
X= 9.1
The equation for v is 2x+2
Replace x with 9.1 and then solve
F(x)=18.1+2.2ln(x+1), when x=14
f(14)=18.1+2.2ln(14+1)
f(14)=18.1+2.2ln(15)
f(14)≈24.06 ft (to nearest hundredth of a foot)
