Answer:
x=2
Step-by-step explanation:
4( 2+x) = 18-x
8 + 4x = 18 - x
4x+x = 18-8
5x= 10
x=2
Answer:
181/20
Step-by-step explanation:
9.05=9 5/100 = 9 1/20
9*20+1=180+1=181
181/20
Answer:
a. 81.9
b. 144.7
c. 110.2
d. 48
Step-by-step explanation:
a. 120/109.2 = 90/x
x = 81.9
b. 45.6/120 = 55/x
x = 144.7
c. 304.8/96 = 350/x
x = 110.2
d. 109.2/45.6 = 115/x
x = 48
Distribute
3x+6>0
Subtract 6 from both sides
3x>-6
Divide both sides by 3
x>-2
Final answer: x>-2
This sequence is doubling the sequence and adding half. When n is your number, you could find the next number in your sequence by plugging in the number:
2n+0.5n
To find the 4th term, we need to plug in 50.
2*50+0.5*50=125
Now, we need to find the 5th term, so we plug in 125.
2*125+0..5*125=312.5
To find the 6th term, we plug in 312.5.
2*312.5+0.5*312.5=781.25
So, the next 3 terms are 125, 312.5, and 781.25
