Answer:
x=3
Step-by-step explanation:
3x + x + x + x − 3 − 2 = 7 + x + x
Combine like terms
6x -5 = 7+2x
Subtract 2x from each side
6x-2x -5 = 7+2x-2x
4x-5 =7
Add 5 to each side
4x-5+5 = 7+5
4x =12
Divide by 4
4x/4 = 12/4
x = 3
Answer:
Step-by-step explanation:
a) 12 - n
1st term = 12 - 1 = 11
2nd term = 12 - 2 = 10
3rd term = 12- 3 = 9
4th term = 12 - 4 = 8
10th term = 12 - 10 = 2
b) 5 - 2n
1st term = 5 - 2*1 = 5 - 2 = 3
2nd term = 5 - 2*2 = 5 - 4 = 1
3rd term = 5 - 2*3 = 5 - 6 = -1
4th term = 5 - 2*4 = 5 - 8 = - 3
10th term = 5 - 2*10 = 5 - 20 = -15
Answer:
x = 80
Step-by-step explanation:
x + 30 = 110 (opposite sides are congruent/equal)
x = 110 - 30 (subtract the 30 from both sides to get X by itself)
x = 80 (simplify)
Answer:
r = 4
Step-by-step explanation:
First we have to subtract 21.50 from 20.50 because that is how much money it takes to get inside the amusement park.
21.50 - 20.50 = 1
Right now you have only 1 dollar left. now we have to divide 100 by 25 to see how many times you can ride.
100/ 25 = 4
You can ride 4 times
