Answer is provided in the image attached.
3x+3x-5= 1
6x-5=1
Whenever moving a number, the sign always changes.
6x-5+5= 1+5
6x= 1+5
6x= 6
divide both sides by 6
6x/6= 6/6
x= 1
Check solution by using the substitution method
3(1)+3(1)-5=1
3+3-5=1
6-5= 1
1=1

Answer:
1,260
Step-by-step explanation:
Let's name
LT = number of long term parking spaces
ST = number of short term parking spaces
CP = the number of parking spaces in the cell phone parking
We have
LT/ST = 5/7
ST/CP = 8/9 or CP/ST = 9/8
LT + ST + CP = 3180
Dividing the last equation by ST we get
LT/ST + 1 + CP/ST = 3180/ST
replacing
5/7 + 1 + 9/8 = 3180/ST
Solving for ST we obtain ST = 1,120.
Replacing in the second equation, we get CP/1,120 = 9/8,
hence CP = 1,260
The probability of pulling out a green ball without looking is 3/8 or 0.375 as a decimal of the given problem there are 8 tennis balls in a bag.five of the balls are yellow and the other 3 are green
To find the probability of pulling out a green ball without looking, we need to determine the ratio of green balls to the total number of balls in the bag.
Given that there are 8 tennis balls in total, with 3 of them being green, the probability can be calculated as:
Probability = Number of green balls / Total number of balls
Probability = 3 green balls / 8 total balls
Simplifying this fraction, we have:
Probability = 3/8
Therefore, the probability of pulling out a green ball without looking is 3/8 or 0.375 as a decimal.
