Answer:
Step-by-step explanation:
6x=1/2(2x +7) Multiply both sides by 2
2*6x = 1/2(2x + 7)*2
12x = 2x + 7 Subtract 2x from sides
12x-2x =2x-2x+7
10x = 7 Divide by 10
x = 7/10
x = 0.7
Let's check it
6(0.7) = 4.2
1/2 (2*0.7 + 7)
1/2 (1.4 + 7)
1/2 ( 8.4)
4.2
Both sides check. The answer must be x = 0.7
Answer:
7 units
Step-by-step explanation:
If the line is a straight line, count the number of units in between the two pints of the line.
If you count the units between the two pints on your screen, you will see that the answer is 7 units. This is because there are 7 units in between the two points of the line.
Let the amount of adult tickets sold be x
Since the total of 380 tickets sold consists of the amount of adult tickets and the amount of children tickets that are 70 fewer:
x + (x - 70) = 380
2x - 70 =380
2x = 450
x = 225
Therefore, the amount of adult tickets sold is 225
45 divided by 5 is 9, so it takes 9 minutes to cover 1 mile.
9 x 2 = 18.
