3x+8=15 find try the value of x

Answers

Answer 1
Answer:

Answer:

x = 7/3

Step-by-step explanation:

To find the of x, isolate it from the other numbers (moving everything to the other side)

What you do to one side, you must do to the other:

3x + 8 = 15

3x + 8 - 8 = 15 - 8  (subtract 8 on both sides to rid of the "+ 8")

3x = 7

3x/3 = 7/3   (divide by 3 on both sides to rid of the 3 attached to "x")

x = 7/3
Answer 2
Answer:

Answer:

x=2.3

Step-by-step explanation:

15-8=7

Divide 3 on each side (3x=7)7 divided by 3 is 2.3

so X=2.3

22.48 as a whole number

Answers

The answer is 22, this is the answer because when you're rounding to the nearest whole number, you look at the number right next to the whole number. In  this case, the number is 22.48, you can rewrite this as 22 & 48/100. So since the 4 in .48 is lower than 5, you do not bump up the whole number. Making it 22

Let x = Initial Price

If we increase x by 5%, we are adding 0.05x

Therefore, the new price = x + 0.05x = 1.05x

If the ticket has increased by £2.30, £2.30 is 5% of the initial price, or 0.05x

0.05x = 2.30

x = 2.30/0.05

x = 46

Therefore, the price of the ticket before the increase was £46

You can also check this backwards by doing 46*0.05 = 2.30
