Answer:

18/7

Step-by-step explanation:

(7/6)x + 19/2 = 25/2

Subtract 19/2 from both sides

(7/6)x = 6/2 = 3

Now multiply both sides by 6/7 and get

x = 18/7

20 This spinner will be spun twice. What is the probability of
natali 33 [55]

Answer: the probability is 0.25

Step-by-step explanation:

We have 10 numbers:

0, 1, 2, 3, 4, 5, 6, 7, 8, 9

Of those, the odd ones are:

1, 3, 5, 7, 9

So we have 5 odd numbers.

The probability that the outcome is an odd number is equal to the number of odd numbers divided the total number of numbers:

p = 5/10 = 0.5

For the second spin the probability is the same, p = 5/10, because the first outcome does not affect the results of the second spin.

The probability of spining an odd number both times, then is the joint probability for two times this same event:

P = (5/10)(5/10) = 0.5*0.5 = 0.25

or 25% in percent form

Can someone please help me with math.
Inessa05 [86]

4- 20

I created an equation for this one:

4x+x=100

  • 4x= four times the amount of the other number
  • x= the number
  • combine like terms

5x=100

  • divide by 5

x=20

5. One pretzel costs $3

Create an equation:

  • 2s+p=7
  • 4s+3p=17

Mulitply 2s+p=7 by -2 so you can use elimination.

  • -4s-2p=-14
  • 4s+3p=17

Combine equations

p=3
