Hey there!

“8x + 7 + 7x – 2 = 90”

• FIRST: COMBINE your LIKE TERMS

(8x + 7x) + (7 – 2) = 90

‘8x + 7x = 15x’

‘7 – 2 = 5x’

“15x + 5 = 90”

• SECOND: SUBTRACT by 5 on BOTH SIDES

15x + 5 – 5 = 90 – 5

CANCEL out: 5 – 5 because that gives you 0

KEEP: 90 – 5 because it helps us solve for your x-value

‘90 – 5 = 85’

NEW EQUATION:

“15x = 85”

• THIRD: DIVIDE by 15 on BOTH SIDES

15x/15 = 85/15

CANCEL out: 15/15 because that equals 1

KEEP: 85/15 because it gives us our x-value

Reduce: 85/15 and it gives us: x

Answer: x = 17/3 ☑️

Good luck on your assignment and enjoy your day!

Is 7/9 a rational number ?
zzz [600]

Yes.

Rational numbers can be represented as fractions with integers. The denominator must not equal 0.

If the probability of a win is 0.02, and the probability of a draw is 0.8, what is the probability of a loss?
atroni [7]
A probability is a number between zero and one. 

There are 3 options win, lose or draw. 
This means that (win + loss + draw = 1)

From the information given you know:
Win = 0.02
Draw = 0.8 

So: 0.02 + loss + 0.8 = 1 
Therefor loss = 1 - 0.8 - 0.02 
loss = 0.18 
final answer ^ 

Hope this helps, let me know if you don't get any of it!
