Answer:
X= -1
Step-by-step explanation:
(Distribute)
2x+−5=5x+−2
2x−5=5x−2
Step 2: Subtract 5x from both sides.
2x−5−5x=5x−2−5x
−3x−5=−2
Step 3: Add 5 to both sides.
−3x−5+5=−2+5
−3x=3
Step 4: Divide both sides by -3.
Which = -1
Hope this helps :)
Explanation:
Since we have given that
There are 6 gray keys for every 11 black keys .
So, the ratio will be 6:11
Let the number of gray keys be 6x
Let the number of black keys be 11x
Now, according to question,
so,
Answer:
Step-by-step explanation:
We khow that the genetic mutation affect 2 percent of the population .
Let's try to understand what does this mean :
- in a group of 100 people there is possibility of finding 2 people with this genetic mutation
- in a group of 1000 the possibility raises to 20 people so we can deduce that each time we add a zero we add a zero in 2
so :
- 100⇒2
- 1000⇒20
- 10000⇒200
- 100000⇒2000
and so on
Answer: b
Step-by-step explanation: the parallel proportionality theorem states that “if two or more parallel lines are intersected by two transversals, the parallel lines divide the transversals proportionally.” Therefore, you make a ratio and solve:
(4/2)=(6/x) and if you solve, x=3
now, 6+3=9, so 2x-11=9
if you solve for that, x=10
