Answer:
2y-x= -10
3y-x = 18
Step-by-step explanation:
The correct option is . 2y-x = -10 , 3y-x = 18
one half x − 5 = 1/2 (x-5)
one third x + 6 = 1/3 *(x+6)
1/2 x-5 = 1/3x+6 =y
y= 1/2x-5
y = 1/3x+6
Now,
y=x/2 -5 equation 1
y = x/3 +6 equation 2
By taking L.C.M of the first equation we get:
y=x/2 -5
y= x-10/2
Now multiply both terms by 2.
2y=x-10
2y-x= -10
Now lets solve second equation:
Take L.C.M of the second equation:
y = x/3 +6
y=x+18/3
Multiply both sides by 3
3y= x+18
3y-x = 18
Therefore the system of equations we get is:
2y-x= -10
3y-x = 18 ....
Answer:
It should be congruent by the AAS congruence theorem
Step-by-step explanation:
The error is in the congruence theorem.
We know that the 2 angles are congruent and one of the sides are congruent. This means that it can either be congruent by ASA or AAS.
It is actually congruent by AAS because it include two angles and the side is opposite of one of the angles.
Answer:12/3=4
ratio 4:1
Step-by-step explanation:
Answer:
The answer is 3.
Step-by-step explanation:
I know this because when the sold 12 cartons, they sold 2 peach. The next day, they sold 18. If they sold 12 the first day and sold 2, we can say 18 - 12 and get 6. 6 is half of 12 or 1. 1 +2 =3.
Have a great day (:
I am sure you will get this right.
Can I have a thanks and brainliest?
Thanks.
Answer: 1 : 3
Step-by-Step Explanation:
No. Of Lines of Symmetry for an Equilateral Triangle is 3.
No. Of Lines of Symmetry for an Isosceles Triangle is 1.
Therefore,
= 1/3
=> 1 : 3
The Ratio of the Number of Lines of Symmetry for an Isosceles Triangle to that of an Equilateral Triangle is 1 : 3
