X=percentage in decimal
30x=6
30/30x=6/30
x=1/5=.20
.20=20/100=20%
20%
Answer
the correct answer should be 109
Step-by-step explanation:
2a + 3b = 6
5a + 2b = 4
We multiply the first equation by 5 and the second by 2 and and subtract the second from the first:
10a + 15b = 30
-10a -4b = -8
11b = 22
b = 2
2a + 3(2) = 6
2a = 0
a = 0
Checking,
5(0) + 2(2) = 4
4 = 4, true
Answer:
Step-by-step explanation:
If you factor the expression 7a+21 you can get:
7 × (a+3)
A 90 degree clockwise rotation will leave the sides with the same length,
will leave the angles the same , it will only change the position of the triangle.
The rotated triangle will be congruent to the original triangle
