Answer:
Step-by-step explanation:
they are opposite angles, so we put them equal to each other.
25.
6a+10= 130
6a=120 a=20 so now we plug it in 6(20) +10= 130
26. 4a-4=2a+30
2a=34 a=17 sso now we plug in 4(17)-4= 64 2(17)+30= 64
27. 6y+1=4y+9 2x-5=x+7
2y=8 x=2
y=4
now plug in 6(4)+1=25 4(4)+9=25 2(2)-5= -1 (2)+7=9
Answer:
6
Step-by-step explanation:

Hi, can someone please tell me the factors of 2,3,4,5,6,7,8,9,10,11 and 12? Sorry, it is a lot!

Sure.
Factors of 2= 1 & 2
Factors of 3= 1 & 3
Factors of 4= 1, 2, and 4
Factors of 5= 1 & 5
Factors of 6= 1, 2, 3, and 6
Factors of 7= 1 & 7
Factors of 8= 1, 2, 4, 8
Factors of 9= 1, 3, 9
Factors of 10= 1, 2, 5, 10
Factors of 11= 1 & 11
Factors of 12= 1, 2, 3, 4, 6, and 12
Tip: Also, a factor of any number is always 1 and itself, because you can always multiply any number by one to get the same number.
Hope I helped! :D
Answer: x = 3.5
Step-by-Step Solution:
Let us first label the figure.
Let the Triangle be ABC with a line DE || BC.
Now, in ∆ABC,
DE || BC (given)
=> AD/DB = AE/EC (by B.P.T)
Substituting the given values,
AD/DB = AE/EC
2/4 = x/7
1/2 = x/7
2x = 7
x = 7/2
=> x = 3.5
Therefore, x = 3.5
