Are there any answer choices?
If the two triangles are congruent, then you can conclude that they have 3 angles in common, or that they are identical or that you could use rigid motions (dilations, translations or reflections) to align them together.
-4a - 6 = -12
-4a = -12 + 6
-4a = -6
a = -6/-4
a = 6/4
a = 3/2
a = 1 1/2
The answer is c
4. You would need to set up equations. Two per problem. So 5x+2s=98. And 9x+2s=154. Then you would multiply one of them by a negative one to make the 2 student tickets cancel out. I would use the top one. So it turns to -5c-2s=-98. The -2c and 2c cancel out. You put the rest together to get 4X=56. And 56/4 is 14. So the senior tickets (X) are 14$. You would then replace X with fourteen one of the original equations. Again I'm going to use the first one. So 5(14)+2c=98. 5x14 is 70. Subtract 70 from both sides to get 2c=28. Divide both sides by 2 to get C=14. So the student tickets are 14$ and the seniors are also 14$.
5. Same thing on this one. Two equations. 8h+7i=84 and 3h+1i=25. Like going to multiply the second equation by -7 so the i's will cancel out to get -21h-7i=-175. So you will end up with -13h=-91. Divide both sides by -13 to get H=7. Replace H in one of the equations. I'll use second one. So 3(7)+1i=25. 3x7=21 so subtract 21 from both sides to get i=4. So the ivy is 4$ and the hostas are 7$.
Hope that helped a little bit!
Step-by-step explanation:
Let EF and GH are the two lines segment of length a and b such that a> b
We can construct line AB by using ruler and compasses.
- Step 1: Draw a line longer than the combined length of EF + GH or (a+b) and mark a point A on it
- Step 2: Using a compass, cut a line segment AC on line l equal to the length of EF by keeping its metal point of A
- Step 3: Using a compass, cut a line segment BC on line l equal to the length of EF by keeping its metal point of B
- Step 4: Using a compass, cut a line segment AH online AC equal to haft of the length of AC
=> we have a line segment with length equal to (EF+GH)/ 2
Hope it will find you well.
