Multiply top equation by -2, then add equations so b drops out....solve for a...plug in a to get b
Subtract both fractions. Convert both fractions into improper fractions. So do 3x10+9 and see what ur answer is and put it over ten. Then do 2x16+1 and put the answer u get over 6. Then find the common denominator which is 30. Then subract both fractions and u should get ur answer
Answer:
Step-by-step explanation:
15*20=x
Answer:
x = 3
Step-by-step explanation:
The two triangles at the left have the same angles and share a side, so they are congruent. Therefore, the vertical side is also 6x−2.
Using the same logic, the two triangles on the right have the same angles and share a side, so they are congruent. Therefore, the vertical side is also 9x−11.
So:
6x − 2 = 9x − 11
9 = 3x
x = 3
