Answer:
7x-5 combine like terms order off operations hope this helped
Step-by-step explanation:
Answer: Angle R is 70 degrees, angle Q is 90 degrees, and the other angle is 19 degrees.
For the missing side I got 9.4
Step-by-step explanation: I got the angles using Tangent and the missing side using the Pythagorean Theorem.
Solve <span>6x+4x-6=24+9x. Combine all the x terms on one side and all the constants on the other:
10x-9x = 24+6, or x = 30. ONE soution.
Solve </span><span>4x+8=2x+7 +2x-20. Combine all the x terms on one side and all the constants on the other: 4x - 2x - 2x = 7 - 20 - 8 => 0 = -21
This is NEVER true, so </span><span>4x+8=2x+7 +2x-20 has NO SOLUTION.
Please try solving equation B yourself. Then I'd gladly comment on your work.</span>
Answer: 3 hope this helped (:
1/5 + 1/4.....lowest common denominator is 20
4/20 + 5/20 = 9/20 <==
