Add 5x+2x+3x you get 10x bring the 20 down set it equal to 180
you have 10x+20=180
subtract 20 from 180 which gives 160
So now you have 10x=160
divide 10 by both sides you get x=16
The answer is A. 11 x 17 - 11x because you would use the <u>distributive property</u> and multiply the number on the outside (11) by everything on the inside (17 and -x)
Answer:
x < 1
Step-by-step explanation:
x is less than 1, we can see
we have an open circle, so <u>x is </u><u>only less</u><u> than 1</u>
it does not include 1
so answer is x < 1
Answer:
Step-by-step explanation:
Answer:
∠RQS = 21°
∠TQU = 28°
Step-by-step explanation:
90° + 221° + 3x + 4x = 360°
combine like terms:
7x + 311° = 360°
subtract 311° from each side of the equation:
7x = 49°
divide both sides by 7:
x = 7°
∠RQS = 3x = 3(7°) = 21°
∠TQU = 4x = 4(7°) = 28°
