Answer: -1
Step-by-step explanation:
3x + 1 < 7...subtract 1 from both sides
3x < 7 - 1
3x < 6 ...divide both sides by 3
x < 6/3
x < 2
there will be an open circle on 2....because the problem has no equal sign...the line will be shaded to the left...because it is less then.
The answers are - 3 and 5.
Answer:
x ≈ 3.5 cm
Step-by-step explanation:
Using the sine ratio in the right triangle
sin23° =
=
=
( multiply both sides by 9 )
9 × sin23° = x , then
x ≈ 3.5 cm ( to 1 dec. place )
