Wish I could help wish I knew
2 < 3x - 1 < 5 ....add 1 to all sections
2 + 1 < 3x - 1 + 1 < 5 + 1 ...simplify
3 < 3x < 6...now divide all sections by 3
3/3 < (3/3)x < 6/3...simplify
1 < x < 2 <===
but if u have trouble doing it this way, u can split it
2 < 3x - 1 3x - 1 < 5
2 + 1 < 3x 3x < 5 + 1
3 < 3x 3x < 6
3/3 < x x < 6/3
1 < x x < 2
now put them together.....1 < x < 2 <==
either way, u will get the same answer
Answer:
x =144
Step-by-step explanation:
A straight line is 180 degrees
x+ x/4 = 180
Change 1 to 4/4 to get a common denominator
4/4x +x/4 = 180
Combine like terms
5/4x = 180
Multiply by 4/5 on each side to isolate x
4/5 * 5/4 =180 * 4/5
x =144
Complementary angles equal 90 degrees.
The other angle would be 90 - 70.2 = 19.8 degrees
b#~8=+/"1 sep b=.a#~54=|a-10#.|."1 sep a=.10 to 99
17 71
Alternately:
10#.b#~(8=+/"1 b)*.54=|a-10#.|."1 b=.sep a=. 10 to 99
17 71
The answer is 71.
71 - 17 = 54.
