The angle is 35 degrees
(180 - x) = 2(90 - x) + 35
180 - x = 180 - 2x + 35
180 - x = 215 - 2x
180 + x = 215
x = 35
Check:
180 - 35 = 145 supplement
90 - 35 = 55 complement
55*2 = 110 twice the complement
110 + 35 = 145 :)
Answer:
A bracelet cost $446
Step-by-step explanation:
3 Watch : 3(x + 120)
2 Bracelet : 2x
We have the equation:
3(x + 120) + 2x = 2590
3x + 360 + 2x = 2590
5x + 360 = 2590
5x = 2230
x = 446
Answer:
x=27
Step-by-step explanation:
<span>So we are looking for the next number in the number sequence after the number 152. Since 134-128=6, 140-134=6, 146-140=6, 152-6=146 we can clearly see that the pattern is to add number six to each term of the sequence: 152+6=158 is the correct answer.</span>
5x + 9 = x - 23
move x to the other side
sign changes from +x to -x
5x-x+9= x-x-23 ( combine like terms)
5x-x+9= -23
4x+9= -23
move -9 to the other side
4x+9-9= -23-9
4x= -23-9
4x= -32
divide both sides by 4 to get x by itself
4x/4= -32/4
answer:
x= -8
