Answer:
x = 125
Step-by-step explanation:
all of the angles in a triangle must add up to 180, so 25 + 30 + x = 180. you can subtract 25 and 30 from both sides and you are left with x = 125.
hope it helps!
Answer:
Step-by-step explanation:
1. - 3x + 32 = - x - 12
-3x + x = - 12 - 32
-2x = - 44
x = 44/2 = 22
2. 8x + 16 = x + 9
8x - x = 9 - 16
7x = - 7
x = - 7/7
= - 1
3. 3x + 2 = 2x - 55
3x - 2x = - 55 - 2
x = - 57

Have an amazing day! :)
Multiply it all together 3/4 is 0.75 2/3 is 0.66 1/2 is 0.5 now do in your calculator 0.75+0.66+0.5 and becase everything is in fractions remember that you have to convert your decimal into a fraction your answer is 1 91/100
So add
1/5+3/8
convert bottom number to same number
5 times 8=40
bottom mub be 40
1/5 times 8/8=8/40
3/8 times 5/5=15/40
add
1/5+3/8=8/40+15/40=(8+15)/40=23/40
so completed 23/40 total
