Answer:There are 23green marbles
Step-by-step explanation:
If Red marbles x
Green marbles 2x-5+x=37
Total is 3x-5=37
3x=37+5
X=14
Green therefore=2(14)-5=23
The number that should be added to both sides is 16 because its half of b, which is then squared. You then get (x+4)^2=20, which you then square root both sides and get x+4=+-20 and then subtract the 4 to get x=-4+-20
Answer:
x = 9.9 or 10
Step-by-step explanation:
to find missing angle -->
90 + 61 + z = 180
151 + z = 180 *subtract 151 from both sides*
z = 29
to find x -->
tan (29) = x/18 *put tan(29) over 1 then cross multiply*
x = 18 (tan(29))
x = 9.97 --> round up to 10
