Answer:
61
Step-by-step explanation:
let the number be x then twice the number is 2x, hence
42 + 2x = 164 ( subtract 42 from both sides of the equation )
2x = 122 ( divide both sides by 2 )
x = 61
Hence the number is 61
Answer:
4 times
Step-by-step explanation:
35/(3+3+2) = circa 4
61/100 = 0.61
so
the least is 61/100 then 0.65 and then 61.5 last
-7/12=y/-36
times both sides by -36 (-36=12*-3)
-3*-7=y
21=y
y=-21
X(p-6) = z-8 => x = (z-8)/(p-6) if p≠6
