x%=x/100
'of' means multiply
30% of 70 means
30/100 times 70=
3/10 times 70=
210/10=
21
answer is 21
Step-by-step explanation:
where are the triangles
Your answer should be positive 3 A.
First equation
a. 3x+5=65
b.3x=60 x=20
29, 30, 31
consecutive integers have a difference of 1 between them
let the 3 integers be n, n + 1, n + 2
then n + n + 2 = 60
2n + 2 = 60 ( subtract 2 from both sides )
2n = 58 ( divide both sides by 2 )
n = 29 ← least integer
thus the 3 integers are 29, 30, 31
