Answer:
t<45 mins
Step-by-step explanation:
If to qualify you must finish in less than 45 minutes, this simply means your time has to be less than 45 so it would be t<45 mins. If it had said in 45 mins or less, it would say t is less than or equal to 45 but that's not what we have here.
Answer: <em>x </em>= 13
Step-by-step explanation: the equation to solve this is:
4 × (4 + 8) = 3 × (3 + <em>x</em>)
so we solve the first half of that:
4 × (4 + 8)
4 × 12
48
now we have:
48 = 3 × (3 +<em> x</em>)
so we switch the sides to make it easier and solve
3 × (3 + <em>x</em>) = 48
divide both sides by 3
3 × (3 + <em>x</em>) ÷ 3 = 48 ÷ 3
and get
3 +<em> x</em> = 16
now subtract 3 from both sides
3 + <em>x</em> = 16
-3 -3
and finally we get
<em>x </em>= 13
hope this helped :)
