Answer: 26
Step-by-step explanation:
Let the number be n.
Now,
twice a number =>> 2n
added to 3 =>> 2n + 3
is divided by the number plus 7 is five thirds =>> (2n + 3) / (n + 7) = 5 / 3
(2n + 3) = (5 / 3) × (n + 7)
3 × (2n + 3) = 5 × (n + 7)
6n+9 = 5n + 35
6n - 5n = 35 - 9
n = 26
Tom wants to save at least $2000. He already got $375. Let x be the amount he still needs to save.
375 + x >= 2000
Subtract 375 from both sides
375 + x - 375 >= 2000 - 375
x >= 1625
So he still needs to save at least $1625.
Hope this helps! :)
