Answer: x is less than or equal to 50/7
Step-by-step explanation:
7x-18<=32 is solve just like a normal equation. Add 18 on either side so that
7x<=32+18
7x<=50
x<=50/7.
Two-fifths equals 0.4 or 40 percent off, this will help us later. So if the Gameboy was $50.00, then two-fifths off of that or 40 percent would mean that the Gameboy sale price is now $20.00. Quite a steal if you ask me! Multiply the decimal by the original price to find the new sale price for the future. Hope I helped! :)
Given:
quarters and dimes ; 19 pcs
total value of quarters and dimes is 4
q + d = 19
0.25q + 0.10d = 4
q = 19 - d
0.25(19 - d) + 0.10d = 4
4.75 - 0.25d + 0.10d = 4
-0.15d = 4 - 4.75
-0.15d = -0.75
d = -0.75/ -0.15
d = 5
q = 19 - d
q = 19 - 5
q = 14
There are 5 pieces of dimes and 14 pieces of quarters.
2.34 im pretty sure. Hope it helps!
