The answer is: "
40 % " .
_______________________________________________Note:_______________________________________________ If "3/5" of the students ride the bus, then "2/5" do not ride the bus".
Since: "3/5" + "2/5" = "(3 + 2)" / 5 = 5/5 = "1" (as in "1 whole").
1 – (3/5) = (5/5) – (3/5) = (5 – 3) / 5 = 2/5.
________________________________________________Now, express: "2/5" as a percentage ;
→ "2/5" = "x / 100 " ; Solve for "x"
Cross-multiply: Note:
→ Given: "
" = "
" ;
→ " bc = ad" ; {" b
0 ; d
0 "} .
_______________________________________________________As such:
→ "
" = "
" ;
→ " 5x = (2)*(100) " ;
→ Solve for "x" ;
→ " 5x = 200 " ;
→ Divide each side of the equation by "5" ;
to isolate "x" on one side of the equation; & to solve for "x" ;
→ " 5x / 5
= 200 / 5 " ;
to get:
→ "
x = 40 " ;
_________________________________________So; we have:
→ "2/5" = "
40 / 100 " ;
→ "2/5" = "
40 % " .
____________________________________________The answer is: "
40 % " .

Answer:
x = cost of a chair = £22
y = cost of a table = £65
£765
Step-by-step explanation:
Let
x = cost of a chair
y = cost of a table
4x + 2y = 218 (1)
6x + 7y = 587 (2)
Multiply (1) by 6 and (2) by 4
24x + 12y = 1,308 (3)
24x + 28y = 2,348 (4)
Subtract (3) from (4) to eliminate x
28y - 12y = 2,348 - 1,308
16y = 1,040
y = 1,040/16
y = 65
Substitute y = 65 into (1)
4x + 2y = 218 (1)
4x + 2(65) = 218
4x + 130 = 218
4x = 218 - 130
4x = 88
x = 88/4
x = 22
x = cost of a chair = £22
y = cost of a table = £65
Find the total cost of buying twenty chairs and five tables
20x + 5y
Substitute the values of x and y
20x + 5y
= 20(22) + 5(65)
= 440 + 325
= £765
Answer:
X+Y=20
Step-by-step explanation:
(x+2)2+(y-4)2=36
2x+4+2y-8=36
2x+2y=36+4
X+Y=20
Final answer
X+Y=20
