Step-by-step explanation:
(i)
+ = 1 ( multiply through by 6 to clear the fractions )
2x + 3y = 6 ( subtract 2x from both sides )
3y = - 2x + 6 ( divide through by 3 )
y = - x + 2
(ii)
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope ( gradient ) and c the y- intercept )
y = - x + 2 ← is in slope- intercept form ( that is part (i)
with gradient m = -

TROLLER
X=one dollar
y=5 dollar
x=3y
1x+5y=40
3y+5y=40
8y=40
divide 8
y=5
x=3y
x=3(5)
x=15
15 one dollars
5 five dollars
17/20
multiply top and bottom by 5 ( need to be over 100)
17 x 5 = 85
20 x 5 = 100
85/100 = 0.85
0.85 = 85%
85% is your answer
hope this helps
So you know that the total width of the posters is 4 + 4 + 4 so 12 inches.
you also know that the ratio of the total poster width to the width of the advertisement is 4:5
so to find the width of the whole board you do
12 / 4 = 3
3 x 5 = 15 inches
then you know that
4t = 15-12
4t = 3
t = 3/4 inches
