Answer:
x=4
y=1
Step-by-step explanation:
4x=7y+9
4x+y=17
7y+9+y=17
8y=17-9
8y=8
y=1
so
4x=7*1+9
4x=16
x=16/4
x=4
Use proportion:-
4/8 = x / 40 where x is the page that Lauren is on.
8x = 4*40 = 160
x = 160/8 = 20
Page 20.
The highest common factor is found by multiplying all the factors which appear in both lists
a.(13-4b)(a+6)
13a-24b
13 and 24
so we have to factor this
13 =13×1
24=12×2=12 is 6×2=6 is 3×2=3 is 3×1=3×1
Therefore 1 and 1 get canceled
13×3=39
(a )39
like this we have to solve........
