The total is 256
12 x 5 =60
60x2=120
12x4=48
48x2=96
5x4=20
20x2=40
120+96+40=256
Let the cost of one book= x cents
Let the money john have= y cents
According to the question,
45x=y ...eq(1)
(45+5)(x-5)=y
50(x-5)=y
50x-250=y ...eq(2)
On subtracting (1) from (2).
(50x-250)-45x=y-y
5x-250=0
x=250/5
x=50
Thus, cost of each book is 50 cents and john has 2250 cents.
Hope it helps.
Don't feel shy in saying thx if it helps.
4a + 7b - 12c - (8a - 9b + 12d)
= -4a + 16b -12c - 12d Answer
Answer:
<em>120</em> yards
Step-by-step explanation:
A map scale is a ratio.
1 inch : 30 yards
Multiply both sides of the ratio by 4.
4 * 1 inch : 4 * 30 yards
4 inches : 120 yards
So 6/3 = 2
So there is a scale factor of 2
So 2 x 2 is 4
The answer is 4
