Answer:
1. N4 = a
2. N8.25 = b
Step-by-step explanation:
1000 litre =N3
Each additional 100 litres = 5 k
100 litres
2000 litres
100 litres =5k
2000 litres = x
100x =5×2000
100x =10,000
Divide both sides of the equation by 100
x = 100k
100 Kobo = N1
x =N1
N3+N1 =N4
2. First ten words cost N6
Each additional word cost 45 k
1= 45k
5=x
x = 5×45
= 225 Kobo
100 Kobo = 1 Naira
225 Kobo = x
x = N2.25
N6 + N2.25
x = N8.25 = B

4x + x - 15 + 3 -8x = 13
Combine like terms:
(4x+x-8x) + (-15+3) =13
-3x-12 = 13
+12 +12

-3x = 25

-3 -3
X= -25/3
Answer:
Once.
Step-by-step explanation:
When the equation is graphed the x-axis is intersected/touched only once.
It crosses the x-axis at coordinates (-1 , 0)
When graphed it looks like this:
Answer:
Subtract; x = 12
Step-by-step explanation:
x + 15 = 27
x + 15 -15 = 27 -15 (Subtraction Property of Equality)
x = 12
3.50(68)= small
4.40(15)= medium
6.05(23)= large
3.50(68)+4.50(15)+6.05(23)= total
238+67.5+139.15=total
$444.65=total
11/74 because it results 0,17 while 7/50 results 0,14
