The algebraic expression for the statement : product of x and a subtracted from the product of b and y.
ax - by
x + a - by
by - ax
xa - b - y
If 6 (2 a - 1 ) + 8 = 14, the value of ' a ' is
-1
3 1/12
1 3/12
+ 1
A number is multiplied by 6 and 12 is added to the product.The result is 84 then the number is
- 12
72
+ 12
- 72
If six times a number is 48 then the number is
-8
1
48
8
' 6 less than ten times a ' is written as
6 - 10 a
10 a - 6
10 ac
6 < 10 × a - b
Ages of two friends are in the ratio 2 : 1.If the sum of their ages is 51 then their ages are.
34 years , 20 years
34 years,17 years
20 years, 10 years
30 years, 15 years
If a = b then a x =
b + x
b x
b - x
b ÷ x
6 x - 1 = 2 x + 9 .Then value of x is
1 1/2
-2 1/2
4/10
2 1/2
Half of a number is added to 18 then the sum is 46, the number is
92
56
65
0
