2. 20 less than a number p
3. 4 times the sum of y and 7
4. The children ate t oranges from a box of 20 oranges. How many oranges ae left in the box?
5. Three fourth of the difference of 2x and y
q2)Write as verbal statement
1. 14(2x-3)
2. +54
3. (x+11)-6
4. 3m-1
5. 6 - b
q3 Write as an equation and solve
1. A number decreased by 5 is 23
2. Eight more than the number is 17
3. Five multiplied by the number gives 40
4. If a number is divided by 4, the result is 15

Answer 1

$1. \\ 1) \: \: 60 - 15t \\ 2) \: \: p - 20 \\ 3) \: \: 4(y + 7) \\ 4) \: \: 20 - t \\5) \: \: \frac{3}{4} (2x - y)$

2.

1) 14 is multiplied to the difference of twice of x and 3

2) 54 is added to a number

3) 6 less than the sum of x and 11

4) The difference between thrice of m and 1

5) The difference between 6 and b

$3. \\ 1) \: \: x - 5 = 23 \\ x = 23 + 5 \\ x = \underline{\underline{28}} \\ \\2) \: \: x + 8 = 17 \\ x = 17 - 8 \\ x = \underline{\underline{9}} \\ \\ 3) \: \: 5x = 40 \\ x = \frac{40}{5} \\ x = \underline{\underline{8}} \\ \\ 4) \: \: \frac{x}{4} = 15 \\ x = 15 \times 4 \\ x = \underline{\underline{60}}$
