a) subtract 4 from the sum of 2x and 5y
b)Add 9z to the product of 3x and 7y
c)multiply the product of 7x and 11y by 2x
d) divide the sum of 3z and 7s by 5a
f) Thrice the value of w divided by the sum of 3x and 7y


pls answer fast I need this by tmr​

Answer 1

a) (2x + 5y) - 4

b) 21xy + 9z

c) 154x²y

d) (3z + 7s) ÷ 5a

f) 3w ÷ (3x + 7y)

Explanation:

Algebraic expressions:

a) Sum of 2x and 5y : 2x + 5y

Subtract 4 from (2x + 5y) : (2x + 5y) - 4

Ans: (2x + 5y) - 4

b) Product of 3x and 7y: 3x * 7y = 3*7 * x*y = 21xy

Add 9z to 21xy: 21xy + 9z

Ans: 21xy + 9z

c) Product of 7x and 11y: 7x * 11y = 7*11*x*y = 77xy

Multiply (77xy) by 2x: 77xy *2x = 154x²y

Ans: 154x²y

d) Sum of 3z and 7s: 3z + 7s

Divide (3z + 7s) by 5a: (3z + 7s)÷ 5a

Ans: (3z + 7s) ÷ 5a

f) Sum of 3x and 7y: 3x + 7y

Thrice the value of w: 3*w = 3w

3w divided by (3x + 7y) : 3w ÷ (3x + 7y)

Ans: 3w ÷ (3x + 7y)
