A) double a number, then add 3 b) five times a number, then subtract 7

c) 10 less than twice a number

d)triple a number divided by 2

What algebraic expressions can I write for these words??

a) 2x+3

b) 5x-7

c) 2x-10

d) 3x/2

Step-by-step explanation:

the number considered is x

a and c

for infinitely many solutions we require both left and right sides to be equal

distribute and simplify

a

14 - 8x = 20 - 8x - 6 = 14 - 8x ← both sides equal so infinite solutions

b

6x - 54 = 6x - 54 + x = 7x - 54 ← not equal

c

4x + 16 = 4x + 10 + 6 = 4x + 16 ← both sides equal so infinite solutions

d

5x - 40 + 10 = 5x + 10

5x - 30 = 5x + 10 ← not equal

a) is $10.34

b) is 6 toppings
