9. A mother is 27 years older than her daughter. A year ago, the mother was twice as old as her daughter. How old is each now? System: Answer

The mother is 55 now and the daughter is 28 now

Step-by-step explanation

Basically the mom is 27 years older than her daughter right? So 27 times 2 because she is double her daughters age. You'll end up with 27x2=54. As the question says, a year ago the mother was twice as old from the daughter. So add 1 year to each of the numbers. 27 becomes 28 and 54 becomes 55. I hope this helps

step-by-step explanation:

convert to decimal

x ≥ 18 is your answer

step-by-step explanation:

let "a number" = x

(2/3)x + 17 ≥ 29

isolate the variable (x). do the opposite of pemdas (parenthesis, exponent (& root), multiplication, division, addition, subtraction).

first, subtract 17 from both sides.

(2/3)x + 17 (-17) ≥ 29 (-17)

(2/3)x ≥ 29 - 17

(2/3)x ≥ 12

next, multiply 3/2 to both sides to isolate the x

(3/2)(2/3)x ≥ 12(3/2)

x ≥ 12(3/2)

simplify. multiply, then divide

x ≥ (12 * 3)/2

x ≥ (36)/2

x ≥ 18

x ≥ 18 is your answer
