Tom is 10 years old. his sister lizzy is 4/5 tom's age. tom's mum is 4.25 times as old as lizzy. how old is tom's mum?

Tom's mum is 34 years old.

Step-by-step explanation:

So, Tom is 10 years old, and Lizzy is 4/5 Tom's age. What you want to do is convert that fraction into a decimal which leaves you with 0.80. You then have to multiply 0.80 by 10, which gives you 8. After that, all you have to do is multiply 8 by 4.25, which leaves you with 34. This means Tom's mum is 34 years of age.

the aswere is the one with all 8's and the second one is with the 10,8 and 6

step-by-step explanation:

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
