Answer:

Angela's age  = 16 years

Harriett's age  = 35 years

Step-by-step explanation:

Let Angela's age be x

Harriett's age = 2x + 3

x + 2x +3 = 51

        3x  = 51 -3

        3x = 48

          x =48/3

          x  = 16

Angela's age  = 16 years

Harriett's age  = 35 years

So we don't know how old Kim is.
Jordan is 7 years older, and 4x of Jordan's age equals to 200.

So Jordan is 50 because 50 x 4 = 200.
Back to Kim, 50 - 7 = 43. Kim is 43. 

Now, you write the equation. I helped you alot.

Pls help with this question
VARVARA [1.3K]

Answer:

it would be A

Step-by-step explanation:

the "<" (less sign) would mean B is less than A which is less than D which is less than C. if it is asking to put in the order which is greater than, there would need to be a ">" (greater sign). since there are no greater than signs, the process is flipped to be D is less than C which is less than A which is less than B meaning B is the greatest increasing likelihood, hope this helps :)
