Let Hannah = X and Heather = Y.
The sum of their ages is 30, so you would have x + y = 30
Then Hannah's age is 4 less than 2 times Heather's age so X = 2y-4
The equations are :
X + Y = 30 and X = 2y - 4
The answer is C.
I think its 8×4√16
Explenation:
√128 = 11.3
√16×√8=6.3
8√2= 11.3
so i think you see the patern there and the answer should be 11.3 or 6.3
8√4×√2= 19
19÷2=9.5
9.5÷2=4.75
since 5 is too big to put in the equation and equal 128 then its 4.
To find the second one just do 4², which is 16
So yeah 8×4√16
The answer is 0.35, you could easily search it up on a calc and i just wanted to answer for points
Answer:
it would move 4 in the negative direction
1. 30 in
2. 40 in
I hope this helped
