Answer:
Step-by-step explanation:
<u>Given system:</u>
Eliminate r to solve for s.
<u>To do so, double the first equation and then subtract the second one:</u>
<u>Subtract</u>
- 4s - (-s) = 104 - 4
- 5s = 100
- s = 100/5
- s = 20
Correct choice is (4) 20
Answer:
yes true I once made a post like this but the mods deleted it before I could put it up lol XD
A is correct. Hope my answer helped u :)
First we can find the line RT which is the square root of 40^2-32^2 which is equal to 24.
RT=24
Right Triangle Altitude Theorem Part: The measure of the altitude drawn from the vertex of the right angle of a right triangle to its hypotenuse is the geometric mean between the measures of the two segments of the hypotenuse.
The geometric mean of 32 and TS is 24, so set up equation.
2nd root or square root of 32*TS=24
32*TS=576
TS=18
QS=18+32=50
I hope this answer helped if you have any questions feel free to ask me in the comments.
Answer:
Rebecca is 12
Jennifer is 16
Step-by-step explanation:
28 - 4 = 24
24 : 2 = 12
12 + 4 = 16 (Jennifer)
28 - 16 = 12 (Rebecca)
