Answer:
375
Step-by-step explanation:
Put the equations in for r and c
p(c)=10x-(4x+15)
put the negaive in
10x-4x-15
6x-15
Answer is C
Answer:
ST = 20
Step-by-step explanation:
Line segment RS and segment ST must add up to line segment RT
Step 1: Define
RS = 17
ST = x + 6
RT = 3x - 5
Step 2: Set up equation
mRS + mST = mRT
17 + x + 6 = 3x - 5
Step 3: Solve for <em>x</em>
x + 23 = 3x - 5
23 = 2x - 5
28 = 2x
x = 14
Step 3: Find mST
ST = x + 6
ST = 14 + 6
ST = 20
LCM = 1260
The lowest common factor is 1260
Hope this helps! :)
Answer:
11
Step-by-step explanation:
3+(−3)^2−(9+7)^0
=3+9−(9+7)^0
=12−(9+7)^0
=12−16^0
=12−1
=11
any number to the power of 0 is ALWAYS 1
