Answer:
550
Step-by-step explanation:
Rewrite in exponential form:
10^3=2x-100
Solve for x:
1000= 2x-100
2x=1100
x=550
1 divided by 50 is 0.02, so it's 0.02
Answer:
C
Step-by-step explanation:
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre and r is the radius
(x - 4)² + (y - 3)² = 16 ← is in standard form → C
Answer:

Look at that website. The part says that (ab*ad)=(ac*ae)
Doing that, we get
9*(9+11x)=10(10+8x)
81+99x=100+80x
19x=19
X=1
