Answer:
16 miles
Step-by-step explanation:
<u>Step 1: Make an expression</u>
40% of what distance is 6.4 miles
x * (0.4) = 6.4
0.4x = 6.4
<u>Step 2: Divide both sides by 0.4</u>
0.4x / 0.4 = 6.4 / 0.4
x = 16
Answer: 16 miles
Answer:
add -x to 6x to get 5x then divide by 5 to get 2 x is 2
Step-by-step explanation:hope this helps god bless
Answer:
(x + 1)^2 + (y - 2)^2 = 3^2 = 9
Step-by-step explanation:
The standard equation of a circle with center at (h, k) and radius r is
(x - h)^2 + (y - k)^2 = r^2.
Here, h = -1, k = 2 and r = 3, so the equation of this particular circle is
(x + 1)^2 + (y - 2)^2 = 3^2 = 9.
Answer:
Step-by-step explanation:
common ratio=18/-3=-108/18=-6, a=-3
sn=a(r^n-1)(r-1)
sn=-3((-6)^n-1)(-6-1)
sn=-3(-6)^8-1)/(-7)
s8=-3(1679615)/(-7)
s8=719836
