Answer:
-6.8w = 3.4
divide both side by -6.8
the left side become w
and the right side become - 0.5
so
w = -0.5
<span>use an expression
s = speed of the slower car
then
(s+20) = speed of the faster car
When they meet is after 400 miles
Write distance equation
slow car d + fast car d = 400 mi
4s + 4(s+20) = 400
8s + 80 = 400
8s = 400 - 80
8s = 320
s = 40 m/H</span>
Answer:
i think x = 4
Step-by-step explanation:
Step-by-step explanation:
3(4 *to the power of 2* - 3*to the power of 2*)
24-23 x 3
3*to the power of 3* - 3*to the power of 2
(6*to the power of 2* - 3) (9*to the power of 2* - 70)
- (6²-3)(9²-70)
- (36-3)(81-70)
- (33)(11)
- 363
Hence, Option d. is the correct answer because it gives answer 3 when it is solved.
