Answer:
28
Step-by-step explanation:
(35/5) ÷ (-3/4)
= (35/5) x (-4/3)
= 7 x (-4/3)
= -(7 x 4) / 3
= -28 / 3
hence the numerator is 28
Answer: 10 miles
Step-by-step explanation:
Given that :
Company A:
Flat rate = $30
Charge per mile = $1
Company B:
Flat rate = $20
Charge per mile = $2
Let x = number of miles
Company A total :
30 + x
Company B total :
20 + 2x
Miles needed To get the same total :
30 + x = 20 + 2x
30 - 20 = 2x - x
10 = x
Hence, 10 miles will be moved
Answer: 888+88+8+8+8 = 1,000
Step-by-step explanation: First of all line all your eights' up and then split them
You first need to get the equation into y=mx+b form.
y= -3x-1
Now you can use the answer choices and figure out points.
The correct answer when you plug in (2,-7) is C.
-7= -3(2)-1
Answer:
12 hours
Step-by-step explanation:
Let the larger pipe can drain the tank in x hours
Than, time taken by smaller tank to drain the tank= (x+6) hours
If working togather, both pipe can drain the tank= 4 hours
A.T.Q
+ =
=
=
8 x +24= + 6 x
- 2 x- 24= 0
-6 x+ 4 x -24=0
x(x-6) + 4(x-6)= 0
(x-6)(x+4)=0
X= 6, X=-4 is rejected
Hence, time taken by larger tank to fill the drain= 6 hours
Hence, time taken by smaller tank to drain the tank = 6+6= 12 hours
Hence, the correct answer is 12 hours
