Answer:
14: 1
Step-by-step explanation:
<em>Cross multiply:</em>
3(2a -3b)= 5(a +b)
<em>Expand:</em>
6a -9b= 5a +5b
<em>Move all a terms to one side, b terms to the other:</em>
6a -5a= 9b +5b
<em>Simplify:</em>
a= 14b
<em>Divide by b on both sides:</em>
<em>Rewriting 14 as a fraction:</em>
∴ a: b= 14: 1
Your answer should be (5, 1). But im not sure what your asking so I may be wrong.
Answer:
B
Step-by-step explanation:
The slope is 4.
Let's find the slope between your two points.
(1,−2); (3,6)
(x1,y1) = (1,−2)
(x2,y2) = (3,6)
Use the slope formula:
m = y2−y1 / x2−x1
= 6− −2 / 3−1
= 8 / 2
= 4
Answer:
m = 4
15 miles cause you do 5 times 3 and you get 15 miles
Answer:
The bike will cover 250 km of distance with 5 liters of petrol.
Step-by-step explanation:
First, we have to calculate the amount of distance the bike will be able to cover in 1 liter of petrol.
Therefore, for every liter, the bike will be able to travel 50 km of distance.
Now, let's multiply the distance travelled by each liter with the total number of liters.
Finally, we have our answer: the bike will cover 250 km of distance with 5 liters of petrol.
Hope this helped!
