Answer: 65 kmh
Step-by-step explanation:
70 kmh for 2 hours = 140 km.
63 kmh for 5 hours = 315 km
140 + 315 = 455/7 total hours = 65 kmh
Answer: 13/7 or as a decimal 1.857142857
How did i get the answer:
Step 1: Simplify both sides of the equation.
so 1/2 of 10 is 5, 1/2 of 16 is 8
-3/5 of 15 is -9 and -3/5 of -35 is POSITIVE 21
all together should look like 5x+8+−13=−9x+21
(now we have to combine like terms)
8+ -13= -5
5x -5 = -9x+21
Step 2: Add 9x to both sides
5x + 9x= 14x
14x -5 = 21
Step 3: Add 5 to both sides.
21+5= 26
14x=26
Step 4: Divide both sides by 14.
26/14= 1.85714286 or 13/7
<em>Factors and multiples are related by multiplication.</em>
<h2>
Explanation:</h2>
When you multiply numbers together to find a number, say, n, then those numbers are called factors of n. For instance:

On the other hand, a multiple, say, n, results when multiplying a number by an integer. For instance:

So
is multiple of

<em>As you can see, both factors and multiples implies a multiplication. So factors and multiples are related by multiplication.</em>
