Answer:
210
Step-by-step explanation:
For getting this answer we need to find the minimum common multiplier, this is, the smaller number that is multiple of all 5, 6 and 7.
For example, 30 is multiple of both 5 and 6, son in 30 days two suppliers will come, but not the third, as 30 is not a multiple of 7.
Let's try with the next multiple of 5 and 6, this is 60, but is not a multiple of 7.
The next is 90, but again not multiple of 7. Niether are the next: 120, 150, 180.
But when we arrive to 210 we see that, as we are going from multiples of 5 and 6, and 210/7=30, 210 is also multiple of 7.
So, the answer is 210.
Answer:
31.5
Step-by-step explanation:
42% of 75 is 31.5. The working is as follows :
<em>42</em><em> </em><em>÷</em><em> </em><em>100</em><em> </em><em>×</em><em> </em><em>75</em><em> </em><em>=</em><em> </em><em>31</em><em>.</em><em>5</em>

Answer:
5/7 and -7/5
Step-by-step explanation:
slope is - 7/5
if line is written as Ax + By + C = 0
the slope is -A/B
if you work that equation you have
By = - Ax - C
y = (-A/B) × x - C/B
and term multiplying the x is the slope in case you had doubts about the - A/B
the multiplication of the slopes of 2 lines that are perpendicular is - 1
x × -7/5 = -1
x = 5/7
the slope of 2 lines that are parallels is the same, so slope = -7/5
