Answer:
The length of SO is 46 units
Step-by-step explanation:
<em>In a parallelogram, </em><em>diagonals bisect each other,</em><em> which means meet each other in their mid-point</em>
∵ SNOW is a parallelogram
∵ SO and NW are diagonals
∵ SO ∩ NW at point D
→ That means D is the mid-point of SO and NW
∴ D is the mid-point of SO and NW
∵ D is the mid-point of SO
→ That means D divide SO into two equal parts SD and DO
∴ SD = DO
∵ SD = 9x + 5
∵ DO = 13x - 3
→ Equate them
∴ 13x - 3 = 9x + 5
→ Subtract 9x from both sides
∵ 13x - 9x - 3 = 9x - 9x + 5
∴ 4x - 3 = 5
→ Add 3 to both sides
∵ 4x - 3 + 3 = 5 + 3
∴ 4x = 8
→ Divide both sides by 4
∴ x = 2
→ To find the length of SO substitute the value os x in SD and DO
∵ SO = SD + DO
∵ SD = 9(2) + 5 = 18 + 5 = 23
∵ DO = 13(2) - 3 = 26 - 3 = 23
∴ SO = 23 + 23 = 46
∴ The length of SO is 46 units
You can also do 12+(-3) for the same answer
Answer:
Step-by-step explanation:
50 of 100
= 50%
120 of 1
= 1.2%
7-1/3
= 21/3 - 1/3
= 20/3
Or:
7-1/3
= 21/3 - 1/3
= 20/3
= 18/3 + 2/3
= 6 + 2/3
= 6.6666666666......
Answer:
(a)
(b)
the price of 50 cloud markers is $37.2
Step-by-step explanation:
(a)
Let's assume
price is P
number of markers is N
We are given
The price of a box of 15 cloud markers is $12.70
so,
The price of a box of 42 cloud markers is $31.60
so,
Firstly, we will find slope
now, we can plug values
now, we can use point slope form of line
we can plug value
now, we can solve for P
add both sides by 12.70
(b)
now, we can plug N=50
So,
the price of 50 cloud markers is $37.2
