Step-by-step explanation:
1.n:1
6:8
2.cross multiply
3.8×n÷6×1
8n=6
4 divide both side by 6
=8n÷6=6÷6 :
=8n÷6=1.33...
therefore n=1.33...
Answer:
b. 21
Step-by-step explanation:
The first five mutiples of 7 are:<em> 7, 14, 21, 28, 35. </em>You can get these by multiplying 7 to any integer.
- 7x1 = 7
- 7x2 = 14
- 7x3 = 21
- 7x4 = 28
- 7x5 = 35
In order to get the average of these numbers, you have to add them and divide the sum to the total number of multiples.
Let's add first.
7+14+21+28+35 = 105
Let's divided 105 by 5, which is the number of the multiples of 7.
105÷5 = 21
<em>The answer is 21.</em>
The correct answer is the 3rd option !! good luck
Answer:
yes
Step-by-step explanation:
Given the 2 equations
y = x + 6 → (1)
y = - x + 5 → (2)
Substitute y = x + 6 into (2)
x + 6 = - x + 5 ( add to both sides )
x + 6 = 5 ( subtract 6 from both sides )
x = - 1 ( divide both sides by )
x = = - ← one solution
