Answer:
u = (18, 36, 2)
Step-by-step explanation:
Given:
- v=(4,-3,5)
- w=(2,6,-1)
- z=(3,0,4)
and u = 6w+2z
Putting the values of v,w and z in u, we have:
u = 6(2,6,-1)+ 2(3,0,4)
<=> u = (12, 36, -6) + (6, 0, 8)
<=> u = (12+6, 36+0, -6+8)
<=> u = (18, 36, 2)
Answer:
27
Step-by-step explanation:
First solve 3a - 9= 6
3a - 9 = 6 add 9
3a = 15 divide by 3
a = 5
Now that you know a is 5, put that in the other expression.
5a + 2
= 5(5) + 2
= 25 + 2
= 27
Answer:
j= 12
Step-by-step explanation:
j = 36/3
j = 12
First substitute
(3)(4)/4
then simplify.
12/4
then solve
3
Answer:
25%
Step-by-step explanation:
Given that,
The cost price of a cow, CP = $200
Gain = $50
We need to find the gain percentage of the cost price.
SP = CP + gain
= 50 + 200
= $250
![\text{Gain}\%=\dfrac{\text{Gain}}{CP}\times 100\\\\=\dfrac{50}{200}\times 100\\\\=25\%](https://tex.z-dn.net/?f=%5Ctext%7BGain%7D%5C%25%3D%5Cdfrac%7B%5Ctext%7BGain%7D%7D%7BCP%7D%5Ctimes%20100%5C%5C%5C%5C%3D%5Cdfrac%7B50%7D%7B200%7D%5Ctimes%20100%5C%5C%5C%5C%3D25%5C%25)
So, the gain percent is 25%.
