Answer:
46 cm
Step-by-step explanation:
Let p represent the length in cm of 1 bap'ai; let k represent the length in cm of 1 bok'ai. Then we have ...
12p +2k = 100
10p +10k = 100
Subtracting the second equation from 5 times the first, we get ...
5(12p +2k) -(10p +10k) = 5(100) -(100)
50p = 400
p = 8 . . . . cm
Then the second equation tells us ...
10(8) +10k = 100
10k = 20
k = 2 . . . . cm
Then 5p+3k = 5(8) +3(2) = 46 cm.
The distance 5 bap'ai and 3 bok'ai is 46 cm.
The equation is Pk+1.
Pk=2k2.
What you would do is plug in pk+1 into 2k^2
.2(k+1)^2=
2* (k+1)(k+1)
2*(k^2+2k+1)= 2k^2+4k+2
Answer:
The answer is 105.5 kcal/slice of bread.
Step-by-step explanation:
The kcal per gram of:
- protein = 4kcal/g.
- carbohydrate = 4kcal/g.
- fat = 9kcal/g.
Now, you have:
- 1.5 g of fat + 19g of carbohydrate + 4g of protein = 1 slice of bread.
If we multiply the amount of components by his kcal:
- 1.5g * 9kcal/g + 19g * 4kcal/g + 4g * 4kcal/g;
Now gram/gram = 1, and we can cancel the grams in the equation:
- 1.5* 9kcal + 19 * 4kcal + 4 * 4kcal = 105.5kcal;
Finally, the result of the kcal of the slice bread is:
- 105.5 kcal/slice of bread.
7(x + 9 ) - x
Explanation:
the quantity x plus 9 is written x + 9 , plus meaning add.
times the quantity means multiply the quantity x + 9 multiplied by 7
this is written 7(x + 9 )
finally minus x means subtract x
putting it all 'together' we get 7(x + 9 ) - x
Answer: C
Step-by-step explanation:
In this problem, you will need to know the different properties of the equation. Which part tells you if this graph is negative or positive? and more.
First, we notice an x as the exponent. This tells us that this is an exponential equation. Therefore, we can eliminate B and D.
Next, how do we know if the equation is growth or decay?
The 3 and 1.5 are both positive. This tells us that this is equation is exponential growth.
You can always graph the equation to make sure you are correct.
