Let K = km in 7 weeks
Equation:
K = 7(20)
First find one third of the number 72. We can do this by either dividing 72 by 3, or by multiplying 72 by 1/3. I will divide 72 by 3.
72/3 = 24
We have completed half of the problem; one third of the number 72. Now the number Barbie is thinking of is twenty less than the number we just found, 24.
To solve this problem subtract 20 from one third of the number 72; 24.
24 - 20 = 4
The number that Barbie is thinking of is 4.
H=7.
To convert to vertex form, we complete the square. This means we move the constant, c, to the other side.
y=x²-14x+29
y-29 = x²-14x+29-29
y-29=x²-14x
To find the number that we then add to both sides, we look at the value of b (coefficient of x). We take half of that number; -14/2 = -7. Then we square it; (-7)²=49. This means we add 49 to both sides:
y-29+49=x²-14x+49
Now we combine like terms on the left:
y+20=x²-14x+49
Write the right hand side as a square:
y+20 = (x-7)²
Now move the 20 on the left back to the right by subtracting it from both sides:
y+20-20=(x-7)²-20
y=(x-7)²-20
The value of h is 7.
Answer:
Hiii the answer would be a= -4b+8/3
Answer:
39 + 5d
Step-by-step explanation:
First multiply 5 by 9 and 5 by d then subtract 6 from 45 (which you get from multiplying 5 by 9) and you get 39 and multiply 5 by d so you get 39 + 5d
