Actually none of them are the prime factors of 54.
A. indeed are factors, but neither of them are prime.
But you can break down A. into prime factors, 9 = 3*3, 6 = 3*2.
So now you have 3*3 * 3*2, which are all prime.
So the prime factorization of 54 is 3*3*3*2
Question 1:
Let X be the number of miles you can drive.
you need to multiply the price per mile by the number of miles and add that to the rental fee.
The total cost has to be less than or equal to the total amount of money you can spend.
The equation is : 0.35X + 26.20 ≤ 200
Question 2:
The cost of the six drinks and the cost of X hot dogs need to be equal to or less than the 18 dollars they gave you.
The cost for the 6 drinks can be simplified to be 6.00
The equation would be:
6.00 + 1.75x ≤ 18
This can be simplified by subtracting the cost of the drinks from both sides:
1.75x ≤ 12
Answer:
We shall use the method of splitting the middle term
To factorize
3x² - 10 x + 8
We need two numbers which add to give -10 and multiply to give 3 × 8 = 24
The numbers are -6 & -4
(-6)+(-4) = -10
(-6)(-4) = 24
So we shall split -10x as -6x - 4x
We get
3x² -10x + 8
= 3x² -6x -4x+8
Taking out 3x common from first two terms & -4 from the lest two terms we get
= 3x(x-2)-4(x-2)
Taking out (x-2) common we get
= (x-2)(3x-4)
So
3x² - 10x + 8 = (x-2)(3x-4)
Answer:
124/67 and 1/3
Step-by-step explanation:
The second ratio is 1.5/4.5, which readily reduces to 1/3.
Dividing both numerator and denominator of 24.8 / 13.4 by 2 yields the simpler 12.4 / 6.7 or 124/67. This latter result cannot be reduced.
Answer:
3600
Step-by-step explanation: in 1.5 hours there are 90 mins divide 90 by 115 and you get 6 multiply 600 by 6 and the answers 3600
