Answer:
the number is three
Step-by-step explanation:
6÷2 is equal to 3, so you do 3x5 which is equal to 15.
Answer:
C and D
Step-by-step explanation:
The quadratic formula is
x= (-b±√b²-4ac)/2a
The formula uses the numerical coefficients in the quadratic equation.
The general quadratic equation is ax²+bx+c where a, b and c are the numerical coefficients
So, lets try and see;
A.

But due to the fact that in this equation you have x⁴, the equation is not a quadratic equation thus can not be solved using this formula
B

C

D.

From the checking above, the equations will be C and D
Answer:
2,784 lbs
Step-by-step explanation:
2900/100=29 (that is 1% of the 2900)
29*4=116 (that is 4% of 2900; how much weight they lost)
2900-116=2784 (current weight)
Answer:
1:3.
Step-by-step explanation:
Probability(getting > 3 on one roll) = 3/6 = 1/2.
So on 2 cubes rolled the probability of getting > 3 is 1/2 * 1/2 = 1/4.
As a ratio this is 1:3.
