and work out roots:
$3.75 x 6 =22.50 so Mike has just enough to rent paddleboards for him and his friend for 3 hours with a total remaining of $2.50
Answer:
coefficients: 1, -5
constant: 6
Step-by-step explanation:
The coefficients are the numbers in front of the variables* in each variable term. Here, they are 1 and -5. The coefficient of x² is 1; the coefficient of x in the term -5x is -5.
As you can see, a coefficient of 1 is rarely written.
__
The constant is the value of the term with no variables. Here, the constant is +6.
_____
* Please note that a coefficient can appear anywhere in the product that is a term: -5x = (x)(-5). This means the term x2 that you have written could also be interpreted as meaning 2x. If you mean the 2 in x2 to be an exponent (as we have assumed), then it should be written x^2 or as a superscript: x².
Answer:
0.72
Step-by-step explanation:
1000ml in a litre. 12 x 60 ( minutes in an hour) = 720.
720/1000=0.72
