write a two-step equation that involves multiplication and subtraction, includes a negative coefficient, and has a solution of x
2 answers:
Answer:
<em>Hence, the equation is:</em>
<em>and the solution is:</em>
Step-by-step explanation:
A two step equation is a equation that takes just two steps to solve.
Now we have to formulate a two-step equation that involves multiplication and subtraction, includes a negative coefficient, and has a solution of x=7.
negative coefficient means that the coefficient of the variable term must be negative.
so, we take a equation as:
Clearly the coefficient of variable term is: -3 which is negative.
Now we solve the equation as:
Hence, the equation is:

First, to make things easier, let's turn 5/4 into a decimal given a second is equal to 1000 milliseconds.
5/4 = 1,25
1,25 * 1000 = 1250 milliseconds = 1.25 seconds
So, we've found that 45 yards can be covered in 1.25 seconds. Now we'll use the rule of 3:
45 - 1.25
80 - x
Now we solve:
(80 * 1.25) / 45 = x
100 / 45 = x
2,22... = x
So, according to our answer, 80 yards can be covered in 2,22 seconds, which in fractions would be:
