B. This equation has one solution. v=4
Step-by-step explanation:
Hi, Martin’s answer is incorrect.
A. He has to divide 76 by 19, instead of subtract 19 to 76.
The correct steps are:
19v = 76
Since 19 is multiplying the variable, to eliminate it we have to divide by 19.
v = 76/19
v = 4
B. This equation has one solution. It’s v=4

Answer:
its answer is in high school is ten
Direct proportion equations have the following form:
Where "k" is the Constant of proportionality.
In this case you know that "y" is directly proportional to "x" and when:
Having these values, you can substitute them into the equation and solve for "k":
So, substituting the value of "k" into the first equation shown above, you get that the equation that models the given relationship is:
Now, to find the value of "x", when the value of "y" is -24, you must substitute this value into the equation that models the relationship and then solve for "x". Then, you get:
Therefore, the answers are:
No, he is not. The decimal has to be between 1 and 10, so the decimal would actually be between the 8 and 7 to make 7.83. Then, you multiply that decimal by a power of ten. Since the decimal was moved 5 spaces to the right, the power of 10 will be -5. So it would look like this:
7.83 x 10*-5. (the star means that the following number is a power of ten and meant to be small.)
