Let's assume that number as x
The product of 7 and a number =7x
and then increased by 1
so, it will become
=7x+1
now, it is between 15 and 43
so, we can write as
now, we can solve for x
Since, we have to isolate x
step-1:
Subtract all the sides by 1
step-2:
Divide all the sides by 7
so, solution is
.............Answer
Answer:
I think -4
Step-by-step explanation:
we have
------> inequality A
The solution of the inequality A is the shaded area below the solid red line
see the attached figure N
------> inequality B
The solution of the inequality B is the shaded area above the dotted blue line
see the attached figure N
therefore
The solution of the system of inequalities is the shaded area between the solid red line and the dotted blue line
see the attached figure N
therefore
the answer in the attached figure N
