Multply both sides of the equation by 7.

When the variable is in the numerator of a proportion like this, you can solve it by multiplying by that denominator. That multiplication cancels the denominator and gives you the value of the variable.
In general, you multiply by the reciprocal of the coefficient of x. When that coefficient is 1/7, you multiply by 7/1. Of course, you know that 7/7 = 1 and that x/1 = x.
Answer:
5 inches
Step-by-step explanation:
we know that
The scale drawing is
using proportion find out the width of the great room on her plan
S ( s + 1)/ 2
so <span>The sum of the first 100 positive numbers
100(100 + 1) / 2
= 50(101)
= 5050</span>
Because of the -2 at the end of the function, we know it is shifted down. The +1 means it is shifted left. The answer is the last graph (the one with a y-intercept of -1).
