(b-c)/c can be separated into b/c-c/c, which is the same as b/c - 1.
so
a= b/c -1
add one to both sides of equations
a+1 = b/c -1+1
1 cancels out on the right side leaving
a+1 = b/c
multiply both sides by c
c ×(a+1)= (b/c)×c
c cancels out on the right side making
c×(a+1) = b
divide both sides by a+1
c =b/(a+1)
Answer:
$79,508
Step-by-step explanation:
Change 4% to decimal form: drop the percent sign replacing it with a decimal
point then move the decimal point two places to
the left = .04
Salary increase: $76,450 x .04 = $3,058
Total salary: $76,450 + $3,058 = $79,508
Answer: m= -2
7(m+5) = 21
7m + 35 = 21
-35. -35
7m = -14

7. 7
m = -2
Answer: A = 7 unit^2
Explanation:
First let’s cut the shape into 1 square and 1 trapezoid.
After that we can calculate the 2 polygons individually
Find area of square:
A = 2 x 2 = 4
Find area of trapezoid:
A = (2 + 1)2/2 = 3
Find area of the whole shape
