Answer:
first you'd need to divide 7.50 by 6 which will get you (7.50÷6=1.25) then you would need to multiply 1.25 by 50 which will get you $62.50 (1.25×50=62.5).
Use substitution
x + x + 4 = 2
2x = -2, x = -1
Y = -1 + 4, y = 3
Solution: (-1, 3)
Answer:
12-2(n-1).
Step-by-step explanation:
It can be written 12-2n+2=14-2n, so that when n=1, the 1st term is 14-2=12. The 5th term is 14-10=4; the 6th is 14-12=2.
Arithmetic sequences use addition, so each term is a constant amount (common difference) more or less than the last.
Geometric sequences use multiplication, so each term is multiplied by a constant amount (common ratio) to get the next one.

Answer:
For any depth y, y, the width will be given by 2 x, 2 x, so we need to solve the equation above for x x ... 2 − 3 Add 3 to both sides. x + 3 = (y − 2) 2 ... .4 n 100 + n represents the concentration C C of an acid solution after n n mL of 40% solution has been added to 100 mL of a 20% solution. First, find the ..
