Mr. Robinson gets $5.99 off which is $24.00
Mr. Chang gets $2.50 off which is $22.50
Work:
29.99x.20=5.99 29.99-5.99 = 24.00
25.00x.10=2.50 25.00-2.50 = 22.50
Answer:
2.8, 4.6, 7, 17
Step-by-step explanation:
Answer:
None of the pairs of expressions are equal
Step-by-step explanation:
• 2n ≠ 2 +n
2n is the same as 2 times of n (expressed as a multiplication sign), while 2 +n is the addition of 2 to n.
•n² ≠ 2n
n²= n ×n
2n= 2 ×n
• 2n² ≠ (2n)²
Note that in the latter, there is a bracket which means that the square applies to both 2 and n.
(2n)²
= (2)² × n²
= (2 ×2)(n²)
= 4n²
Thus, none of the pairs of expressions are equal.
Y = mx + b
4 = (2)(-3) + b
4 = -6 + b
10 = b
Answer is choice D
Answer:
1 
Step-by-step explanation:
Note there is a common ratio between consecutive terms, that is
10 ÷ 20 = 5 ÷ 10 = 2 
÷ 5 =
Thus to obtain the next term in the sequence multiply the previous term by
2 × = 1
