Answer:

d. $41.08

Step-by-step explanation:

12.6% = 12.6/100 = 0.126

12.6% of 326 is 0.126(326) = 41.076 ≈ 41.08

A cell phone and phone case cost $110 in total. The cell phone costs $100 more
Olegator [25]

Answer:

Step-by-step explanation:

p + c = 110

p = c + 100

c + 100 + c = 110

2c + 100 = 110

2c = 110 - 100

2c = 10

c = 10/2

c = 5 .......cost of the phone case

p = c + 100

p = 5 + 100

p = 105 <=== cost of the phone

The product of 2 consecutive #s is 4160 what are the numbers?
KengaRu [80]
So the so the product of two consecutive numbers is 4160 or
x(x+1)=4160
distribute
x^2+x=4160
subtract 4160 from both sides
x^2+x-4160=0
find the factor (if you want to know how, just ask in the comments)
(x-64)(x+65)=0
so the answer is x could be 64 or -65
so the number that work are 64,65 and -65,-64
