The total cost of the bracelet will be $96.
The number of charms will be 2.
Step-by-step explanation:
Given,
Cost per charm at Dayton Fine Jewelry = $17
Cost of bracelet = $62
Let,
x be the number of charms
y be the total cost
y = 17x+62 Eqn 1
Cost per charm at Cain Jewelers = $18
Cost of bracelet = $60
y = 18x+60 Eqn 2
For same cost;
Eqn 1 = Eqn 2
Putting x=2 in Eqn 1
Putting x=2 in Eqn 2
The total cost of the bracelet will be $96.
The number of charms will be 2.

Answer:
The speed of the jet in still air is 415 mph and the speed of the wind is 19 mph
Step-by-step explanation:
we know that
The speed is equal to divide the distance by the time
Let
x -----> the speed of the wind in miles per hour
y ----> the speed of the jet in still air in miles per hour
we know that
<em>With a tailwind</em>
----> equation A
<em>With a headwind</em>
----> equation B
solve the system of equations A and B by elimination
Adds equation A and equation B
<em>Find the value of x</em>
therefore
The speed of the jet in still air is 415 mph and the speed of the wind is 19 mph
Answer: Yes.
Step-by-step explanation: If a number ends in 0, 2, 4, 6, or 8, the number even number.
(3x−2)(2x^2+5)
=(3x+−2)(2x^2+5)
=(3x)(2x^2)+(3x)(5)+(−2)(2x^2)+(−2)(5)
=6x^3+15x−4x^2−10
=6x^3−4x^2+15x−10
