Answer:

Number of hats = 8

Step-by-step explanation:

Number of coats = 14 coats

Number of hats = x

Since number of coats is 6 more than number of hats

i.e number of hats + 6 = number of coats

= x + 6 = 14

x = 14 - 6

x = 8

Number of hats = 8

Jerome bought 15 videos from a department store. Some videos were new releases, x, which cost $19, and some videos were classics

Neporo4naja [7]

Answer:

The system of equations is

$x+y=15$

$19x+8y=164$

Step-by-step explanation:

Let

x------> the number of videos of new releases

y-----> the number of classics videos

we know that

$x+y=15$ ------> equation A

$19x+8y=164$ ------> equation B

Using a graphing tool

Solve the system of equations

Remember that the solution of the system of equations is the intersection point both graphs

The intersection point is $(4,11)$

see the attached figure

therefore

the number of videos of new releases is $4$

the number of classics videos is $11$

Answer for B and C please!

Oksana_A [137]

Answer:

2440 km; 1.330 × 10²⁷ kg

Step-by-step explanation:

(a) <em>Radius of Mercury </em>

D = 4.88 × 10^³ km

D = 2r Divide each side by 2

r = D/2

r = (4.88 × 10³)/2

r = 2.44 × 10³ km Convert to decimal notation

r = 2440 km

(c) <em>Mass difference </em>

Difference = 1.898 × 10²⁷ - 5.68 × 10²⁶ Rationalize exponents

Difference = 1.898 × 10²⁷ - 0.568 × 10²⁷

Difference = 1.330 × 10²⁷ kg
