Coach went and bought 4 bats and 7 baseballs for $68 the next day bought one bat and one ball for 14 how much is each individual
Crazy boy [7]

Answer:

Baseballs is: $10

Bats is: $4

Step-by-step explanation:

Let x represent bats

and y represent baseballs

So we have :

(1) 4x + 7y = 68

(2) x + y = 14 => y = 14 - x

Use substitution.

Substitute equation (2) into equation (1)

4x + 7(14 - x) = 68

Solve for x

4x + 98 -7x = 68

-3x + 98 = 68

-3x = -30

x = 10

Solve for y, replace x = 2 into equation (2)

y = 14 - 10 = 4, so y = 4

Since x represents bats and y represents baseballs, it cost $10 for the bats and $4 for the baseballs.

Michael's bill at a restaurant was $46.32. He wants to leave a 17% tip. What will the new total be,including the tip?
Novosadov [1.4K]
$7.87+$46.32=$54.19.  If you multiply 46.32 by 0.17, 17%, it is 7.87 so you just add that to the original bill, 46.32

a rectangle has a length of x inches and a width 3 inches less than the length. if the dimensions were doubled , what would be t
iren [92.7K]
Original length: x
original width; x-3
original area: x(x-3)
when the dimensions doubles, that is, increase by a factor of 2, the area increase by 2²
4[x(x-3)]
4x(x-3)=4x²-12x

you can also do it this way:
original length: x        doubled: 2x
original width; x-3      doubled: 2(x-3)
new area: 2x[2(x-3)]= 4x²-12x

In the equation f(x) = (x − h)^2 + k: what does k mean?
Vlada [557]
K would be the the y-coordinate of the vertex. It also determines the translation. If k is greater or less than zero, the function will translate up or down (up if K is positive and down if K is negative).

Answer as fast as u can for 50 pts
Ratling [72]

Answer:

Basketball 300

Football 100

Baseball 50

Soccer 150

Step-by-step explanation:

Half of the students would choose basketball

so 600/2 = 300

Half of the remaining students would choose soccer

so 300/2 = 150

2/3 of the remaining students would choose football

so 150 x 2/3 = 100

1/3 of the remaining students would choose baseball

150 x 1/3 = 50
