I need help with this math lesson ​

Answer:

9,375

Step-by-step explanation:

Each number is multiplied by 5 to get the next number. We can see this by testing multiple number on this set of data.

3*5=15

15*5=75

75*5=375.

Thus, to find the next term in the set of data, we must multiply the last number that we are given by 5.

1875*5=9,375

The next number is 9,375

Hope this helps!

NISA [10]
Get common denominators, and solve for each expression
7/5 - 3/4 = 28/20 - 15/20 = 13/20
1/4 + 2/5 = 5/20 + 8/20 = 13/20

What’s the answer to this
Setler [38]

Answer:

The answere is (9,3)

Step-by-step explanation:

first equation

x - 2y = 3

9 - 2(3) = 3

9-6 = 3

3 = 3

second equations

2x - 3y = 9

2(9) - 3(3) = 9

18 - 9 =9

9 = 9

or

x - 2y = 3

x = 2y + 3

2(2y + 3 ) - 3y = 9

4y +6 - 3y = 9

y + 6 = 9

y =3

x - 2(3) = 3

x - 6 =3

x = 9

so (9,3)

i hope this helpful

A swimming pool is 15 by 30 feet and a consistent 5 feet deep. you are painting the walls and floor of the pool. if a gallon can
lukranit [14]

the bottom of the pool is 15 x 30 = 450 sq feet.

 you the have 2 walls that are 30 x 5 = 150 x 2 = 300 square feet

 then 2 walls that are 15 x 5 = 75 x 2 = 150 square feet

 for a total of 450 +300 +150 = 900 square feet

 1 can covers 250 sq ft

so 900/250 = 3.6

 so you would need 4 cans of paint
