Beverly has a bag of marbles that weighs 30 grams. She knows that each marble weighs 1.5 grams and the bag weighs 1.5 grams.

Which equation could she use to determine how many marbles are in the bag? Select all that apply.
(1.5)x + 1.5 = 30
30 – x = 2(1.5)
(1.5)(30) = 1.5x
1.5 + x = 30
1.5x = 30 – 1.5

Answer:

This means that your score is lower than her score.

Answer:

x = 12

y = -23

Step-by-step explanation:

to solve for this i think we have to do:

   y = -3x + 13

   -

   y = -2x + 1

-----------------------

   0 = -x + 12

-x = -12

x = 12

then i think.... i think you have to substitute to one of the equations

y = -3(12) + 13

y = -36 + 13

y = -23

then to check we substitute  to the second equation

-23 = -2(12) + 1 ?

-23 = -24 + 1?

-23 = -23

Answer:

7598.8 [tex]cm^{2}[/tex]

Step-by-step explanation:

v (volume) = π[tex]r^{2}[/tex]h

v = 3.14 x [tex]11^{2}[/tex] x 20

v = 3.14 x 121 x 20

v = 7598.8

Answer:

7598.8 cm³

Step-by-step explanation:

Given :-

height = 20 cm

radius = 11 cm

value of π = 3.14

Formula to be used :-

Volume of cylinder = πr²h

Inputting the values :-

V = 3.14 x 11 x 11 x 20

= 3.14 x 121 x 20

= 3.14 x 2420

= 7598.8 cm³

Answer:

x= 0 and y=1

Step-by-step explanation:

1st multiply the first equation by 3

3 (3x-2y=2)

9x-6y=6

multiply the next equation by 2

2 (5x-3y=3)

10x-6y=6

subtract equation 1 from 2

(10x-6y)-(9x-6y)=6-6

10x-9x-6y+6y=0

x=0

put X in equation 1

3 (0)-2y=2

-2y=2

y=-1

so X and y are 0 and -1 respectively

Answer:225:)

Step-by-step explanation:

We see : 4x - 5y = -20

We can write the negative form of 4x - 5y by switching the signs : - (4x - 5y ) = -4x + 5y

Since -4x + 5y is the negative form of 4x - 5y, the result should also be the opposite : 20

And -4x + 5y is indeed 20, so the answer is infinitely many solutions.

Answer:

infinitely many solutions

Step-by-step explanation:

4x - 5y = - 20 → (1)

- 4x + 5y = 20 → (2)

add (1) and (2) term by term

0 + 0 = 0

0 = 0 ← true statement

this indicates the system has infinitely many solutions

Answer:

y = x - 1/5

Step-by-step explanation:

y = x - 1/5

Answer:

The difference between a two step equation and a inequality equation is that two step equation you can isolate the variable and get the answer. However in a inequality equation you can only compare, for example A > 7

Step-by-step explanation:

A inequality compares not giving a clear answer. A two step equation lets you find a clear answer.

A. As the population of the beaver represents a certain law along with the year.

B. The point Q labels that 3.5 years after 1995 the amount of beaver has grown up to 475 approximately.

C. According to the question, the population is grown exponentially.

p(t) pass through point ( 1, 100), (2, 200), ( 3, 400), ( 4, 800)

therefore, 200 = 100 x 2 = 100 x 2 ^1 = 100 x 2^ 2-1

400 = 100 x 4 = 100 x 2 ^2 = 100 x 2^ 3-1

800 = 100 x 8 = 100 x 2 ^3 = 100 x 2^ 4-1

Answer = p (t) 100 . 2 ^ t-1

The average conversion energy from producers to primary consumers will be 10%

As we know that energy can not be created nor be destroyed but it can only be transferred from one form to another.

So the primary consumers take energy as food and this energy is utilized in their metabolism and the remaining they transfer.

The average conversion energy from producers to primary consumers is only 10%.

This percentage actually holds true for all transfer of energy at any trophic level in the food chain.

Majority of the energy loss can be attributed to metabolic processes that give off heat and other forms of energy.

Step-by-step explanation:

m = (y2 - y1)/(x2 - x1)

= 5 -(-1) / -3-6

= 6/-9

= -2/3

(y - y1) = m(x - x1)

y -(-1) = -2/3(x - 6)
