The grade received on a certain teacher's 100-point test varies in direct proportion to the amount of time a student spends prep
dolphi86 [110]

Answer:

She would receive 96 points

Step-by-step explanation:

The grade (Y) received on a certain teacher's 100-point test varies in direct proportion to the amount of time(t) a student spends preparing for the test.

Mathematically

Y= kt

Where k is constant of proportionality

If y= 72 and t= 3

72=k3

72/3= k

24= k

So

Y= 24t

If t= 4

Y= kt

Y= 24(4)

Y= 96

Y = 96 points

She would receive 96 points

cricket20 [7]

Answer:

(B)(0,5)

Step-by-step explanation:

Given the start point at (4,1)

Given the (x,y) coordinates

  • Moving to the left 4 places is: x-4
  • Moving up 4 places: y+4

Therefore, applying the rule(x-4, y+4) to (4,1), we have:

(4-4, 1+4)=(0.5)

The coordinates of the new ordered pair is (0,5).

The correct option is B.

- 5y – 10x=45<br>- 3y + 10x = -5​
Vsevolod [243]

Answer: y = -5; x = -2

Step-by-step explanation:

- 5y – 10x=45

- 3y + 10x = -5​

Combining both equations

-8y = 40

y= 40/ -8

y = -5

Substitute y = -5 into any of the equations to get the value of x

-5 (-5) - 10x = 45

25 -10× = 45

-10x =45 -25

-10× = 20

Divide both sides by -10

x = -2

1/8 of passengers of a train were children. if there were 40 children travelling in the train on a certain day, how many adults
lilavasa [31]

280 adults were there in the train.

What is linear equation definition and example?

  • The definition of a linear equation is an algebraic equation in which each term has an exponent of one and the graphing of the equation results in a straight line.
  • An example of linear equation is y=mx + b. noun. 20.
  • A polynomial equation of the first degree (such as x = 2y - 7)

Given,

      Total children are in the train = 40

     1/8  are children in train and no of children in train ,

      ∴ 1/8 × x = 40

     x = 40 × 8 ⇒ 320

The no of  passenger in train  = 320

in total passenger, 40 are children .

So, rest adults passengers are = 320 - 40 ⇒ 280

There fore, 280 adults were there in the train.
