Eight people go to a movie. Adult tickets cost $15 and children's tickets cost $8

Mathematics
1 answer:
Reptile [31]2 years ago
5 0

Answer: number of adults = 3, number of children = 5

Step-by-step explanation:

let the number of adults be x, and the number of children be y.

x + y = 8 , 15x + 8y = 85

1st equation x 8 = 8x + 8y = 64

8x+8y-15x-8y = 64 - 85\\-7x = -21\\x=3

substitute x=3

3+y=8\\y=5

Given h(x)=-3x-4h(x)=−3x−4, find h(0)
bogdanovich [222]

Answer:

  h(0) = -4

Step-by-step explanation:

Put the value where the variable is and do the arithmetic.

  h(x) = -3x -4

  h(0) = -3·0 -4 = 0 -4

  h(0) = -4

_____

<em>Additional comment</em>

In general, a polynomial function evaluated when the variable is zero will have the value of any added constant. All of the variable terms will be zero. Since the constant in this function is -4, we know immediately that h(0) = -4.

At the beginning of a snowstorm, Nathaniel had 5 inches of snow on his lawn.
vivado [14]

Answer:

In 5 hours he would have 7.5 inches of snow JUST from the snowstorm but the question says that he already had 5 inches in his lawn so that would make 12.5 inches of snow in 5 hours.

The second one says t, it doesn't state a number so lets assume the number is ten. So that's 5 more hours of constant snowfall, this makes our total be the sum of 12.5+7.5. This is equal to 20.

10 hours into the snowstorm Nathaniel had 20 inches of snow in his lawn.

Consider a brainliest if it helps :)

Maya has to type a document of 2160 words. The graph below shows her initial progress. If
aksik [14]

The time it takes to type the document increases proportionately to the

number of words in the document.

  • The time it would take to type the document is; <u>36 minutes</u>

Reasons:

From the possible figure from a similar question, we have;

The points on the graph are; (0, 0), (1, 60), (2, 120), (3, 180), (4, 240)

The graph is a straight line, therefore, given that the starting point is at the origin, using the points, (0, 0), (1, 60), we have;

The slope of the graph = 60

The y-intercept = 0

The equation that represents the proportional relationship shown on the graph is therefore;

y = 60·x

Where;

y = The number of words

x = The time it takes to type the document

The time it would take Maya to type the document of 2,160 words is given as follows;

2,160 = 60·x

Therefore;

\displaystyle Time, \ x = \frac{2,160 \ words}{60 \ words/minute}  = \mathbf{36 \ minutes}

The time it would take Maya to type the document is x = <u>36 minutes</u>
