Answers

Answer 1

Answer:

379 : 62

Step-by-step explanation:

Let’s gather the info from the problem.

1580 adults and children on a ship.

60% of them are adults.

percentage of adults and students remaining on the ship decreases by 20%

60% of 1580 is 948 so there are 948 adults onboard

leaving the remaining children which is 632

948 Adults

632 Children

Adults decreases by 20% so 758 adults

Children decreases by 20% so 124 children

the ratio is 758:124 simplified would be 379 : 62

Given that,
An expression is given we have to discuss what the expression 5p + 3 = 15 implies.

What is simplification?

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

here,
Given expression,
5p + 3 = 15
5p = 15 - 3
p = 12 / 5

Given that the points (-32,-10) and (-74,11) lie on a line, what is the equation of the line

Answers

The equation of the line with the points (-21, -10) and (-74, 11) is

y = (-/12)x - 26.

What is an equation of a line?

The equation of a line is given by:

y = mx + c

where m is the slope of the line and c is the y-intercept.

Example:

The slope of the line y = 2x + 3 is 2.

The slope of a line that passes through (1, 2) and (2, 3) is 1.

We have,

(-32,-10) and (-74,11)

The equation of a line is given as,

y = mx + c

m = (11 + 10) / (-74 + 32)

m = 21 / -42

m = -1/2

Now,

(-32, -10) = (x, y)

-10 = (-1/2)(-32) + c

-10 = 16 + c

c = -10 - 16

c = -26

Now,

The equation of the line is y = (-/12)x - 26.

Step-by-step explanation:

When writing the number in standard form you have to look at the decimal point. If you already have a decimal point (like the question) then look for the first non-zero digit (in terms of the question, its 6). You have to move the decimal point to right until its after the first non-zero digit. Count how many spaces you moved, in this case its 7. If you are moving to the left you have to put a negative sign when writing the power of 10.
