If y varies inversely as X and Y equals 5 when x equals 3 find X when Y is 15​

Mathematics

omeli [17]3 years ago

Answer:

x = 1

Step-by-step explanation:

Given that y varies inversely as x then the equation relating them is

y = \frac{k}{x} ← k is the constant of variation

To find k use the condition y = 5 when x = 3

k = yx = 5 × 3 = 15, thus

y = \frac{15}{x} ← equation of variation

When y = 15 then

15 = \frac{15}{x} ( multiply both sides by x )

15x = 15 ( divide both sides by 15 )

x = 1

We know that 80 T shirts are equal to 100% of the the T shirts

To find 55% of 80, we could cross multiply

80 ?
------ -----
100% 55%

1. We multiple 80 by 55 to get 4,400

PLEASE HELP ASAP……..
bogdanovich [222]

Answer:

4x+2y = 14  The original equation

2y = 14-4x  Subtract 4x from both sides

2y = -4x+14  Rearrange so x is first

y = -2x+7  Divide everything by 2

Explanation:

The steps above practically explain everything needed, so there's not much to add. The standard form is Ax+By = C while slope intercept form is y = mx+b

In the case of y = -2x+7, we have a slope of m = -2 and y intercept of b = 7. This means (0,7) is one point on the line. Use the slope to move down two and to the right one unit to arrive at (1, 5) as another point on this line.

Kay [80]

Answer: 7/12

Step-by-step explanation:

From the question, we are told that Chelsea plays soccer 4/12 of the year and swims 3/12 of the year before taking a break from playing sports.

The fraction of the year that Chelsea spend participating in sports will be the addition of the fraction used for playing soccer and the fraction use for swimming. This will be:

= 4/12 + 3/12

= 7/12
