X=y/20-1/4 solve for y and show properties

Mathematics
1 answer:
andriy [413]3 years ago
3 0

Answer:

y = 20x + 5

Step-by-step explanation:

X =  Y/20 - 1/4

In this type of expression you will first of all find the LCM of the right hand side

x = y - 5/ 20

the next thing to do is to cross multiply

we have,

20x = y - 5

dont forget we are to solve for y in the equation, so to solve for y we have

20x + 5 = y

therefore y will be expressed in terms of x as written below

y = 20x + 5

Taryn is shopping for a Christmas tree. At Home Depot the one she likes is $149.00 and she has a 15% off coupon. At Lowe's the o
Vitek1552 [10]

Answer:

Step-by-step explanation:

At home depot

Price of Christmas tree = $149.00

Discount = 15%

Amount discounted = 15% of $149

Amount discounted = 15/100 * $149

Amount discounted = 15 * 1.49

Amount discounted = $22.35

Amount she paid = $149-$22.35

Amount she paid = $126.65

At Lowe's:

Price of Christmas tree = $175.00

Discount = 260%

Amount discounted = 20% of $175

Amount discounted = 20/100 * $175

Amount discounted = 0.2 * 175

Amount discounted = $35

Amount she paid = $175-$35

Amount she paid at Lowe's = $140

<u><em>From the prices above, it can be seen that Home Depot has a better deal since the price after removing discount is lower than that of Lowe's.</em></u>

<u><em></em></u>

<u><em>Amount she will save will be $140 - $126.65 = $13.35</em></u>

Can someone help me please
soldier1979 [14.2K]

Step-by-step explanation:

c >= 2

that means any value of c greater or equal to 2 is a valid solution. so, yes, 2 is a solution for this.

c < 2

that means any value of c smaller than 2 is a valid solution. so, no, 2 is not smaller than 2, so it is not a solution.

c < 3

that means any value of c smaller than 3 is a valid solution. so, yes, 2 is smaller than 3, so 2 is a solution.

3 < c

that means any value of c, for that 3 is smaller, is a valid solution. our in other words, any value for c larger than 3 is a valid solution. so, no, 2 is not larger than 3, so it is not a solution.

-8 < c

that means any value of c, for that -8 is smaller, is a valid solution. our in other words, any value for c larger than -8 is a valid solution. so, yes, 2 is larger than -8, so it is a solution.

HELP ME PLEASE LOVE THOU &lt;3
12345 [234]

Answer:

100\pi

Step-by-step explanation:

Total Surface Area of cylinder = Lateral Surface Area + Area of both circle bases.

Lateral Surface Area = Circumference of Circle \times Height

Lateral Surface Area = (\pi \times2\times5) \times 5=50\pi

Area of one circle base: \pi (5)^{2} =25\pi

Area of both circle bases: 25\pi \times2=50\pi

Total Surface Area = 50\pi +50\pi =100\pi
