How do you do this solve 5/2y=10 for y explain

Answers

Answer 1

Answer: $if\ (5)/(2)y=10\ \ \ \ \ |divide\ both\ sides\ by\ (5)/(2)\ (multiply\ by\ (2)/(5))\n\ny=(\not10^2)/(1)\cdot(2)/(\not5_1)\n\n\boxed{y=4}\n===============================\nif\ (5)/(2y)=10\n\n(5)/(2y)=(10)/(1)\ \ \ \ |cross\ multiply\n\n2y\cdot10=5\cdot1\n\n20y=5\ \ \ \ \ |divide\ both\ sides\ by\ 20\n\ny=(5)/(20)\n\n\boxed{y=(1)/(4)}$

Answer 2

Answer: 5/2Y pretty much = 2 1/2 y = 10So all you do is divide both sides by 2 1/2Which leaves Y = 4Also you can say if you still don't understand it, what times itself 2 times and plus half itself = 10 you can say 4Ex: 4 + 4 + (1/2 of 4=2)10 so it's 4

When a rectangle is dilated, how do the perimeter and area of the rectangle change?

Answers

A transformation of a figure in which all of the dimensions of the figure are multiplied by the same scale factor is called a dilation.

Effect of Dilation on Perimeter

Whenever a figure is dilated by a scale factor, the perimeter of the figure changes according to the same scale factor.

Effect of Dilation on Area

When a figure is dilated by a scale factor of $(a)/(b)$ , the area of the figure is dilated by a scale factor of $(a^(2))/(b^(2))$

Example-

Lets imagine a rectangle with length 10 cm and width 8 cm

So area becomes = 10*8 = 80 square cm

Lets suppose the rectangle is reduced by a scale factor of $(1)/(2)$ to produce a new rectangle.

So we will find the square of scale factor = $((1)/(2))^(2)=(1)/(4)$

Now to find the area of the new rectangle(dilated one) we will multiply the area of the original rectangle by 1/4

= $80*(1)/(4)=20$

Hence, area becomes 20 square cm.

How do you write 13.8 in standard form. Word form and expanded form

Answers

Answer and explanation:

To find : How do you write 13.8 in standard form, word form and expanded form ?

Solution :

According to place value system,

Tens Ones Tenths

1 3 8

The standard form of the number 13.8 is

$13.8=138* 10^(-1)=1.38* 10^(1)$

The expanded form of the number 13.8 is

$13.8=1* 10+3* 1+8* (1)/(10)$

$13.8=10+3+0.8$

The word form of the number 13.8 is

13.8 = Thirteen and eight tenths.

Standard Form : 13.8 times 10^0 or just 13.8 because 10^0 is technically 1

Expanded Form : 10+3+0.8

Word Form : thirteen and eight tenths
