Given the two triangles shown, find the value of x.

Mr. Brenton loves to take his daughter to the park to go sliding. She has to much fun. He has seven- eighths of a tank of gas. H

julia-pushkina [17]

The answer is five times
7 eighths divided by 1 sixth =42 over 8
42 divided by 8 = 5.25
but the answer has to be a whole number so the answer is 5

hope this helps :-D

A rectangle has a perimeter of 80. if the length is four more than twice the width, what is the length of the rectangle

zubka84 [21]

Answer:

28

Step-by-step explanation:

l = length

w = width

p = perimeter

w = w

l + l + w + w = p (adding all the rectangle's sides together gets us our perimeter)

l = 2w + 4 (four more than twice the width)

Substitute 2w + 4 for 'l' in the original equation

(2w + 4) + (2w + 4) + w + w = 80

Solve equation normally:

6w + 8 = 80

6w = 72

w = 72/6 = 12

(w = 12)

Length = 2w + 4

Substitute 12 for 'w':

2(12) + 4 = l

24 + 4 = l

28 = l

The length is 28

Answer:

$\frac{1}{3}$ = $\frac{2}{6}$

To find equivalent fractions, multiply be any number that is the same for the numerator/denominator

You can also divide, but it must be divisible by both the numerator/denominator

There are 12 baseball trading cards in 4 packages. each package has the same number of cards. Write a rule in words for the numb

Tamiku [17]

Answer:

Rule in words:

The number of packages Justin needs to buy to get x cards is x divided by 3.

Rule as an algebraic expresssion:

$y=x/3$

Explanation:

This is a direct variation problem.

Since each package has the same number of cards, the number of cards is proportional to the number of packages.

12 baseball cards in 4 packages means that there are 12/4 = 3 cards per package, so:

The number of cards is 3 times the number of packages.

The number of packages is the number of cards divided by the number of 3.

So, the rule in words for the number of packages Justin needs to buy x cards is one third of x. This table may help you to visualize it:

Number of packages: 1 2 3 4 5

Number of cards: 3 6 9 12 15

To find the algebraic expression that describes the same rule, you can set the following proportion:

$\frac{12}{4} =\frac{x}{y}$

Where y is the number of packages and x is the number of cards.

And from that you solve for y:

$\frac{12}{4} =\frac{x}{y}\\ \\ 12y=4x\\ \\ y=4x/12\\ \\ y=x/3$

Calculate the area of this section of floor in square feet.

ch4aika [34]

Answer:

A total= 0.6703125 ft²

Step-by-step explanation:

A1= 3.9× 14.3= 55.77 in²

A2=1/2 × 14.3× ( 9.6-3.9)= 40.755 in²

A total= A1+ A2= 55.77+40.755=96.525 in²

1 ft= 12 in , 1ft²= 144 in²

Atotal= 96.525÷144= 0.6703125 ft²
