First answer :D

Have a great day!

Answer:

x = 5

Step-by-step explanation:

Now to solve for our equation:

110 - 4x = 130 - 8x

Subtract 110 from both sides: (110 - 110) - 4x = (130 - 110) - 8x

Simplify: -4x = -8x + 20

Add 8x to both sides: (-4x + 8x) = (-8x + 8x) + 20

Simplify: 4x = 20

Divide both sides by 4: (4x / 4) = (20 / 4)

Simplify: x = 5

Ben's living room is a rectangle measuring 9 yards by 192 inches. By how many feet does the length of the room exceed the width​

Answers

9 yards is also 27 feet and 192 inches is 16 feet. Since you have to find how much longer the length is from the width you would subtract the two. 27-16 is 11

The length of the room is 1.7 times the width of the room.

What is the area of a rectangle?The area of a rectangle is : A = L x BIn mathematics, an expression or mathematical expression is a finite combination of symbols that is well-formed according to rules that depend on the context.Mathematical symbols can designate numbers (constants), variables, operations, functions, brackets, punctuation, and grouping to help determine order of operations and other aspects of logical syntax.

Given is that Ben's living room is a rectangle measuring 9 yards by 192 inches.

length = 9 yards = 9 x 36 = 324 inches

width = 192 inches

Now, we can write -

length/width = L/W = 324/192 = 1.69 = 1.7 {approx.}

Therefore, the length of the room is 1.7 times the width of the room.

Stephanie wants to buy s tomato plants, and Diego wants to buy d tomato plants. Each plant costs $7. Stephanie will use a coupon that gives them $25 off the total cost of all their plants.

If Stephanie buys 6 tomato plants, and Diego buys 4 tomato plants, how much will they pay after using the coupon?

A
$21

B
$45

C
$85

D
$243

Answers

Answer:

Required Expression : 7·(s + d) - 25

Step-by-step explanation :

Cost of each plant both buys = $7

No. of plants Stephanie wants to buy = s

Total cost of plants bought by Stephanie = 7·s

No. of plants Diego wants to buy = d

Total cost of plants bought by Diego = 7·d

Total cost = 7·s + 7·d

                = 7·(s + d)

Discount applied through coupon = $25

So, Total cost of all their plants with discount = 7·(s + d) - 25

B.$45

explanation: each plant costs 7 dollars so...
6x7=42
4x7=28
42+28=70
70-25=45

Adding to his frustration was the fact that very few official papers had made their way to him at Mount Vernon. Washington was a stickler for orderly files that he could search at a moment's notice. This was the most important way he kept himself informed about the hundreds of things happening in the fledgling nation. Unfortunately, when the government clerks had panicked and dashed from Philadelphia, they had abandoned all papers and records in boarded-up houses. No one knew where these documents were; and no one was willing to risk his or her life wandering, through the infected city in search of them.

What conclusion does the cause-and-reflect relationship in this passage support?

Washington lacked the information he needed to govern effectively.
Washington got information in other ways so he could govern effectively.
Washington was so angry at the clerks that he did not govern effectively.
Washington was too frustrated by his missing papers to govern effectively.
