So you have -8w and w to combine. W is 1*w so start with -8+1 or 1-8 if that is easier for you. Than add the -7 to the w we left behind and you have -7w.

Usually you would have two to add, are you sure this is complete? If this is it then all you do is w-8w, which is -7w.

.The conversion of square feet to square yards can be represented by direct variation. Three square yards are equivalent to 27 s
Citrus2011 [14]

Answer:

The constant of variation is 1/9

The equation representing the direct variation is y/x= 1/9

Step-by-step explanation:

In direct variation, y/x=k denotes the equation, with k being the constant of variation. Here, y is the number of square yards and x is the number of square feet. Therefore, as we know that 27 square feet = 3 square yards, we can write one point (x₁, y₁) as (27 square feet, 3 square yards). Plugging x₁ and y₁ into our equation, we get

y/x = k

3 / 27 = k

(3/27) / (3/3) = 1/9* = k

Therefore, the constant of variation is 1/9

Next, as stated previously, y/x = k represents the equation of direct variation. Therefore, y / x = 1/9 as our equation

* because 3 is a factor of both 3 and 27, we can divide both the numerator and denominator by 3 to keep the fraction the same but also simplify it. One way to find the greatest common factor is to list the factors of each number and see the highest number that is a factor of both

if 3 buckets containing 2kg of paint has been used to paint a fence 90 m long and 80 cm high. how many buckets of 2kg of paint a
Anit [1.1K]
3 buckets covers 90m x 80cm = 3 buckets for 90x0.8 = 3 for 72

x buckets covers 200m x 120cm = x buckets for 200x1.2 = x for 240


3/72 = x/240
720 = 72x
x =10 buckets of paint to cover 200mx120cm fence

Rich and Aylen are saving money to buy baseball tickets. Rich has $5 more than 3 times the amount of money Aylen has. Together,
Olenka [21]

Answer:

4x + 5 = 101

Step-by-step explanation:

<u>Step 1: Determine how much money both have</u>

Aylen: x

Rich: 5 + 3x

<u>Step 2: Write an equation and solve</u>

Aylen + Rich = 101

x + 5 + 3x = 101

<u>Step 3: Solve the equation</u>

x + 5 + 3x = 101

4x = 96

x = 24

Step 4: Determine how much money does Aylan and Rich have

Aylan has $24

Rich has 5 + 3(24) = $77

Jon buys a shirt for $40 and then buys socks for $15. He lives in Maine and their
gulaghasi [49]

Jon pays $40 and $15. This means that he pays a total of $55. You multiply the total cost by 0.05, which is $2.75. To convert a number to a percentage, multiply it by 100. So, 0.05 as a percent is equal to 5%.

His sales tax will be $2.75.
