Answer:

  • laura's distance = max's distance + 2 3/4 feet
  • max's distance = 5 feet 5 inches

Step-by-step explanation:

If you consider the English-language meaning of the description of the distances, you can see there might be several ways you could write an equation that says the same thing. Some of them are ...

  laura's distance = max's distance + 2 3/4 feet

  laura's distance - max's distance = 2 3/4 feet

  laura's distance - 2 3/4 feet = max's distance

The first of these equations is shown as an answer above. The last of these equations gives max's distance directly, so is the most useful for finding that value.

  laura's distance - 2 3/4 feet = max's distance

  8 1/6 feet - 2 3/4 feet = max's distance

  5 5/12 feet = max's distance . . . . . . do the arithmetic

_____

Describing addition and subtraction of mixed numbers is beyond the scope of this answer. Many calculators can work with fractions directly, in case you cannot do it by hand.

Nuka is weaving beaded strips. The double number line shows that they can weave 7 \,\text{cm}7cm7, start text, c, m, end text of
Thepotemich [5.8K]

Number lines are used to represent numbers and ratios using regular intervals

Nuka can weave 8.75 cm of strip in 5 minutes

<h3>How to determine the length of strip</h3>

Represent the ratio with:

Ratio = Length : Time

From the number line, they can weave 7cm of the strip in 4 minutes.

So, we have:

Ratio = 7cm : 4 minutes

Represent the length of strip made in 5 minutes with x.

So, we have:

x : 5 minutes = 7cm : 4 minutes

Remove the common units

x : 5 = 7cm : 4

Express as fraction

\frac x5 = \frac{7cm}{4}

Multiply both sides by 5

x= \frac{7cm}{4} * 5

Evaluate the quotient and the product

x= 8.75

Hence, Nuka can weave 8.75 cm of strip in 5 minutes

You have already saved $55. You can earn $9 per hour at your job. You are saving for a bicycle that costs $199. What inequality
Sveta_85 [38]

y = 9x + 55 because the 9x is the amount you get paid an hour, and to get to the 199 you need to include to rate at which you get paid, and add that to how much you already have saved.

Kelsey is putting on sunscreen. She uses 3 ml to cover 45cm to the power of 2 of her skin. She want to know how many milliliters
Artemon [7]

Answer: She would require 16 ml cover 240cm^2 of her skin

Step-by-step explanation:

Let m represent the milliliters of sunscreen required to cover her skin.

Let a represent the area of her skin that was covered. She assumes the the relationship between milliliters of sunscreen and the area is proportional. Introducing the constant of variation, k, the expression becomes

m = ka

She uses 3 ml to cover 45cm^2 of her skin. Therefore,

3 = k × 45

k = 3/45 = 1/15

The expression becomes

m = a/15

The milliliters of sunscreen that Kelsey needs to cover 240cm to the power of 2 of her skin would be

m = 240/15

m = 16 ml
