GIVING BRAINLIEST Write a proportion that could be used to solve for each variable. Then solve. 7 pencils for $1.68 p pencils fo

Evgesh-ka [11]

The proportion that could be used to solve for the variable is:

$\frac{7}{1.68}=\frac{p}{2.88}$ ; p = 12 ⇒ b

Step-by-step explanation:

Direct proportion means that two (or more) quantities increase or decrease in the same ratio

y = k x is the equation of direct proportion, where k is the constant of proportionality
$\frac{y_{1}}{x_{1}}=\frac{y_{2}}{x_{2}}=k$ is the another way to write a proportion

The number of pencils and the cost of them is increased together or decreased together

∴ The number of the pencils and their costs are in direct proportion

- By using the 2nd rule above

∵ The cost of the 7 pencils is $1.68

∵ The cost of p pencils is $2.88

∴ $\frac{7}{1.68}=\frac{p}{2.88}$

The proportion that could be used to solve for the variable is: $\frac{7}{1.68}=\frac{p}{2.88}$

∵ $\frac{7}{1.68}=\frac{p}{2.88}$

- By using cross multiplication

∴ p × 1.68 = 7 × 2.88

∴ 1.68 p = 20.16

- Divide both sides by 1.68

∴ p = 12

The value of variable p is 12

A boat crew rowed 10.5 miles downstream, with the current, in 1.5 hours. the return trip upstream , against the current , covere

alukav5142 [94]

Answer:

The speed of the boat is 5 miles per hours

The speed of the current is 2 miles per hours .

Step-by-step explanation:

Given as :

The distance cover by boat downstream = D = 10.5 miles

The time taken by boat to cover D distance = T = 1.5 hours

The distance cover by boat Upstream = d = 10.5 miles

The time taken by boat to cover d distance = t = 3.5 hours

Let The speed of boat = x mph

Let The speed of current = mph

Now, According to question

∵ Speed = $\dfrac{Distance}{Time}$

<u>For Downstream</u>

x + y = $\dfrac{D}{T}$

Or, x + y = $\dfrac{10.5}{1.5}$

Or, x + y = 7 .......A

<u>For Upstream</u>

x - y = $\dfrac{d}{t}$

Or, x - y = $\dfrac{10.5}{3.5}$

Or, x - y = 3 .......B

Now, Solving eq A and eq B

So, (x + y) + (x - y) = 7 + 3

Or, (x + x) + (y - y) = 10

Or, 2 x + 0 = 10

∴ x = $\dfrac{10}{2}$

i.e x = 5 mph

So, The speed of the boat = x = 5 miles per hours

Put the value of x into eq A

∵ x + y = 7

Or, 5 + y = 7

∴ y = 7 - 5

i.e y = 2 mph

So, The speed of the current = y = 2 miles per hours

Hence, The speed of the boat is 5 miles per hours and The speed of the current is 2 miles per hours . Answer
