John and Ariana bought school supplies, John spent $10.65 on 4 notebooks and 5 pens. Ariana spent $7.50 on 3 notebooks and 3 pen

timurjin [86]

Cost of 1 notebook is $ 1.85 and cost of 1 pen is $ 0.65

<h3><u>Solution:</u></h3>

Let "a" be the cost of 1 notebook

Let "b" be the cost of 1 pen

Given that John spent $10.65 on 4 notebooks and 5 pens

cost of 1 notebook x 4 + cost of 1 pen x 5 = 10.65

4a + 5b = 10.65 ------ eqn 1

Given that Ariana spent $7.50 on 3 notebooks and 3 pens

3a + 3b = 7.50 ----- eqn 2

Let us solve eqn 1 and eqn 2 to get the values of "a" and "b"

Multiply eqn 1 with 3

12a + 15b = 31.95 ---- eqn 3

Multiply eqn 2 with 4

12a + 12b = 30 ------ eqn 4

Subtract eqn 4 from eqn 3

12a + 15b = 31.95

12a + 12b = 30

(-) ---------------------

3b = 1.95

b = 0.65

Substitute b = 0.65 in eqn 1

4a + 5(0.65) = 10.65

4a = 7.4

a = 1.85

Thus cost of 1 notebook is $ 1.85 and cost of 1 pen is $ 0.65

Answer:

The expression that calculates the speed in meters per second of an object that travels a distance of 100 m every 20 s is $\mathbf{Speed=\frac{100}{20} }$

Step-by-step explanation:

We are given:

Distance = 100 m

Time = 20 s

We need to find:

Speed

The formula used is: $Speed=\frac{Distance}{Time}$

Putting values and finding the expression

$Speed=\frac{Distance}{Time}\\Speed=\frac{100}{20}$

So, the expression that calculates the speed in meters per second of an object that travels a distance of 100 m every 20 s is $\mathbf{Speed=\frac{100}{20} }$

<em>Note: Kindly recheck your options, As option B is not written correctly.</em>
