A customer at a store paid $42 for 4 pairs of pants and 3 shirts. At the same store, a second customer paid $2 more for 1 pair of pants and 7 shirts. The price of each pair of pants is the same, and the price of each shirt is the same. Which system of equations can be used to find the price in dollars of each pair of pants, x, and each shirt, y?

Answers

Answer:

The system of Equations:

4x + 3y = 42

x + 7y = 44

Step-by-step explanation:

Let the price in dollars of

each pair of pants = x

each shirt = y

A customer at a store paid $42 for 4 pairs of pants and 3 shirts.

Hence:

4 × x + 3 × y = $42

4x + 3y = 42

At the same store, a second customer paid $2 more for 1 pair of pants and 7 shirts.

This means he, paid $42 +$2 = $44

Hence:

1 × x + 7 × y = 44

x + 7y = 44

The system of equations can be used to find the price in dollars of each pair of pants, x, and each shirt, y is

4x + 3y = 42.... Equation 1

x + 7y = 44..... Equation 2

Kaley's family drove to DisneyLand for spring break. Her mom and dad shared the driving duties for a total of 24 hours. Her mom drove 75 miles per hour, and her dad drove 60 miles per hour. If they drove a total of 1,710 miles, how many hours did each person drive for?

Answers

Answer:

Mom drove for 18 hours.

Dad drove for 6 hours.

Step-by-step explanation:

Given that:

Number of hours for the driving duty = 24 hours

Speed at which the mom drove = 75 miles per hour

Speed at which the dad drove = 60 miles per hour

Total distance driven by both of them = 1710 miles

To find:

Number of hours for which each person drive for ?

Solution:

Let number of hours driven by dad = [tex]x[/tex] hours

Let number of hours driven by mom =  (24 - [tex]x[/tex]) hours

Let us have a look at the formula for Distance in terms of Speed and Time.

[tex]Distance = Speed \times Time[/tex]

Distance traveled by Mom = [tex]75 \times x =75x \ miles[/tex]

Distance traveled by dad = [tex]60(24-x) =144-60x[/tex] miles

As per question statement:

[tex]75x+1440-60x=1710\\\Rightarrow 15x=1710-1440\\\Rightarrow 15x = 270\\\Rightarrow x = 18\ hours[/tex]

So, Mom drove for 18 hours.

Dad drove for 6 hours.

The value of 196 ÷ 3.5 is 56

What is division?

Division is the opposite of multiplication. If 3 groups of 4 make 12 in multiplication, 12 divided into 3 equal groups give 4 in each group in division. The main goal of dividing is to see how many equal groups are formed or how many are in each group when sharing fairly.

For example, if 50 apples are to be shared by 5 people , the number of apples allocated bto a person is 50/5 = 10 apples

196/3.5

to solve the we can multiply the numerator and denominator by 10 to make all whole number

= 1960/35

we can now simplify

divide through by 5

392/7

divide through by 7

= 56

therefore the value of 196/3.5 is 56

It costs Widgeco $2,000 to purchase a machine that produces widgets and $2.75 to produce each widget. If widgets are sold for $4.99 each, which of these represents the profit, P(w), received when Widgeco sells w widgets?

Answers

Answer:

C. P(w) = 2.24w - 2000

Step-by-step explanation:

Starting point is - $2000 as this is spending

Income is calculated as:

-2.75w + 4.99w = 2.24w

So the profit formula is:

P(w) = 2.24w - 2000

Correct option is C from below answer choices

The options are:

A . P(w) = 2.24w + 2,000 B.  P(w) = 7.74w + 2,000 C.  P(w) = 2.24w – 2,000 D.  P(w) = 7.74w – 2,000
