a student has some $1 and $5 bills in his wallet. He has a total of 17 bills that are worth $53. How many of each type of bill does he have

Answers

Answer:

$1 bills = x and $5 bills = y

x+y = 17 - that expresses the number of bills.

1x + 5y = 53.

Solve the first for x in terms of y and substitute that into the second.

x = 17 - y

17 - y + 5y =53

17 +4y = 53

4y = 36

y = 9

Substitute that back into the first equation: x + 9 = 17 and then x = 8

The knitting club sold 40 scarves and hats at a winter festival and made $700 from the sales. They charged $18 for each scarf and $14 for each hat.



If s represents the number of scarves sold and h represents the number of hats sold, which system of equations represents the constraints of the situation?

Group of answer choices



A. s + h =40

18s +14h = 700

B. 18s +14h =40

s + h =700

C. 40s + h +700

18s + 14h = 700

D. No answer text provided.

Answers

Answer:

               A.       s + h = 40                        18s + 14h = 700

Step-by-step explanation:

club sold 40 scarves and hats so the sum of scarves and hats is 40

s + h = 40       - one of equations

They charged $18 for each scarf and $14 for each hat so:

18×s   - money made from scarves

14×h   - money made from hats

18s + 14h  - sum of money made from scarves and hats so:

18s + 14h = 700      - second of equatinons

                                       

The system of equations represents the constraints of the situation are   s + h = 40 and 18s + 14h = 700.Option A is correct.

What is a linear equation?

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

It is given that, the knitting club sold 40 scarves and hats at a winter festival and made $700 from the sales. They charged $18 for each scarf and $14 for each hat.

If s represents the number of scarves sold and h represents the number of hats sold.

The system of equations is as follows,

s + h =40

18s +14h = 700

Thus,the system of equations represents the constraints of the situation are   s + h = 40 and 18s + 14h = 700.Option A is correct.

Mrs. Phan wants to buy tulips and lilies for her house. She needs at least 5 containers of tulips and at least 5 containers of lilies. Tulips cost $6 per container and lilies cost $4 per container. If Mrs. Phan has a total of $75 to spend for the tulips and lilies, what is the greatest number of containers she can buy?

Answers

Answer:

She can buy a maximum number of 15 containers

Step-by-step explanation:

We are told from the question that:

Mrs. Phan needs at least 5 containers of tulips and at least 5 containers of lilies.

Tulips cost $6 per container and lilies cost $4 per container. If Mrs. Phan has a total of $75 to spend for the tulips and lilies, what is the greatest number of containers she can buy?

Let x represent the number of Can of tulips for both tulips and lilies

x ≥ 5 cans for both tulips and lilies

$6 × x + $4 × x = $75

6x + 4x = 75

10x = 75

x = 75/10

x = 7.5 cans

This means , 7.5 containers for tulips and 7.5 containers for lilies

Adding up both containers, we have :

7.5 + 7.5 = 15 containers

Therefore, the greatest number of containers she can buy is 15 containers

What is Unitary Method?

The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.

The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units. What can be values and units?

For example

Ram spends 36 Rs. for a dozen (12) bananas. 12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.

As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.

This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.

Given:

Price for furniture set = $4,345

a) The sum of these monthly payments

=15×11

=$165

b) Chris pay in the last month of this plan

=4,345-165

= $4180

Why do most student loans involve a co-signer?
a.
Most students won’t be able to afford paying for their loans, and leave that responsibility to their co-signers.
b.
Co-signers were most likely college students themselves and understand what it is like to be a college student.
c.
Most students aren’t responsible enough to know much about any type of loans, so a co-signer is there to make sure everything is secure.
d.
Most students are young enough not to have much of a credit score or credit history, so a second party such as a parent or guardian can establish security of payment.

Answers

The answer is D. Most students are young enough not to have much of a credit score or credit history...

The correct statement is Most students are young enough not to have much of a credit score or credit history, so a second party such as a parent or guardian can establish security of payment.

What is loan?

A loan is the lending of money by one or more individuals, organizations, or other entities to other individuals, organizations, etc.

Students need cosigners in order to qualify for a student loan or student loan refinance. This is because many students don't have an extensive credit history of their own. The other person cosigns the loan application so that the lender will consider their credit and income as well as yours.

Hence, Most students are young enough not to have much of a credit score or credit history, so a second party such as a parent or guardian can establish security of payment.

Step-by-step explanation:

A is true since the sum of the measures of two consecutive angles of a parallelogram is 180 deg.

B is true since opposite angles of a parallelogram are congruent.

C is false since that equation gives x = -1, but x cannot equal -1 since that would make angle 3x - 12 have a negative measure.

D is false for the same reason as choice C.

E is true since x = 20 is the solution of the equations in choices A and B.

The graph below shows how much money you have in savings each week. Use
this graph to answer questions (a – g).
a. According to the graph how much money did you start with in your savings?
b. How much money will you have after 5 weeks of saving?

Answers

Answer:

Step-by-step explanation:

a). Since starting point of the line is (0, 50),

    Therefore, I started with the saving of $50.

b). Since endpoint of the segment is (5, 175),

    Money with me after 5 weeks will be $175.

c). Let the equation of the line given in the graph is,

    y - y' = m(x - x')

    Where (x', y') is a point lying on the graph.

    And 'm' is the slope of the line.

    Slope of the line = [tex]\frac{175-50}{5-0}[/tex]

                             m = [tex]\frac{125}{5}[/tex]

                             m = 25

     Since, the line passes through (0, 50),

     y - 50 = 25(x - 0)

     y = 25x + 50

     y = 25x + 50

     For x = 6,

     y = 25×6 + 50 = 200

     For x = 7,

     y = 25×7 + 50 = 225

     For x = 8,

     y = 25×8 + 50 =250

d). For x = 10 weeks,

    y = 25×10 + 50 = $300

e). For x = 15 weeks

     y = 25×15 + 50 = $425

f). For x = 50 weeks,

     y = 25×50 + 50 = $1300

g). Equation of the line is,

     y = 25x + 50
