Choose a system and make a case for why you would
or would not choose to solve that system by substitution

Answers

Answer 1

Answer:

The method of solving "by substitution" works by solving one of the equations (you choose which one) for one of the variables (you choose which one), and then plugging this back into the other equation, "substituting" for the chosen variable and solving for the other.

b) Amount
Rs 5760, Interest
Rs 1526​

Answers

Given :

Amount, A = 5760 Rs.

Interest in the amount, I = 1526 Rs.

To Find :

We need to find the % rate of interest.

Solution :

Let, us assume it is simple interest.

So,

[tex]Interest = \dfrac{price \times rate \times time}{100}\\\\1526 = \dfrac{5760 \times r \times m}{100}\\\\r = \dfrac{152600}{5760m}\\\\r = \dfrac{26.5}{m}[/tex]

Hence, this is the required solution.

A store pays $81 for a hockey stick and marks the price up by 5%. What is the amount of the mark-up?

Answers

.05 is equal to 5%
So for every dollar the mark up is .05cents
So if you times $81 by .05 this will give you the mark up because each of the 81$ needs .05 added to it.

So $4.05 Is the mark up

And

The cost would be markup and original added together

Step-by-step explanation:

The expression 12(x⁷)(y³) divided by 6(x³)(y) is equal to 2x⁴y².

What is a polynomial?

An expression that consists of variables, constants, and exponents that are combined using mathematical operations like addition, subtraction, multiplication, and division is referred to as a polynomial.

To simplify the expression, we can divide the coefficients and subtract the exponents of the variables with the same base.

Therefore:

12(x⁷)(y³) divided by 6(x³)(y)

= (12/6)(x⁽⁷⁻³⁾(y⁽³⁻¹⁾)

= 2x⁴y²

Therefore, 12(x⁷)(y³) divided by 6(x³)(y) is equal to 2x⁴y².

Point T is at (-3, 8). What are the coordinates of T' after R(y-axis) o R(x-axis)?

Answers

Given:

Point is T(-3,8).

To find:

The coordinates of T' after [tex]R(y-axis)\circ R(x-axis)[/tex].

Solution:

We know that, [tex]R(y-axis)\circ R(x-axis)[/tex] means the figure reflected across the x-axis then reflected across y-axis.

If a figure reflected across x-axis, then

[tex](x,y)\to (x,-y)[/tex]

[tex]T(-3,8)\to T_1(-3,-8)[/tex]

If a figure reflected across y-axis, then

[tex](x,y)\to (-x,y)[/tex]

[tex]T_1(-3,-8)\to T'(-(-3),-8)[/tex]

[tex]T_1(-3,-8)\to T'(3,-8)[/tex]

Therefore, the required point is T'(3,-8).

Maeve has 40 cups of apple juice. She uses 5/8 of the juice to make punch. She then uses the remaining juice to pour single servings that are 1/5 cup each. How many single servings does Mandy pour?

Answers

Answer:

75 single servings

Step-by-step explanation:

First multiply

40*5/8

You’ll get 25

now 40-25=15

Using 15

15 divided by 1/5

15÷1/5

keep change flip

15*5

75

Answer:

75 servings

Step-by-step explanation:

1. Form an equation

As per the given information;

- starts with 40 cups of juice

- uses 5/8 of the juice

-Splits the remaining serving amongst people, giving each person (1/5) of a cup

Hence the equation is;

(40 - [tex]\frac{5}{8}[/tex](40)) ÷ [tex]\frac{1}{5}[/tex]

2. Solve the equation

(40 - [tex]\frac{5}{8}[/tex](40)) ÷ [tex]\frac{1}{5}[/tex]

Simplify;

(40 - 25) ÷ [tex]\frac{1}{5}[/tex]

Dividing by a fraction is the same as multiplying by the fraction's reciprocal;

(40 - 25) * 5

Follow the order of operations, remember the order of operations are;

1. parenthesis

2. exponents

3. multiplication, division

4. addition, subtraction

Parenthsis first

A customer has a credit card that charges 18% simple interest every year. How much interest will the customer save
by paying off a credit card debt of $5,000 at the end of 1 year instead of at the end of 3 years?

Answers

The customer will save interest by paying off a credit debt is $1,800 at the end of 1 year instead of at the end of 3 years

What is simple interest?

Simple interest is the concept that is used in many companies such as banking, finance, automobile, and so on.

A customer has a credit card that charges 18% simple interest every year.

The customer saves by paying off a credit card debt of $5,000 at the end of 1 year instead of at the end of 3 years.

Interest for three years will be

[tex]\rm A_3 = \dfrac{PRT}{100}\\\\\\A_3= \dfrac{5000*18*3}{100}\\\\\\A_3= 2700[/tex]

Interest for one year will be

[tex]\rm A_1 = \dfrac{PRT}{100}\\\\\\A_1= \dfrac{5000*18*1}{100}\\\\\\A_1= 900[/tex]

The saved amount will be

A = A₃ - A₁

A = 2700 - 900

A = 1800

The customer will save interest by paying off a credit debt is $1,800 at the end of 1 year instead of at the end of 3 years
