Mackey invested some money in an account paying 6% interest for one year. She invested $1000 more than this amount in an account paying 8.5%. How much did she invest in total if the total interest earned in the year was $737.50?

Answers

Step-by-step explanation:

Let's assume the amount Mackey initially invested in the 6% account is x dollars.

According to the given information, Mackey invested $1000 more than x in the 8.5% account, which means she invested (x + $1000) dollars in that account.

The total interest earned from the 6% account would be 0.06x dollars, and the total interest earned from the 8.5% account would be 0.085(x + $1000) dollars.

The total interest earned in the year is given as $737.50, so we can set up the equation:

0.06x + 0.085(x + $1000) = $737.50

Simplifying the equation:

0.06x + 0.085x + 0.085($1000) = $737.50

Combining like terms:

0.145x + $85 = $737.50

Subtracting $85 from both sides:

0.145x = $737.50 - $85

0.145x = $652.50

Dividing both sides by 0.145:

x = $652.50 / 0.145

x ≈ $4500

Therefore, Mackey initially invested approximately $4500 in the 6% account, and she invested $1000 more, which means she invested a total of $5500.

$4500

Answer:

1and3

Step-by-step explanation:

Answer: 1st box = 2/3

2nd box = 16/3

==============================================

Work Shown for the 1st box

2/3 = x/1

x = 2/3

There's not much in terms of steps

------------

Another approach for the 1st box

2/x = 3/1

2*1 = x*3

2 = 3x

x = 2/3

------------

Work Shown for the 2nd box

2/3 = x/8

2*8 = 3*x ... cross multiplying

16 = 3x

x = 16/3

Optionally this can be converted into a mixed number

16/3 = (15+1)/3

16/3 = 15/3 + 1/3

16/3 = 5 + 1/3

16/3 = 5 & 1/3

Answer:

Step-by-step explanation:

Divide both sides of the equation by 6.

Add the numbers.

Change the signs.

Answer:

x = -7

General Formulas and Concepts:

Pre-Algebra

Order of Operations: BPEMDAS

Brackets Parenthesis Exponents Multiplication Division Addition Subtraction Left to Right

Equality Properties

Step-by-step explanation:

Step 1: Define

6(-x - 3) = 24

Step 2: Solve for x

Divide 6 on both sides:                    -x - 3 = 4Add 3 on both sides:                        -x = 7Divide -1 on both sides:                    x = -7

Step 3: Check

Plug in x into the original equation to verify it's a solution.

Substitute in x:                    6(-(-7) - 3) = 24Multiply:                               6(7 - 3) = 24Subtract:                              6(4) = 24Multiply:                               24 = 24

Here we see that 24 does indeed equal 24.

∴ x = -7 is the solution to the equation.

Tina chose A as the correct answer. How did she get that answer?

Answers

Answer: Tina is correct

Step-by-step explanation:

this is because in one foot there are 12 inches and there are 5 feet so 5 X 12= 60 and aaron is 63inches so he is tall enough and 63-60=3 inches so he is 3 inches taller than 5 feet.

Pls give me brainliest!!!

Answer:

Yes. He is 3 inches taller than 5 feet

Step-by-step explanation:

We know that 1 ft is 12 inches

5 ft  * 12 inches/ 1 ft = 60 inches

You must be 60 inches to ride and Aaron is 63 inches

He is 3 inches taller

63 - 60 = 3 inches

Answer: x=16

Step-by-step explanation:

Knowing that the sideways lines are parallels, the corner of them are equal to each other. Using this information, we can create an equation.

6x-12=4x+20

2x-12=20

2x=32

x=16.

Answer= 16

6x-12=4x+20 then you subtract 4 from 6 because they have the same variable which gives you..
2x-12=20 then you distribute the 12. so 12+12 cancels out and then 20+12 gives you 32 so..
2x=32 then you divide both sides by 2 which gives you..

Select all that apply. *Choose 3*

The diagram represents a right rectangular prism with dimensions labeled as algebraic expressions.Which

Answers

Answer:

3rd Option

Step-by-step explanation:

Volume = (2x-5)*(2x+5)*3x

Volume = (4x^2 + 10x - 10x -25)*3x

Volume = 12x^3 +30x^2 -30x^2 - 75x

Volume = 12x^3 - 75x

The expressions represent the volume of the prism is

V = 12x^2 - 75x

The volume of a rectangular prism

The formula for calculating the volume of rectangular prism is expressed as:

V = lwh

l is the length

w is the width

h is the height

Given the following

l = 2x + 5

w = 2x - 5

h = 3x

V =  3x(2x+5)(2x-5)

V = 3x(4x^2 - 25)

V = 12x^2 - 75x

Hence the expressions represent the volume of the prism is

V = 12x^2 - 75x

Answer:square root of one hundred thirty (11.401)  square root of hundred eleven eighths (10.573)

Step-by-step explanation:   (11.401) > (10.573) i think i answered it, The choice of wording was a bit hard to understand.

The correct answer would be option (A) the square root of one hundred thirty > one hundred eleven eighths.

What is inequality?

Inequality is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are not equal.

the square root of one hundred thirty = √130

the square root of one hundred thirty =  (11.401)  

the square root of hundred eleven eighths = √118

the square root of hundred eleven eighths =  (10.862)

Since (11.401) is greater than (10.862)

So (11.401) > (10.862)

Therefore, the square root of one hundred thirty > one hundred eleven eighths.
