Answers

Answer:

x = 60

Step-by-step explanation:

subtract 7 from both sides:

7 + x - 7 = 2x - 53 - 7

Simplify:

x = 2x - 60

Subtract 2x from both sides:

x - 2x = 2x  - 60 - 2x

Simplify:

-x = -60

Divide by -1=

-x/-1 = -60/1

X = 60

Margo added three multi-digit decimal numbers. The first number was 5.19. The second number was 10 times the first number. The third number was 10 times the second number. What was the sum?

Answers

Answer: 576.09

Step-by-step explanation:

First number = 5.19.

The second number was 10 times the first number which will be:

= 5.19 × 10

= 51.9

The third number was 10 times the second number. Thus will be:

= 51.9 × 10

= 519

The sum of the numbers will be:

= 1st number + 2nd number + 3rd number

= 5.19 + 51.9 + 519

= 576.09

The sum of two numbers is 46 and their

So 13 and 33
13

Answer:

B. 13

Step-by-step explanation:

We have two unknown numbers, let's have two variables for these two unknown numbers, X and Y.

"The sum of two numbers is 46 and their difference is 20."

Meaning we have two equations :

X + Y = 46

X - Y = 20

Looking at the last part of "their difference is 20." We can assume X = Y + 20

So substitute the assumed equation into X + Y = 46

(Y + 20) + Y = 46

2y + 20 = 46

Subtract 20 from both sides :

2y = 26

Divide 2 by both sides :

y = 13

There you go.

The difference in the price of 2 backpacks is $19.30. If one backpack costs $39.00, which of the answer choices could represent the price of the other backpack?

Answers

Answer:

$19.70 OR $58.30

Step-by-step explanation:

I say either or because I can't see the answer choices.

Its either adding or subtracting from the one backpack we know is $39.00

If we know the difference between the two is 19.30

39.00+19.30 = 58.30

39.00-19.30= 19.70

Use the Distributive Property to solve the equation.
- 8(x + 7) = 16
Apply the Distributive Property and simplify.
- 8(x + 7) = 16
- 8x + = 16

Answers

Answer:

x= - 9

Step-by-step explanation:

- 8(x +7) = 16-8x - 56 = 16 -8x = 16 + 56-8x = 72x = 72 ÷ (-8) x = -9

Hey there!

Use the Distributive Property and simplify:

-8(x+7)=16

-8x-56=16

Notice we write -8 right next to x.

Add 56 to both sides:

-8x=16+56

-8x=72

Divide both sides by -8:

x=-9

Hope everything is clear.

Isabella and her cousin Rodrigo have the same birthday but isabella is 15 years older than Rodrigo the equation y= x + 15 represents isabella's age y, when Rodrigo is x years old what is the answer?.

Answers

Answer:

The answer is below

Step-by-step explanation:

Isabella and her cousin rodrigo have the same birthday, but isabella is 15 years older than rodrigo is x years old. which table of value shows this relationship

Solution:

Let x represent Rodrigo's age and let y represent Isabella's age. Since Isabella is 15 years older than Rodrigo, hence her age is given by the equation:

y = x + 15

You can use a table to represent the relationship between their ages. Let us find the corresponding Isabella age for the following Rodrigo age.

Rodrigo:     10         20            30

Isabella:      25        35           45

When x = 10:   y = x + 15 = 10 + 15 = 25

When x = 20:   y = x + 15 = 20 + 15 = 35

When x = 30:   y = x + 15 = 30 + 15 = 45

Serenity invested $3,100 in an account paying an interest rate of 2.9% compounded continuously. Assuming no deposits or withdrawals are made, how much money, to the nearest dollar, would be in the account after 12 years?

Answers

Answer:

$4179

Step-by-step explanation:

3,100*.029= 89.9

89.9*12=1,078.80

3,100+1,078.80=4,178.80

4,178.80 rounded to the nearest dollar= 4179

The amount of money in the account after 12 years would be $4,371.

What is Compound interest?

Compound interest is defined as interest paid on the original principal and the interest earned on the interest of the principal.

To calculate the amount of money in the account after 12 years, we need to use the formula for continuously compounded interest, which is:

A = P[tex]e^{rt}[/tex]

where A is the final amount, P is the principal (initial amount invested), r is the annual interest rate, and t is the number of years the money is invested.

In this case, the initial amount invested is $3,100, the annual interest rate is 2.9%, and the number of years is 12.

Plugging these values into the formula, we get:

A = $3,100 × [tex]e^{0.029 \times 12)[/tex]

A = $3,100 × [tex]e^{0.348}[/tex]

A = $3,100 × 1.41

A = $4,371

Therefore, the amount of money in the account after 12 years, to the nearest dollar, would be $4,371.

What does the quadratic function
f(x) = x2 - 6x + 8 look like when it is
rewritten in the form f(x) = a(x − p)2 +q?

Answers

Answer:

f(x) = (x -3)^2 - 1

Step-by-step explanation:

f(x) = x^2 - 6x + 8

a = 1, b = -6 and c = 8

So we are finding half of the b equation (ignore the negative sign)

Half of 6 is 3, so we are going to square 3 (3^2 = 9) and add 9 to the left side and subtract 9 to the right side

(x) = (x^2 - 6x + 9) + (8 - 9)

You can tell the polynomial is a perfect square, so we will have to factor it using the perfect square method

(x^2 - 6x + 9)

square toot of x^2 is x and square root of 9 is 3 and the operation sign after the a number is a minus sign

(x -3)^2

Don't forget the rest of the equation from before

(x -3)^2 + (8 - 9)

(x -3)^2 - 1

So the equation is f(x) = (x -3)^2 - 1

Anais bought 4 1/2 yards of ribbon. She had 3 feet 8 inches of ribbon left after trimming some curtains. How many inches of ribbon did anais use to trim the curtains

Answers

Answer:

First convert all numbers into inches since that is the answer being solved for.

1 yard =36 inches

4.5 x 36 = 1,620 inches

1 foot = 12 inches

3 x 12 = 36 inches

36 + 8 = 44 inches

Now take 1,620 inches (starting ribbon measure) and subtract 44 inches (what was left over) to get the inches used to trim curtains.

1,620 inches - 44inches =

1,576 inches were used to trim the curtains.

Read the passage by J. Robert Oppenheimer about the potential use of an atomic weapon during World War II.You have asked us to comment on the initial use of the new weapon. . . . We recognize our obligation to our nation to use the weapons to help save American lives in the Japanese war. . . .The opinions of our scientific colleagues on the initial use of these weapons are not unanimous: they range from the proposal of a purely technical demonstration to that of the military application best designed to induce surrender. Those who advocate a purely technical demonstration would wish to outlaw the use of atomic weapons, and have feared that if we use the weapons now our position in future negotiations will be prejudiced. Others emphasize the opportunity of saving American lives by immediate military use, and believe that such use will improve the international prospects, in that they are more concerned with the prevention of war than with the elimination of this specific weapon. We find ourselves closer to these latter views; we can propose no technical demonstration likely to bring an end to the war; we see no acceptable alternative to direct military use.J. Robert Oppenheimer,June 16, 1945Which statement does this passage support?The scientists are divided on the best way to implement the atomic weapon to help end the war.All of the scientists believe that the atomic weapon they built needs to be used in Japan to end the war.The scientists fear that the atomic weapon is too dangerous for any type of use and believe that it should never be detonated.All of the scientists agree that the atomic weapon should be used only to demonstrate the military might of the United States.
