Answer:

The answer would be 6.7b + 2

Step-by-step explanation:

In order to simplify this, simply add the like terms together.

3.8b + 2.9b = 6.7b

-7 + 9 = 2

Now just put those two together

6.7b + 2

1. Are the ratios, 8/12 and 10/25 proportional? Please explain. I will give brainliest for the best explanation.

Marina86 [1]

Answer:

1. No

2. 1,050 bushels of corn

Step-by-step explanation:

1. A number is proportional if it has a constant ratio to another quantity.

8/12 and 10/25 do not.

2. An acre will produce $\frac{750}{10}$ bushels of corn.

750 divided by 10 is 75. <u>This is 75 bushels per acre.</u>

Then you would multiply 75 and 14.

This equals 1,050 bushels of corn.

At the end of a year, the gross debt of a country stood at about $15 trillion. Express this amount in dollars per person, ass

Ilia_Sergeevich [38]

Answer:

The country's debt is $ 48,543.68 per person.

Step-by-step explanation:

Given that at the end of a year, the gross debt of a country stood at about $ 15 trillion, to determine this amount in dollars per person, assuming that the population of the country is about 309 million, the following calculation must be done:

15 trillion = 15,000,000,000,000

15,000,000,000,000 / 309,000,000 = X

15,000,000 / 309 = X

48,543.68 = X

Therefore, the country's debt is $ 48,543.68 per person.

Solve for x under the assumption that x > 0. Enter your answer in interval notation using grouping symbols.

Delicious77 [7]

<span>Starting with x−24/x<10 multiply everything by x. x^2-24<10x Subtract 10x from both sides. x^2-10x-24 < 0 Factor. (x-12)(x+2) < 0 (x+2) is always positive since x > 0, but (x-12) is negative when x is a value between 0 and 12. This negative value for (x-12) satisfies that the left side is less than 0. Thus the solution set for x is (0,12).</span>

Factor out the GCF from the given polynomial. 10^3 + 16^2 - 18x 10^3 + 16^2 - 18x = (Type your answer in factored form.)

Vesna [10]

Correct question is;

Factor out the GCF from the given polynomial. 10x³ + 16x² - 18x. (Type your answer in factored form.)

Answer:

GCF = 5x² + 8x - 9

Step-by-step explanation:

The given polynomial is;

10x³ + 16x² - 18x

First thing is to inspect the coefficients and see the greatest number that all three can be divided by evenly without remainder.

The greatest number is 2.

Secondly let's inspect the variables to see what we can factor out.

They all contain x. Thus, x is a factor.

Thus, we will divide each term by 2x to obtain the GCF of the polynomial.

GCF = (10x³/2x) + (16x²/2x) - (18x/2x)

GCF = 5x² + 8x - 9
