Step-by-step explanation:

move x to one side and numbers on another side.

9+5<3x+4x. --» 14<7x. --»/7--» x>2

Final answer:

The inequality 9 - 4x < 3x - 5 simplifies to x > 2 after collecting like terms and performing basic algebraic operations. Therefore, the correct answer is B. x > 2.

Explanation:

To solve the inequality 9 - 4x < 3x - 5, we need first to collect like terms on one side. This step involves moving all the x terms to one side of the inequality and the constant terms to the other side.

Let's do this now:

The answer is x > 2, which corresponds to option B.

Original question: What two numbers multiply to get -12 and add to -5.

Answer:

Pairs of numbers (1.772, -6.772) and (-6.772, 1.772).

Step-by-step explanation:

Let [tex]x[/tex] and [tex]y[/tex] be the two numbers, the we know that

(1). [tex]xy=-12[/tex]

and

(2). [tex]x+y=-5[/tex]

We solve for [tex]y[/tex] in equation(2) and substitute this into equation(1)

[tex]y=-(5+x)[/tex]

[tex]xy=-x(x+5)=-12[/tex]

[tex]x^2+5x-12=0[/tex]

This is a quadratic equation, and its solutions are

[tex]x=1.772\\\\x=-6.772[/tex]

we substitute these two solutions into equation(1) and find the corresponding [tex]y[/tex] values:

[tex](1.772)y=-12\: \therefore y=-6.772[/tex]

[tex](-6.772)y=-12 \: \therefore y=1.772[/tex]

Thus we have two pairs of numbers which multiply to give -12 and add to give -5

[tex](1.772, -6.772)[/tex] and [tex](-6.772, 1.772).[/tex]

Answer:

1990

Step-by-step explanation:

The number of banks in 1970 is 18,137, in 1990 is 3, and in 2010 is 7,250.

(a) Since 1970 is 70 years after 1900,

use the function f(x) = 81.8x + 12,361 for the years before 1990 (when x < 90).

f(70) = 81.8 * 70 + 12,361

        = 5776 + 12,361

        = 18,137

The number of banks in 1970 is 18,137.

(b) Since 1990 is exactly 90 years after 1900,

use the other part of the function f(x) = 3 for the years between 1990 and 2010.

f(90) = 3

The number of banks in 1990 is 3.

(c) Since 2010 is 110 years after 1900, use the function

f(x) = -376.4x + 48,685 for the years after 290 (when x > 290).

f(110) = -376.4 * 110 + 48,685

        = -41404 + 48,685

         = 7250

The number of banks in 2010 is 7,250.

So, the number of banks are 18,137, 3 and 7,250.

Step-by-step explanation:

I just completed the test and got it correct.

Bill's and Mary's watches will match once a year on a non-leap year and twice a year on a leap year since Bill's watch loses 4 minutes per day. After 360 days, Bill's watch will be exactly 24 hours behind Mary's.

You asked how many times a year Mary's watch (which keeps perfect time) and Bill's watch (which loses 4 minutes a day) would match if they were both set at midnight on January 1. This is a mathematical problem involving the concept of elapsed time.

Since Bill's watch loses 4 minutes per day, after 1 day, there will be a 4-minute difference between the two watches. As this pattern continues, we calculate how many days it will take for Bill's watch to lose an entire 24-hour cycle (1440 minutes) since 1440 minutes divided by 4 minutes/day equals 360 days. Therefore, Bill's watch would match Mary's watch exactly one more time, 361 days after both watches were set, which would be on the next New Year's Eve, just before both watches hit midnight.

However, this scenario would only occur in a non-leap year. During a leap year, Bill's watch would be 4 minutes slow on December 30th instead of on December 31st, so Bill's watch would match Mary's watch two times in a leap year, once on January 1st and again on December 30th. In conclusion, Bill's and Mary's watches match once a year during a non-leap year and twice during a leap year.

Step-by-step explanation: The answer is 1.4 because the number you were using to round was lower than five.

Final answer:

The number 1.428571429 rounded to the nearest tenth is 1.4, as the hundredth's place digit is less than 5.

Explanation:

To round the number 1.428571429 to the nearest tenth, we look at the first digit after the tenth's place, which is the hundredth's place. If this digit is 5 or greater, we round up. If it's less than 5, we do not round up. In this case, the hundredth's digit is 2, which is less than 5. Therefore, the number 1.428571429 rounded to the nearest tenth is 1.4. This process of rounding to the nearest tenth simplifies numbers while maintaining their approximate value, aiding in concise representation and easier comprehension of numerical data in various contexts.

Step-by-step explanation:

The side of the square = x + 2, thus area is equal to

(x + 2)² ← expand using FOIL

= x² + 4x + 4

Given area = 7 then

x² + 4x + 4 = 7 ( subtract 4 from both sides )

x² + 4x = 3 ← as required

Answer:

the area of the square ABCD = 7

on the other hand, the area of the square ABCD = (2+x)² = x² + 4x + 4

then x² + 4x + 4 = 7

then x² + 4x + 4 = 4 + 3

Step-by-step explanation:

It takes twenty minutes to finish a quarter of one level. Which indicates that it would take one hour and twenty minutes to finish said level by simply multiplying twenty by four.

George will complete a level on his computer games in 1 1/3 of the hours.

The ratio is defined as a relationship between two quantities, it is expressed as one divided by the other.

We have been given that he finished 1/4 of a level on his computer games in 1/3 of an hour at this rate.

Let x the number of hours will it take to complete on a level

According to the given question, we can write the ratio would be as:

1/4 of a level : 1/3 of an hour = 1 level : x hour

⇒ (1/4) / (1/3) = 1/x

Apply the cross-multiplication operation,

⇒ x = (1/3) × 4

⇒ x = 4/3

⇒ x = 1 1/3

Therefore, there will be 1 1/3 of the hours it takes to complete a level.

9 3/6 ⇒ 19/2

3 4/6 ⇒ 11/3

Step-by-step explanation:

A fraction greater than one is an improper fraction.

[tex]9\frac{3}{6}[/tex] when converted into an improper fraction is

[tex]9\frac{3}{6} =9+\frac{3}{6} \\\\=\frac{9*6}{6}+ \frac{3}{6}\\\\ =\frac{54}{6}+ \frac{3}{6}=\frac{57}{6}\\\\ =\boxed{\frac{19}{2}. }[/tex]

[tex]3\frac{4}{6}[/tex] when converted to a fraction is

[tex]3\frac{4}{6}=3+\frac{4}{6}\\\\=\frac{3*6}{6}+ \frac{4}{\\\\6}\\\\=\frac{18}{6}+\frac{4}{6}=\frac{22}{6}\\\\=\boxed{\frac{11}{3}. }[/tex]

Thus fractions [tex]9\frac{3}{6}[/tex] and [tex]3\frac{4}{6}[/tex] when converted to fractions greater than one are [tex]\frac{19}{2}[/tex] and [tex]\frac{11}{3}[/tex] respectively.

9 3/6 cups of pancake batter is [tex]\( \frac{19}{2} \)[/tex]and 3 4/6 cups is [tex]\( \frac{11}{3} \)[/tex].

Step 1:

Convert the mixed number 9 3/6 to an improper fraction:

[tex]\[ 9 \frac{3}{6} = \frac{(9 \times 6) + 3}{6} = \frac{54 + 3}{6} = \frac{57}{6} \][/tex]

Step 2:

Simplify the fraction:

[tex]\[ \frac{57}{6} = \frac{19 \times 3}{2 \times 3} = \frac{19}{2} \][/tex]

So, 9 3/6 cups of pancake batter is equivalent to the improper fraction [tex]\( \frac{19}{2} \).[/tex]

Step 3:

Now, convert the mixed number 3 4/6 to an improper fraction:

[tex]\[ 3 \frac{4}{6} = \frac{(3 \times 6) + 4}{6} = \frac{18 + 4}{6} = \frac{22}{6} \][/tex]

Step 4:

Simplify the fraction:

[tex]\[ \frac{22}{6} = \frac{11 \times 2}{3 \times 2} = \frac{11}{3} \][/tex]

So, 3 4/6 cups of pancake batter is equivalent to the improper fraction [tex]\( \frac{11}{3} \).[/tex]

Therefore, each mixed number, when expressed as a fraction greater than one, is [tex]\( \frac{19}{2} \)[/tex] and [tex]\( \frac{11}{3} \)[/tex], respectively.
