How do I simplify -4(3x + 2y) + 6( -2x - 5y)???

Answer:

The U.S. population 65 and older is now the largest in terms of size and percent of the population, compared with any previous census, according to a new 2010 Census brief [PDF] released today from the U.S. Census Bureau on the nation's older population. The group grew at a faster rate than the total population between 2000 and 2010.

According to the 2010 Census, there were 40.3 million people 65 and older on April 1, 2010, increasing by 5.3 million since the 2000 Census when this population numbered 35.0 million. The percentage of the population 65 and older also increased during the previous decade. In 2010, the older population represented 13.0 percent of the total population, an increase from 12.4 percent in 2000.

65 and Older Population Grew Faster than Total Population

Between 2000 and 2010, the population 65 and older grew 15.1 percent, while the total U.S. population grew 9.7 percent. The opposite happened between 1990 and 2000 when the growth of the older population was slower than the growth of the total population, with growth rates of 12.0 percent and 13.2 percent, respectively.

Population Size and Growth Varied Among the Older Age Groups

Examining the growth of 10-year age groups within the older population shows that 85- to 94-year-olds experienced the fastest growth between 2000 and 2010. This group grew by 29.9 percent, increasing from 3.9 million to 5.1 million.

Among five-year age groups in the older population, 65- to 69-year-olds grew the fastest. This age group grew by 30.4 percent, rising from 9.5 million to 12.4 million. The 65- to 69-year-old group is expected to grow more rapidly over the next decade as the first baby boomers start turning 65 in 2011.

The only older population age group to decline between 2000 and 2010 was the 75- to 79-year-old age group. This group decreased by 1.3 percent from 7.4 million to 7.3 million. The changes in this group mainly reflect the relatively low number of births during the early 1930s as fewer numbers of people entered these ages between 2000 and 2010.

Answer:

3500

Step-by-step explanation:

Hello, you need to eliminate fractions in numbers in such questions. So you have to round. If we round the number 45, we get 50. We don't need to round 50 because 50 has no fractions.

1 - 45 - - > 50

2- 50 - - > no change

3- 50 × 50 = 50² = 3500

Step-by-step explanation:

The amount Levi spends on this skateboard is $148.39.

Tax is an amount levied on goods and services by the government. Taxes increases the price of goods and services.

The amount Levi spends on this skateboard = value of the tax + cost of the skateboard

value of the tax = 6% x $139.99

0,06 x $139.99 = $8.40

The amount Levi spends on this skateboard = $8.40 + $139.99 = $148.39

Answer:

A & C

Step-by-step explanation:

To find the two expressions that are equivalent to 6.5 ÷ 1.3, you need to solve all of them until you get the two expressions that have a quotient of 5.

Let's begin solving!

65 ÷ 13  = 5

So now we know that A is one of our answers

65 ÷ 130 = 0.5

Not one of our answers because the quotient is not 5

650 ÷ 130 = 5

This is our other answer! We don't need to solve D because we only needed to find two expressions which are A and C.

Hope this helps you :)

Answers are A and C.

6.5 ÷1.3 = 5

A. 65 ÷ 13 = 5 so yes

B. 65 ÷ 130 = .5 so no

C. 650 ÷ 130 = 5 so yes

D. 650 ÷ 13 = 50 so no

Answer:

The answer is 3/2 x 63

Step-by-step explanation:

3/2*63 = 189 / 2 = 94.5

7/8*63 = 441 / 8 = 55.125

2/3*63 = 126 / 3 = 42

4/5*63 = 252 / 5 = 50.4

Therefore the answer is 3/2 x 63 because it’s product is greater than 63.

Answer:

Step-by-step explanation:

The triangle is isosceles with side WX equal to side WY:

  WX = WY

  9x -11 = 7x -3

  2x = 8 . . . . . add 11-7x

  x = 4

Then the side measures are ...

  WX = WY = 7(4) -3 = 28 -3 = 25

  XY = 4(4) +1 = 16 +1 = 17

Answer:

213.7°

Step-by-step explanation:

The bearing of B from D is angle ADB,  Thus, ∠ADB = arctan(30/45) ≈ 33.7°

The bearing of D from B is that angle plus 180°, Thus, 180° +33.7° = 213.7°

Part A: 135

Part B: 213.7

213.7°

The bearing of B from D is angle ADB,  Thus, ∠ADB = arctan(30/45) ≈ 33.7°

The bearing of D from B is that angle plus 180°, Thus, 180° +33.7° = 213.7°

Answer:

y= 27-6x

Step-by-step explanation:

For the first equation you add 6x on both sides which will leave us at

-y=-27+6x. You then divide both sides by a -1 to make the y positive so then it'll give us the equation y= 27-6x . For the second equation subtract 18x on both sides which will leave us with the equation 3y= 81-18x . Divide each side by 3 to get the y by itself. Then the equation will be y=27-6x

[tex]-6x = -5x -9 \\\\\implies -6x +5x = -9 \\\\\implies -x = -9 \\\\\implies x =9[/tex]

(btw when it just has the "-" that is a line to separate them and for the -x = -9, they are divided by -1 sorry if that confused you before.)

Answer:

x = 9

Step-by-step explanation:

-6x = -5x -9

Answer: x = 48 minutes

Step-by-step explanation:

15 miles/72 min = 0.208 miles/min

(0.208 miles/min)x = 10 miles

x = 48 minutes

Answer:

x=-29/24

y=3/8

Step-by-step explanation:

3x-9y= -7 ---A

2y-6x= 8----B

multiply eq A by 2

6x-18y=-14

-6x+2y=8

Add both equations, so you eliminate x since 6x+(-6x) = 0

-18y+2y= -16y

-14+8=-6

so you have

-16y=-6

y=3/8

now substitute this back to eq B, (you can use eq A as well if you like)

2(3/8)-6x=8

3/4-6x=8

-6x=29/4

x=-29/24

Answer: 100 feet
