Step-by-step explanation:

80 Divied by 4 is 20

SO Each Pair Is 20

7 x 20 = 140

Answer:

140

Step-by-step explanation:

It would be $20 a pair.

Step-by-step explanation:

linear equations have one solution are:-

5x - 1 = 3(x + 11)

4(x – 6) + 4 = 2(x - 3)

2(x – 4) = 5(x – 3) + 3

Answer:

The linear equations that have one solution are:

5x - 1 = 3(x + 11)

4(x – 6) + 4 = 2(x - 3)

2(x – 4) = 5(x – 3) + 3

3600/30/16=15/2=7 1/2

Answer:

The inverse with respect to addition; the opposite. The additive inverse of 12 is −12. The definition of an additive inverse is the number needed to bring a negative number to zero. An example of an additive inverse is the number 30 when added to -30. So the additive inverse of -10 is 10

Step-by-step explanation:

Answer: 10

Step-by-step explanation:

To find the additive inverse of a number, all we should do is change its sign. Thus, the additive inverse of a positive number is a negative number, and the additive inverse of a negative number is a positive one. So the additive inverse of -10, which is negative, is positive 10, or just 10.

Answer: -9 degrees Fahrenheit

Step-by-step explanation:

Given: Temperature at 6:00 AM = -12 degrees Fahrenheit

Temperature increased each hour = [tex]\dfrac12[/tex] degrees Fahrenheit

Temperature increase in 6 hours = [tex]6\times\dfrac12=3\text{ degrees Fahrenheit}[/tex]

Temperature at noon = Temperature at 6:00 AM+Temperature increase in 6 hours

= -12+3 degrees Fahrenheit

= -9 degrees Fahrenheit

Hence, the temperature in degrees Fahrenheit at noon= -9 degrees Fahrenheit

Answer:

1. Domain: [0,120] Range: [0,300]

2. f(30) = 200; After 30 minutes, the altitude of the balloon is 200 feet.

3. x = 10; When the altitude of the balloon is 100 feet, the time has passed is equal to 10 minutes.

4. at 20-40 minutes

5. 70 minutes

6. x: {40 ≤ x ≤ 90}

Step-by-step explanation:

1. The line is between 0 and 120 on the x-axis and is between 0 and 300 on the y-axis.

2. When x = 30, y equals 200.

3. When y = 100, x equals 10.

4. The line stays on 200 for 20 minutes, between 20 and 40.

5. Between 30 and 100 minutes, the altitude is greater than 200.

6. All x values between 40 and 90 (including 40 and 90 too) matches with 300 as their y-coordinate.

Answer:

471.25

Step-by-step explanation:

A volume of a box is equal to length x width x height (abbreviated lwh). The given was: 14 & 1/2 inches long, 5 inches high, and 6 1/2 inches wide. So, all you have to do is multiply the given (I know it sounds too easy, but that's it):

14.5 * 5 * 6.5 = 471.25

So, the volume of the box is 471.25 inches cubed.

I hope that this helped & good luck!

Answer:

0.833

Step-by-step explanation:

5/6 = 0.83333333

Only the 8 and 3's are Significant Figures, so the answer is 0.833.

Given:

The diagram shows two right-angled triangles OAB  and OCD.

To find:

The length of BD.

Solution:

Let the length of BD is x.

In triangle OAB and OCD,

[tex]\angle AOB\cong \angle COD[/tex]           (Common angle)

[tex]\angle ABO\cong \angle CDO[/tex]           (Right angle)

[tex]\Delta OAB\sim OCD[/tex]                           (By AA property of similarity)

We know that, the corresponding sides of similar triangles are proportional. So,

[tex]\dfrac{AB}{CD}=\dfrac{OB}{OD}[/tex]

[tex]\dfrac{4}{7}=\dfrac{14}{14+x}[/tex]

[tex]4(14+x)=14(7)[/tex]

[tex]56+4x=98[/tex]

Subtracting 56 from both sides, we get

[tex]4x=98-56[/tex]

[tex]4x=42[/tex]

[tex]x=\dfrac{42}{4}[/tex]

[tex]x=10.5[/tex]

Therefore, the length of BD is 10.5 cm.

Answer:

yep, absolutely mess

Answer:

Area = 144 inches2

or

Area = 1 feet2

Steps:

1.5 feet = 18 inches

Area =  l × w

=  8 × 18

=  144 inches2

or

8 inches = 0.66666666666667 feet

Area =  l × w

=  0.66666666666667 × 1.5

=  1 feet2

Answer:

8[tex]x^{2}[/tex] + 3 + -6x

Step-by-step explanation:

First we need to find the like terms so that we could add them. In this case the like terms are,

1. 6x , -2x , -10x

So, these are the only terms that we can add in this expression.

Hence,

=> 8[tex]x^{2}[/tex] + 3 + (6x - 2x - 10x)

=> 8[tex]x^{2}[/tex] + 3 + -6x

And this is as simple as this expression can go until we find the value of "x" which is not yet told.

Hope my answer helped.
