To mail a package, UPS charges a $7 flat fee and $2 per pound. FedEx charges
a $5 flat fee and $3 per pound.

Answers

Answer:

The package where they charge the same must cost $2

Step-by-step explanation:

Given

UPS

[tex]Flat = \$7[/tex]

[tex]Additional = \$2/lb[/tex]

FedEx

[tex]Flat = \$5[/tex]

[tex]Additional = \$3/lb[/tex]

Required

What pound do both charges are the same

Represent the charges with x;

For UPS, it can be written as:

[tex]Charges = 7 +2x[/tex]

For FedEx:

It is:

[tex]Charges = 5 + 3x[/tex]

Equate these charges together

[tex]5 + 3x = 7 + 2x[/tex]

Collect Like Terms

[tex]3x - 2x = 7 - 5[/tex]

A weather balloon ascended from an elevation of 18 feet below sea level to an elevation 19 1/2 feet above sea level. What distance dd the weather balloon rise?

Answers

Answer:

The ballon rose a distance of 37 1/2 feet

Step-by-step explanation:

Here, we are interested in calculating the level of ascent of the weather balloon.

From the question, we are told that the ballon made a transition from below the sea to above the sea.

Now to calculate the total distance, we shall

If each interior angle of a regular polygon is 144 degrees. Find the number of sides in it.

Answers

Answer:

10

Step-by-step explanation:

In a polygon

interior angle + interior angle = 180°, thus

exterior angle = 180° - 144° = 36°

The sum of the exterior angles in a polygon = 360°, thus

number of sides = [tex]\frac{360}{36}[/tex] = 10

Answer:

10 sides

Step-by-step explanation:

A decagon is a 10-sided polygon, with 10 interior angles, and 10 vertices which is where the sides meet. A regular decagon has 10 equal-length sides and equal-measure interior angles. Each angle measures 144° and they all add up to 1,440°.

Answer:

See Explanation

Step-by-step explanation:

m = 46° (vertical angles)

j = 92° (vertical angles)

j + k + 46° = 180° (staright line angles)

92° + k + 46° = 180°

138° + k = 180°

k = 180° - 138°

k = 42°

n = 37° + 44° = 81°

At a track meet, the 3 members of a relay race ran a total distance of 3/8 of a mile. if each runner ran the same distance. how far did each person run?​

Answers

Answer:

.125 of a mile

Step-by-step explanation:

If the total distance was 3/8 of a mile and there were 3 runners, then each runner ran ___________________.

Change the 3/8 to a decimal

3/8 = 0.375 of a mile

Since there were 3 runners divide the total distance by 3

0.375/3 = 0.125

Each runner ran 1/8 of a mile or 0.125 of a mile.

What is x? Help please

Answers

X=12 hope I helped:)

Answer:

x = 12

Step-by-step explanation:

For this problem, we can simply drop the parenthesis, combine like terms, and isolate x to find the value of x.  Below is how to do this:

( 4x + 108 ) + ( 2x ) = 180

4x + 108 + 2x = 180

4x + 2x + 108 = 180

6x + 108 = 180

6x = 72

x = 12

Hence, the value of x is 12.

Solve 12 + 12a + 4a = -4

Answers

Answer:

a=-1

Step-by-step explanation:

we need to get a by itself

first combine like terms

12+16a=-4

now we need to get rid of the 12 so subtract it to other side

-16=16a

now divide 16 by -16 which gives you -1=a

Answer: a=-1

12+12a+4a=-4

(Collect like terms)
12+16a=-4

(Move constant to the right-hand side and change it’s sign)
16a=-4-12

(Calculate the difference)
16a=-16

(Divide both sides of the equation by 16)
a=-1
