okay everybody, everybody for him or her self! What's 1+1? The two lucky people who answers this question will get brainlest!

Answer:

(using substitution to solve the problem)

x=y-3

2x+y=12

2(y-3)+y=12

2y-6+y=12

3y=18

y=6

y=6

x=6-3

= (3, 6)

Step-by-step explanation:

using substitution, substitute the x in the second equation to y-3, to find the value of y. after that distribute the 2 into the parenthesis and collect like terms. once you simplify, you have the value of y, so substitute the value of y into the first equation to find x. once you have both values put them in the ordered pair form and you're done.

Answer:

240 people

Step-by-step explanation:

[tex]\frac{60}{25} =\frac{x}{100}[/tex] (x represents people)

60×100= 6000 , 25 × [tex]x[/tex] = 25[tex]x[/tex]

[tex]\frac{25x}{25x}=x[/tex]        [tex]\frac{6000}{25x} = 240[/tex]

x=240

Answer:

103 & 77 degrees

Step-by-step explanation:

Supplements add up to 180 degrees.

I started at 90 & did:

90 + 13 = 103

(Because 13 * 2 is 26, but if you subtract 26 then the supplement will be 52 away & not 26)

180 - 103 = 77

103 - 77 = 26

Hope this helped. :)

Given:

In circle D, the measure of angle ADC is 108 degrees.

To find:

The measure of angle ABC.

Solution:

Central angle theorem: According to this theorem, the measure of central angle of an arc is twice of the measure of inscribed angle on that arc.

Using the Central angle theorem, we get

[tex]m\angle ADC=2\times m\angle ABC[/tex]

[tex]108^\circ=2\times m\angle ABC[/tex]

[tex]\dfrac{108^\circ}{2}= m\angle ABC[/tex]

[tex]54^\circ= m\angle ABC[/tex]

Therefore, the measure of angle ABC is 54 degrees.

Answer:

-4 is less than 17 and the "less than" symbol is <. however, this situation can also be expressed by -4 being "less than or equal to" 17 (this symbol is < with a line underneath it)

-4 < 17 OR -14 "less than or equal to" 17

Answer:

60

Step-by-step explanation:

10×2=20÷2=10×2=20 goes for the two top ones

20×2=40÷2=20×2=40 goes for the two bottom ones

40+20=60 is the answer

Answer:

60ft^2

Step-by-step explanation:

Split the area into two large triangles, the right and the left.

The base for the triangle is 10ft+20ft =30ft and we know the height is 2.

Since A=bh*1/2, A = 30*2*1/2. This equals 30. since there are two of these large triangles and they are equal, just multiply the area by 30.

Answer:

Rectangle and Quadrilateral

Step-by-step explanation:

Hi,

It can't be a rhombus because, in a rhombus, all the sides are equal. The same goes for a square so those two aren't correct. It is a rectangle and in a Quadrilateral, the sides are straight. So your two answers are a rectangle and a Quadrilateral.

Answer: Choice B

[tex]\overset\frown{AB} ; \ 115[/tex]

=================================================

Explanation:

The measure of any minor arc is always less than 180 degrees. So it will have a smaller measure than a semicircle. Arc ADB is over 180 degrees, so we can rule that out. Minor arc AB is the measure from A to B following the shorter path along the circle, which would be 115 degrees (the longer path would be 360-115 = 245 degrees)

In other words, the central angle ACB is equal in measure to minor arc AB. Both describe the same basic idea when it comes to circles and their angle measures.

Answer:

Total cost= 369 + 4.5x

x= number of minutes

Step-by-step explanation:

Giving the following information:

Fixed cost= $369

Unitary variable cost per minute= $4.5

To calculate the total cost after x minutes, we need to use the following formula:

Total cost= 369 + 4.5x

x= number of minutes

For example, for 45 minutes:

Total cost= 369 + 4.5*45

Total cost= $571.5

Answer:

75.4 ft³

Step-by-step explanation:

Volume of a cone = πr²h/3

π = 3.14

radius, r = diameter / 2

= 6ft/2

= 3 ft

Height, h = 8 ft

Volume of a cone = πr²h/3

= (3.14 * (3)² * 8) / 3

= (3.14 * 9 * 8) / 3

= 226.08 / 3

= 75.36

Volume of a cone = 75.36 ft³

Approximately to the nearest tenth = 75.4 ft³

Correct question is;

What function is the inverse of the exponential function y = 1.5^(x)?

Answer:

y = log_1.5_x

Step-by-step explanation:

The inverse of exponential functions is usually written in form of logarithm.

For example inverse of y = p^(x) will be written as; y = log_p_(x)

Similarly applying this same pattern to our exponential function y = 1.5^(x), we have the inverse as;

y = log_1.5_x
