Answer:

Let J represent the number of tickets Jose sells. Let M represent the number of tickets Mark sells. Make equations, if Mark sells 15 more tickets than Jose, the equation is J+15=M. Because we know that in between both of them they sell 63 raffle tickets, then M+J=63. Now plug in the value of M (J+15) into M+J=63. And you get (J+15)+J=63, which is 2J+15=63. Subtract 15 from both sides and get 2J=48. Now divide 48 by 2, J=24. So now you know Jose sold 24 tickets, and to find how many Mark sold, plug in 24 into J+15=M and get 24+15=M where M is 39. Now check, 24+39=63. So Mark sold 39 tickets and Jose sold 24.

Answer:

Step-by-step explanation:

40a²b =  2* 2 * 2 * 5 * a² * b      =  2³ * 5 * a² * b

48ab⁴ = 2 * 2 * 2 * 2 * 3 * a *b⁴  = 2⁴ *  3 * a * b⁴

LCM = 2⁴ * 3 * 5 * a² * b⁴

       = 16 * 3 * 5 * a² * b⁴

       = 240a²b⁴

Answer:

B = C = 70°

Step-by-step explanation:

In Triangle ABC, angle A measures 40 degrees.

We need to find the possible angle measures for B and C if ABC is in isosceles triangle.

For an isosceles triangle, two sides of a triangle are equal. We know that if two sides are equal, the corresponding angles are equal. Let equal angles are x. The sum of an isosceles triangle is equal to 180 degrees. So,

40 + x +x = 180

40 + 2 x = 180

2x = 140

x = 70 degrees

So, the possible angle measures for B and C is equal to 70°.

Answer:

X > 7

Step-by-step explanation:

Answer: 12 millimeters.

Step-by-step explanation:

Answer:

B

Step-by-step explanation:

Givens

a^2 + b^2 = c^2

a = 4x

b = x + 2

c = 3x + 4

Solution

(4x)^2 + (x + 2)^2 = (3x + 4)^3                  Remove all the brackets.

16x^2 + x^2 + 4x + 4 = 9x^2 + 24x + 16  Collect like terms on the left

17x^2 + 4x + 4 = 9x^2 + 24x + 16            Subtract the terms on the right

8x^2 - 20x - 12 = 0

This factors into

(4x - 12)(2x + 1)

There are 2 answers

4x - 12 = 0

4x = 12

x = 12/4

x = 3

or

2x + 1 = 0

2x = - 1

x = - 1/2

You have to look at x = -1/2 carefully. The problem is that 4x = 4*(-1/2) = - 2 which is not possible in Euclidean Geometry.

So the only answer is x = 3

Answer:

I got x = 1

Step-by-step explanation:

First to isolate the variable you add 3 to both sides which will give you 1/2x is less than or equal to 2. Then divide both sides by 1/2 and you will get x = 1. To check the answer I just did:    

[tex]1/2(1) -3 \leq -1\\1/2 -3\leq -1\\-2.5\leq -1[/tex]

And since -2.5 is less than -1 this statement is true. x does in fact equal 1

The true statement about the graph is that it shows a proportional relationship

From the question, we have the following parameters that can be used in our computation:

The graph (added as an attachment)

On the graph, we have the following observations and highlights

Using the above as a guide, we have the following:

A graph that has the above features is not just a linear equation, it is a proportional linear equation

This means that it has a unit rate

And the unit rate is

Unit rate = 200/8

Unit rate = 25

Hence, the graph shows a proportional relationship

Answer:

Domain: 1,-2,-1, 1

Range: -2,0,2,3

Answer: x=4,  y=-1

Step-by-step explanation:

Multiply the second equation by 3:

18x+9y=63

Then summarize  both equations 18x+9y+3x-9y=21+63

21x=84 => x=4

use x=4 in any of initial equations ,for instance in first one:

3*4-9*y=21

12-9*y=21

9y=12-21

9y=-9

y=-1
