I need help with this math problem!!
Vesnalui [34]
In order to find which one is or isn't, you need to solve for the value of 'x'. 
2x + 15 = 35 
2x = 20
x = 10 

Substitute x =10, into equation. If each side are not the same (i.e. 0=2), then that's the equation that is not equivalent,

Answer is B
Double check this. Chur! :)

Hope this makes sense.

At a football game, Ben purchased x hot dogs and y drinks. He spent a total of $30.70. The equation below describes the relation
Yuki888 [10]
So I had to reread this about 3 times before it finally clicked, I've never done a problem like this before. An ordered pair is organized like so: (x-coordinate, y-coordinate) Meaning x=4 and y=6. If x=hot dogs and y=drinks then this means that Ben purchased 4 hot dogs and 6 drinks at the game. 

Hope this helps!! (:

Finish solving the system of equations –9.5x – 2.5y = –4.3 and 7x + 2.5y = 0.8 using the linear combination method.
trasher [3.6K]

Answer:

The value of x is 1.4 and y is -3.6

Step-by-step explanation:

The steps are :

- 9.5x - 2.5y =  - 4.3 -  -  - (1)

7x + 2.5y = 0.8 -  -  - (2)

(1) + (2)

- 9.5x + 7x - 2.5y + 2.5y =  - 4.3 + 0.8

- 2.5x =  - 3.5

x =  \frac{7}{5}  \: or \: 1.4

substitute \: x = 1.4 \: into \: (2)

7(1.4) + 2.5y = 0.8

9.8 + 2.5y = 0.8

2.5y =  - 9

y =  -  \frac{18}{5}  \: or \:  - 3.6

The histogram shows the number of laps completed by swimmers on a team during practice.
Romashka [77]

Answer:

A) 10-14

B) 45

C) 6.7%

Step-by-step explanation:

A) The interval that contain the most values can be gotten by looking at the histogram and selecting the interval with the highest frequency. Hence the interval 10-14 contains the most values because it has a frequency of 20.

B)The total number of swimmers is gotten by summing all the frequency of each individual lap. Hence:

Total swimmers on team = 10 + 12 + 20 + 0 + 3 = 45 swimmers

C) The percentage of swimmers who swam more than 14 laps = (number of swimmers that swam more than 14 laps/total swimmers) * 100%

The percentage of swimmers who swam more than 14 laps = [(0 + 3)/45] * 100% = (3/45) * 100% = 6.7%

What similarity property, if any, can be used to show that the following two triangles are similar.
Reil [10]
They both have right angles and have the same angles overall. Essentially they are the same size, one is just expanded bigger than the other. It might be dilation. The inside line so indicate the similarity in angle sizes.
