4(x-5)=3(x+5)
Multiply the first bracket by 4
(4)(x)=4x
(4)(-5)=-20
Multiply the second bracket by 3
(3)(x)=3x
(3)(5)=15
4x-20=3x+15
Move 3x to the other side
Sign changes from +3x to -3x
4x-3x-20=3x-3x+15
4x-3x-20=15
x-20=15
Move -20 to the other side
Sign changes from -20 to +20
x-20+20=15+20
x=15+20
Answer: x=35
No, for it to be a right triangle the last length would need to be 2.5 not 3
Answer:
The output is 5
Step-by-step explanation:
-4 is the input (x value). To find the output, you have to find where -4 is on the line. -4 is on the line when 5 is the y coordinate (output).
Based on the way these stations are connected, we can infer that there are <u>56 tubes. </u>
<h3>Number of tubes in Spaceland </h3>
Each pair of stations have 2 tubes. This means that every station is connected to each of the others.
We can therefore infer that each station has 7 tubes to the other stations.
The total number of tubes would therefore be:
= Number of stations x Number of tubes per station
= 8 x 7
= 56 tubes
In conclusion, there are 56 tubes.

Answer:
1.5%.
Step-by-step explanation:
The fractional increase is 15,000,000 / 1,000,000,000
= 15/1000
= 15 * 100 / 1000
= 1.5%
