Answer:
You need a graph, but x = 3/2 and y = -9/2
Step-by-step explanation:
You need a graph to plot points. Here is a graph:
https://www.wolframalpha.com/input/?i=Plot+the+point+(3%2F2,-9%2F2)
Anyways, 3/2 = 1.5 and -9/2 = -4.5, so that is why it shows those points on the graph.
1.5 is on the x-axis while -4.5 is on the y axis.
Answer:
is this a multiple choice question?
Step-by-step explanation:
You have to multiple 3 times somithing then you just sudtart that to get 18
Answer:
Step-by-step explanation:
you can use hypotenuse formula
45-45-90 isosceles right triangle
so, 45= x
x² + x² = 24²
2x² = 24²
x²= 24.12
x= 
or :
you can use this rule: if you see a 45 45 90 isosceles right triagngle (you can look picture) 45=a cm and 90 = 
cm
so ;
a=
hope this helps ^-^
Answer:
- 18x - 9 = 72
- 3(6x - 3) = 72
- x = 45
Step-by-step explanation:
Apply the distributed property:
- Apply the distributed property: 3/5 × 30x = 18x, 3/5 × 15 = 9
- Re-write the equation: 18x - 9 = 72
- 18x - 9 = 72 is an option listed, so that's one of the answers.
See the other options:
- Another option that looks like it could be the answer is 3(6x - 3) = 72
- Apply the distributed property like we did above, so it now looks like this: 18x - 9 = 72
- This is the same as what we got above, so it is also an answer.
Solve:
- Add 9 to each side, so it now looks like this: 18x = 81
- Divide each side by 18 to cancel out the 18 next to x. It should now look like this: x = 4.5
- x = 45 is an option listed, so that's one of the answers.
I hope this helps!
