<u>Part 1)</u> we have
------> equation A
![x+3y=12](https://tex.z-dn.net/?f=x%2B3y%3D12)
------> equation B
Substitute the equation B in equation A
![5[12-3y]+2y=16](https://tex.z-dn.net/?f=5%5B12-3y%5D%2B2y%3D16)
![60-15y+2y=16](https://tex.z-dn.net/?f=60-15y%2B2y%3D16)
![13y=44](https://tex.z-dn.net/?f=13y%3D44)
![y=44/13=3.38](https://tex.z-dn.net/?f=y%3D44%2F13%3D3.38)
Find the value of x
the best approximation is the point ![(2.3)](https://tex.z-dn.net/?f=%282.3%29)
therefore
<u>the answer Part 1) is the option C</u>
![(2.3)](https://tex.z-dn.net/?f=%282.3%29)
<u>Part 2) </u>we have
------> equation A
------> equation B
equate equation A and equation B
![-x-2=3x+2](https://tex.z-dn.net/?f=-x-2%3D3x%2B2)
![4x=-4](https://tex.z-dn.net/?f=4x%3D-4)
![x=-1](https://tex.z-dn.net/?f=x%3D-1)
Find the value of y
the solution is the point ![(-1,-1)](https://tex.z-dn.net/?f=%28-1%2C-1%29)
therefore
<u>the answer Part 2) is </u>
![(-1,-1)](https://tex.z-dn.net/?f=%28-1%2C-1%29)
Answer:
B- 5 5/6
Step-by-step explanation:
35 divided by 6 is 5 meaning there are 5 whole numbers in the fraction you then figure out how many 6 the remaining amount is which in this case is 5 so the answer is 5 5/6 hope this helps!
Answer: 11
Step-by-step explanation:
30 - 2(7+2)- 1 Distribute or solve parentheses
30 - 14 -4 - 1
30 - 19 = 11
½ × 2 = 1
½ × 3 = 3/2
½ × 4 = 2
½ × 5 = 5/2
Answer:
Every integer is a rational number, since each integer n can be written in the form n/1. For example 5 = 5/1 and thus 5 is a rational number. However, numbers like 1/2, 45454737/2424242, and -3/7 are also rational, since they are fractions whose numerator and denominator are integers.
