Answer:
the answer is a because the 3 is a whole number and whole numbers are bigger than fractions and the thing next to the whole number is a fraction so its a

Answer:
For solving x x= -24+y/4 For solving Y y=−24−4x
Step-by-step explanation:
This is solving for x
Add y to both sides.
−4x=24+y
Divide both sides by -4
and the answer is
x= -24+y/4
THis is solving Y
Add 4x to both sides
−y=24+4x
Multiply both sides by -1
and the answer is
y=−24−4x
Rancho middle school has an average of 23 3/8 students per teacher.write this mixed number as a decimal.
Answer:
![23\frac{3}{8} = 23.375](https://tex.z-dn.net/?f=23%5Cfrac%7B3%7D%7B8%7D%20%3D%2023.375)
Step-by-step explanation:
Given:
The given mixed number is ![23\frac{3}{8}](https://tex.z-dn.net/?f=23%5Cfrac%7B3%7D%7B8%7D)
We need to write the given mixed number as a decimal.
So, we find the decimal number by separating the parts.
![=23+\frac{3}{8}](https://tex.z-dn.net/?f=%3D23%2B%5Cfrac%7B3%7D%7B8%7D)
The value of ![\frac{3}{8}=0.375](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B8%7D%3D0.375)
![=23+0.375](https://tex.z-dn.net/?f=%3D23%2B0.375)
![=23.375](https://tex.z-dn.net/?f=%3D23.375)
Therefore, the decimal number of given mixed number is ![=23.375](https://tex.z-dn.net/?f=%3D23.375)
Answer:
C. (2, 5)
Step-by-step explanation:
Looking at the answer choices, you can see that solving for y will tell you which choice is correct. We can eliminate x from the equations by adding 4 times the second equation to the first:
(8x -3y) +4(-2x +3y) = (1) +4(11) . . . . . adding the equations to eliminate x
9y = 45 . . . simplified; next we divide by 9
y = 5 . . . . . matches choice C
