Answer:
1:25
Step-by-step explanation:
if you divide 575 by 23 you get 25, therefore there are 25 students per 1 teacher
There are 26 letters, four times. There are 10 numbers, four times. 26x26x26x26=456,976
10x10x10x10= 10,000
Final Answer: 4,569,760,000
Answer:
-7x
Step-by-step explanation:
This is actually simpler than you might think. Just subtract.
4x-11x
-7x
() = Fraction
Answer:
1. x=
−(3
/5
y)+
(23
/5)
2. x=−2y+6
Step-by-step explanation:
Let's solve for x.
5x+3y=23
Step 1: Add -3y to both sides.
5x+3y+−3y=23+−3y
5x=−3y+23
Step 2: Divide both sides by 5.
5x
/5
=
−((3y+23)
/5)
x=
−(3
/5
y)+
(23
/5)
------------------------------------------------
Let's solve for x.
2x+4y=12
Step 1: Add -4y to both sides.
2x+4y+−4y=12+−4y
2x=−4y+12
Step 2: Divide both sides by 2.
(2x
/2
)=
−((4y+12)
/2)
x=−2y+6
Hope it helped!
The change in value over 4 years is
$22,000 - 30,000 = -$8,000
so the average change in value per year is
-8000/4 = -2000
