<span>n = 9 * 27 + 2 * 31 - 28
n = 243 + 62 - 28
n = 305 - 28
n = 277
Firstly do the multiplications and divisions, then additions and substractions.
Hope I could help :)</span>
Answer:
28.5 feet
Step-by-step explanation:
A water tower casts a shadow that is 24 foot long. A 9.5 foot tall tree casts a shadow that is 8 foot long. What is the height of the water tower?
The formula is given as:
Height of the tower/Shadow of the tower = Height of the tree/Shadow of the tree
Let the Height of the tower = x
Hence:
x/24 = 9.5/8
Cross Multiply
8x = 24 × 9.5
x = 24 × 9.5/8
x = 28.5 feet
Therefore, the height of the water tower is 28.5 feet
Answer:
Hint: 0 is x1, -2 is y1, 10 is x2, and -6 is y2.
Step-by-step explanation:
I'm not sure how to explain it, but that's how you can label your coordinates to make it easier to substitute it into the formula. The first number at the beginning of the coordinate is x and the other is y. For example, (3, 7). The three is x and the seven y. If you have two coordinates, then one group has a 1 underneath it while the other has a 2. Simply put, (x1, y1) and (x2, y2). The only thing left is to find the midpoint of segment AB (or line, not sure) by using the midpoint formula.

Answer:
x=1
y=1
Step-by-step explanation:
-3x+4=3x-2
-3x+3x+4=3x+3x-2
4=6x-2
4+2=6x-2+2
6=6x
x=1
y=3(1)-2
y=1
