Think of absolute value and inverse operation, +72 to 72 and 24
A = b*h*0.5
24 = 4*0.5*h
24 = 2*h
h = 12
Height is 12 inches.
It sounds like they had $708.88 at the beginning, however by the end of the year they OWED $347.99. The first number is in the positive while the other is a negative. Add the last number to the first number for the amount that they have spent which would be $1,056.87.
Answer:
Step-by-step explanation:
Since the ratio is 4x:4x:7x, if we add all those numbers up we get 15. Then we do 75/15 to get what x equals. So we get 5. So x equals 5. Following the rules of multiplication, you do 4(5):4(5):7(5), and simplifying that further, you get 20:20:35. If we add all those values up, we should get 75, and we do!
If you're wondering why I did 4x:4x:7x instead of 4:4:7, it's because a ratio is just a...well ratio? It's easier to visualize if you put a variable because the variable could be anything, and you would have to multiply all the given values to get the same proportions. In summery, I did it so it was easier to visualize
A midsegment is half as long as the one it's parallel to.
2. x = 16/2 = 8
3. y+4 = 6
y = 2
4. z/2 = 15/2
z = 15
5. (5/2)x + 4 = (6x +4)/2
2 = x/2
x = 4 . . . . . . matches selection b.
