Answer:
A
Step-by-step explanation:
When the temperature has a negativ sign on it, it is below zero
When the temperature is a natural number, it is above zero
Greater than means it can only be greater than the value give for example x is greater than 10, x can only be a number greater than 10. Greater than or equal to is similar because the answer can be greater than the value given or equal to it. For example x is greater than 10, x could be equal to 10 or any value greater than it.
Answer:
x = 2
y = -3
z = 4
( 2 , -3, 4 )
Step-by-step explanation:
x + y + z = 3 ---- i
x – y =5 ---- ii
y - z = -7 ---- iii
ii + iii
x - z = -2 ---- iv
i + ii
2x + z = 8 --- v
iv + v
3x = 6
x = 2
x=2 substitute for v
z = 4
x =2 substitute for ii
y = -3
Answer:
Area is 24
Step-by-step explanation:
The three sides of the triangle are 6, 8, and 10. You could use A² + B² = C² and determine that A² + 36 = 100 to find the missing side is 8.
Then, the area of the square is 6 × 8 = 48. And each triangle that makes up the square is 48 ÷ 2 = 24.
