70 kilometers because you have to multiply 3.5 by 20.
Increasing. It helps to graph it out.
Answer:
bottom right, x = 90
bottom left, x = 40
top left, x = 28
Step-by-step explanation:
This problem uses the variable x to mean three different numbers.
This is an incorrect use of a variable.
On the bottom right, x is a right angle, so x = 90.
On the bottom left, x + 5 = 45, so x = 40.
On the top left, 3x + 6 = 90, so x = 28.
Ugh this hurts my head just looking at it, but I'll show the process.
PEMDAS
Addition before subtraction (Not that it matters here).
2 - (-4) is the same as adding 4. This equals 6.
-1 - (-3) is the same as adding 3. This equals 2.
Adding these two expressions together equals 8.
Showing my work...
2 - (-4) + (-1) - (-3)
6 + (-1) - (-3)
6 + 2
8
