Answer:
x= -4/5
Step-by-step explanation:
first distribute on both sides
8x -8 = -2x -16
isolate x on one side
10x = -8
x = -8/10
you can simplify that fraction to get
x= -4/5
Answer:
32, 40, 48, 56
Step-by-step explanation:

Answer:
x = 16 y = 22.627 (or 16
)
Step-by-step explanation:
cos(45) = 16/y
y = 16/cos(45)
y = 22.627
tan(45) = 16/x
x = 16/tan(45)
x = 16
*this can also be found because we know this is a right triangle with two angles of 45 degrees. This means that both sides will be equal so x will be 16 and the diagonal will be 16 root 2 (22.627)
4y + 3y = 7y
The answer is 7y. Because of the arithmetic rules, bracket should be taken first, then multiplication.
B = bracket
o = of
D = division
M = multiplication
A = addition
S = subtraction
3x-4=-31
+4 +4
3x=27
X=9
Hope this helps
