Answer:
x = 70
y = 110
z = 30
Step-by-step explanation:
all triangles add up to 180
30 + 80 = 110
180 - 110 = 70
x = 70
30 + 40 = 70
70 + 80 = 150
180 - 150 = 30
z = 30
40 + 30 = 70
180 - 70 = 110
y = 110
24/16 are both multiples of 8
24/8 = 3 16/8 = 2
3/2
The answer would be -20 because you add and subtract your numbers to get 20
Answer:
Step-by-step explanation:
The first step you want to do is get one variable by itself. We are going to start by isolating y by itself.
-3x + 9y = -27
9y = 3x - 27
y = 1/3x - 3
By isolating y by itself, you now have a function written in slope-intercept form. To graph this function, you can draw a point at (0,-3), then use rise/run to go up 1 unit and over 3 units to the next point (3,-2). You can then draw a line based on this information.
Answer:
Step-by-step explanation:
is essentially 
(you are squaring 
, so multiplying it by itself), so to simplify, you would need to distribute.
A good way to go about this is using the F.O.I.L. method, multiplying the First numbers in the parentheses, then the Outers, then Inners, and finally, Lasts.

After doing so, you would end up with 
, and after combining like terms, 
.
To write the expression in standard form, though, just order the terms from highest to lowest power!
