Okay so you’re trying to get them to add up to 540 degrees.
On one side of the equation, have this, and on the other, add up your degrees on the shape.
(3x)+(10x-8)+(5x-12)+(120)+(2x)=540
Start by combining like terms on the left side.
20x+100=540
-100 -100
___________
20x=440
—— ——
20 20
x=22
(On this step, I was just solving and isolating the variable.)
Hope this helps!!
Answer:
D.
Step-by-step explanation:
x = number of glasses of iced tea
y = number of glasses of lemonade
The total number of glasses is
x + y
The total number of glasses is 44
x + y = 44
This is not a choice, but the answer must be equivalent to this equation.
Solve for x by subtracting y from both sides.
x = 44 - y
Answer: D.
32.49y+56.25y
Take 5.7*5.7=32.49
Take 7.5*7.5=56.25
Those are the areas of each square shaped areas in Roberts backyard. Multiply each by then cost of y and then add both together...
6.125
=6.000+0.125
=6+125/1000
=6+1/8
With the f(x) = x^2 - 2x + 1 there is an even degree polynomial as the highest degree here is 2 and there is a positive leading coefficient as the coefficient for the highest degree is considered to be 1. Therefore all statements for f(x) is false.
With g(x) = x^3 +1 there is an odd degree polynomial as x is raised to 3 and there is a positive leading coefficient as x^3 is multiplied to 1. Therefore only the fourth statement holds to be true
