Answer:
1. The like terms are 5x^2 and 4x^2
4x^5 + 4y^4 + 9x^2 +4
2.-5v^3 + 2v^6 - 3
3. 15u^2 v + 12uv + 5
5. My day was great! I recommend call me by your name, little women, all the brightest places, ratatouille, original Marry Poppins, John Mulaney, about time, someone great, irreplaceable you, one day, clueless, and the spectacular now!
Step-by-step explanation:
5x+y=2
4x+y=4
5x+y=2
-1( 4x+y=2)
5x+y=2
-4x-y=2
your y'all cancel out so you r left with
x=-2
then you plug the x in to one of the equations
5(-2)+y=2
-10+y=2
then add 10 to both sides
y=12
Answer: x = -2 y = 12
there's the work and all its simple you just have to figure out how to get rid of y or x ( which ever is easier) and you can figure it out after that
Answer:
omigosh hope she gets better i will look at the pdf and solve
Step-by-step explanation:
okay so for most of them you can just multiply by the denominator to turn it into a regular number (to get it out of fraction form) and then use basic algebra to solve for x. I 'll write the answers to problems 1-9 in the comments
The answer is
8(8.8 x 10^12) = <span>70.4 x 10^12
the answer is </span><span>A. 70.4 x 10^12</span>
Here we have one large triangle with two smaller triangles drawn inside. The two smaller triangles are similar.
Thus, a/12 = 12/16, or a/12 = 3/4, or 4a=36, or a = 9.
Find b in the same way: b/20 = 9/12 (and so on).
