The ratio birds : animals = 13 : 2
so for every 1 animal, 6.5 birds were born
last month: animals = birds - 44
birds - animals = 44
use trial and improvement to find:
if there were 52 birds, there must be 8 animals
CHECK: 52 - 8 = 44
Answer:
13x + 16
Step-by-step explanation:
Add the like terms together, like terms are terms that have the same variable or power. Ex. x and 4x are like terms, 4x and 4 are not. x^2 and x^3 are not like terms, x^2 and 2x^2 are like terms.
3+9+5x+4+8x
5x+8x+3+9+4
13x + 16
For Ax+By=C, we have y=-3x. We want both the y and x variable on the same side, and that leads us to either subtract y from both sides or add 3x to both sides. You can do either, but I personally prefer the latter, so we have 3x+y=0. We have A=3 (since that is the coefficient for x) and B=1 (since 1*y=y). Lastly, C=0

Answer:
no
Step-by-step explanation:
In ∆XYZ, we can write the ratios of the sides from shortest to longest as ...
y : z : x = 1 : 1.5 : 2 = 2 : 3 : 4
In ∆QSR, we can write the ratios of the side lengths from shortest to longest as ...
r : s : q = 0.5 : 1 : 1.5 = 1 : 2 : 3
Based on side lengths only, the triangles cannot be similar.
__
<em>Additional note</em>
Even if shortest-to-longest side ratios were the same, the triangle naming is incorrect for them to be similar.
Answer:
Step-by-step explanation:
1. B
(Money coming out of your budget is what you use to buy/pay for stuff, which I'm sure could be categorized as expenses)
2. D (I think. They need to balance their budget in this example so they have the right amount going to each thing)
