Answer:
I help!!
Step-by-step explanation:
1. we know that Cara lost 4 less teeth than Kathleen, and the number of teeth Kathleen lost is represented by K. So, any equation that shows K-4=C will do.(feel free to use that equation)
2. this is essentially the same as the first equation, just reversed. So use + instead of -, and instead of ending up with =C you should end up with =K
You are still using the same plugs, C, 4 and K.
3. This is basic math. Cara lost 3 teeth, Kathleen lost 4 more than cara. So, 3+4=?
The correct answer is: [D]: "<span>supplementary angles, 180° " .

Choices:

[B]: "complementary angles, 180° " ; and:
_____________________________________________________
[C]: "supplementary angles, 90° " ;
_____________________________________________________
can automatically be ruled out ; since by definition:
</span>→ Complementary angles always add up to 90° — NOT 180° ;
and: supplementary angles always add up to 180° — NOT 90° .
<span>_____________________________________________________
Note: "Adjacent angles" refer to "supplementary angles" ; which, by definition add up to 180</span>° . Futhermore, looking at the image provided,
we see that ∠1 and ∠2 are, in fact "adjacent" and that ∠1 and ∠2 comprise the entire portion of a "straight line" (being intersected by a transversal)" ;
and as such; ∠1 and ∠2 are supplementary angles—
and as such—add up to 180° .
(which rules out: Choice [A]: "complementary <span>angles, 90°) ;
</span>→ <span>and demonstrates the correct answer:

Answer choice: [D]: "</span><span>supplementary angles, 180°</span><span> " .

Answer:
x
Step-by-step explanation:
factor out both equations and then cancel any of the common factors. You should be left with 4x/4, which simplified is x
