The two angles are vertical angles so they are congruent.

3x+18=5x

2x=18

x=9

5x=3x+y
5x-3x=18
2x=18
x=18/2
x=9

3•9+18=27+18=45
5•9=45
Angles have the same measure.

What is (-3 3/4) - (2 1/4)?

lisabon 2012 [21]

Answer: $-6$

Step-by-step explanation:

Rewrite the expression:

$-3\frac{3}{4}-2\frac{1}{4}$

Factor out the negative:

$-3\frac{3}{4}-2\frac{1}{4}$

$-(3\frac{3}{4} +2\frac{1}{4})$

Rewrite the sum:

$-(3\frac{3}{4} +2\frac{1}{4})$

$-((3+2)+(\frac{3}{4}+\frac{1}{4}))$

Calculate the sum:

$-((3+2)+(\frac{3}{4}+\frac{1}{4}))$

$-(5+1)$

Solve:

$-(5+1)$

$-6$
