Error! Because that does not make any sense
Answer:
<em>x = 10</em>
Step-by-step explanation:
These angles are <em>same side interior angles</em>.
This means that (11x + 10) + (10x - 40) = 180
Solve for x:
11x + 10 + 10x - 40 = 180
21x - 30 = 180
+30 +30
21x = 210
/21 /21
<em>x = 10</em>
Answer:
288
Step-by-step explanation:
76+45=121
121+98=219
219+76=295
295-7=288
A: Deena subtracted 25, instead of adding it.
B: 9x - 25 = 88.
C: no idea
Answer:
4
Step-by-step explanation:
If x is the third number, then x−1 and x−2 are the second and first numbers.
10(x−2) + 10(x−1) = 10 + 10x
x − 2 + x − 1 = 1 + x
2x − 3 = 1 + x
x = 4
