Answer:
x = 11
Step-by-step explanation:
∠BCE + ∠ECF = 180°
∴(10x + 15)° + 5x° = 180°
(15x + 15)° = 180°
15x = 180° - 15°
15x = 165°
x = 165°/15°
x = 11°
Answer:

Step-by-step explanation:
Art bought
and
yards of fabric.
Total fabric bought: 
To add both fractions, we convert them into improper fractions (multiply denominator with whole number, then add the numerator) and then we find the LCM of the two denominators: 12 and 16
LCM of 12 and 16 = 48

We reduce this fraction to mixed fraction (or reduce if possible), since 1027 and 48 have no common factors.

Answer:
x = 1.5; 20x + 5 = 35; 24x + 1 = 37;
Step-by-step explanation:
______________________________
1) 20x + 5 = 24x - 1
2) 20x + 6 = 24x
3) 6 = 4x
4) x = 1.5
_______________________________
20x + 5
1) 20(1.5) + 5
2) 30 + 5
3) 35
_______________________________
24x + 1
1) 24(1.5) + 1
2) 36 + 1
