Step-by-step explanation:
1. 5+2+3=5+(2+3) 2. 9a is equivalent to 11a-2a 3. 7a + 04 - 2a is equivalent to 7a + -2a + 4 4. 8a-(8a-8) is equivalent or = to 8.
Answer:124
Step-by-step explanation:
2x + 8 + x - 2 = 180
Add like terms
3x + 6 = 180
Subtract the 6 from both sides
3x + 6 - 6 = 180 - 6
3x = 174
Divide by 3
x = 58
Now we have to find the measure of angle ACD
2(58) + 8 = 124
She put nine muffins on each plate. 9 x 4 is 36.
Answer:
57.04
Step-by-step explanation:
2 x 1.2 = 2.4
2.4 x 2.4 = 5.76
5.76 + 9 = 14.76
14.76 x 2 = 29.52
5.76 + 8 = 13.76
13.76 x 2 = 27.52
29.52 + 27.52 = 57.04
