Answer:
a=8
c=5.5
Step-by-step explanation:
solve simultaneously:
2a + 4c = 38.00
3a + 3c = 40.50
times the first eq. by 3 and the second by 2
6a + 12c = 114
6a +6c = 81
subtract from one another
6a + 12c = 114
-6a +6c = 81
6c = 33
c=5.5
3a + 3x5.5 = 40.50
3a= 24
a=8
Answer:
The 3 angles are 62 2/3, 44 2/.3 and 72 2/3 degrees.
Step-by-step explanation:
let x be the first angle then the the second angle is x - 18 and the third angle = x + 10
The 3 angles add up to 180 so:
x + x - 18 + x + 10 = 180
3x = 180 + 18 - 10 = 188
x = 188/3 = 62 2/3 degrees.
x - 18 = 44 2/3
x + 10 = 72 2/3.
Answer:
2 Superscript 4 x Baseline = 2 Superscript 3 x minus 9
8^(x-3) = 2^(3x-9)
Step-by-step explanation:
2⁴ × 8^(x - 3)
2⁴ × (2³)^(x-3)
2⁴ × 2^(3x - 9)
Since the bases are same now, powers can be added
2^(4 + 3x - 9)
2^(3x - 5)
