Answer:
12.42 + 3.6 = 16.02
1.81 + 19.25 = 21.06
-3.5 + 85.95 = 82.45
-75.23 + (-21.8) = -97.03
123.49 + (-6.02) = 117.47
Hope this helps.
C = 3.14 x D or C = 2 x 3.14 x R
So, C = 2 x 3.14 x 20
The answer is 40pi.
40% is the answer for the quantity of percentage
Answer:
simplified value of the exponential expression 27 Superscript one-third
27= 3×3×3
=
answer is 3
Step-by-step explanation:
1. Cross multiply
35x = 5(11)
35x = 55
Divide both sides by 35
x = 55/35
x = 11/7
2. (x - 2)/x = 3/8
Cross multiply
3x = 8(x - 2)
3x = 8x - 16
Subtract 8x from both sides
-5x = -16
divide both sides by -5
x = -16/-5
x = 16/5 OR 3 1/5
3. (a + 1)/(a - 1) = 5/6
cross multiply
6(a + 1) = 5(a - 1)
distribute
6a + 6 = 5a - 5
subtract 5a from both sides
a + 6 = -5
subtract 6 from both sides
a = -11
4. (1/3)x - 4 = (2/3)x + 6
multiply each term by 3 to clear the fractions
x - 12 = 2x + 18
subtract x from both sides
-12 = x + 18
subtract 18 from both sides
-30 = x
