Answer:
a = -8
Step-by-step explanation:
4/a + 4 = -1/a + 9
-1(a + 4) = 4(a + 9)
-1a - 4 = 4a + 36
-5a - 4 = 36
-5a = 40
a = -8
Answer:
Katie is 6 years old and Thomas is 3 years old
Step-by-step explanation:
Given that we should let K and T be the current ages of two siblings, Katie and Thomas.
If Katie is currently twice the age of Thomas then,
K = 2T
and in 6 years, Katie will be 4 times Thomas's current age then
K + 6 = 4T
Solving both equations simultaneously by substituting the value of K given in the first equation into the second
2T + 6 = 4T
Collect like terms
6 = 4T - 2T
6 = 2T
Divide both sides by 2
T = 3
Recall that K = 2T
K = 2 * 3
= 6
Hence Katie is 6 years old while Thomas is 3 years old
Answer:
See below
Step-by-step explanation:
If by circumference you meant perimeter and diameter you mean length, then here is my answer.
Perimeter = 2L+ 2W
13653= 2*L + 2*5431
13653= 2L + 10862 Subtract 10862 from both sides
2791= 2L Divide by 2
L= 1395.5
The diameter is 1395.5
Answer:
2
Step-by-step explanation:
24/ 11 = 2 2/11
so, we have 2 and 2/11
11x2 = 22 + 2 = 24
