Answer:
2
Step-by-step explanation:
<em>Add 1.5 to both sides:</em>
5/2x-1.5+1.5=3.5+1.5
5/2x=5
<em>Multiply both sides by 2/5</em>
(2/5)*(5/2x)=(2/5)*(5)
Answer: First you need to calm down my man. a. 12. b 15 c. 9
2 1/2 hours
2 9/12 + 2 2/12 (3rd option)
Marsh trail is 2 5/10 or 2 1/2 miles longer than Woodland Trail
Step-by-step explanation: Question 3. a. Common Denominator is 12 b. Common Denominator is 15 c. Common denominator is 9. Question 4 It will take 2 and 1/2 hours to complete all of his tasks. Question 5. 2 9/12 + 2 2/12 Question 2. Marsh Trail is 2 5/10 and 2 1/2 miles longer than Woodland Trail. Hope this helps and stay calm.
X=1+9
X=10
Here is you answer
3. Divide by 5
4. Add 12
5. Multiplying by -8
6.subtracting by -6
Answer:
First, you have to form simultaneous equation for both of their ages in yerms of a and b :
b = 4a - 12 -------- ( 1 )
a + b = 28 -------- ( 2 )
Next, you will have to solve it by substituting ( 1 ) into ( 2 ) :
a + (4a - 12) = 28
5a - 12 = 28
5a = 28 + 12
5a = 40
a = 8
Then, substitute a = 8 into ( 1 ) :
b = 4(8) - 12
b = 32 - 12
b = 20
