Answer:
Step-by-step explanation:
Increased amount = 3 - 2.50 = $ 0.50
Increase percentage = 
= 5 *4
= 20%
Answer:
Step-by-step explanation:
P = 2(l +w)
Let width be x
Length = x + 13
P = 38
38 = 2(x + 13 + x)
38 = 2(2x + 13)
38 = 2x + 26
2x = 38 - 26
2x = 12
x = 12/2
x = 6unit
Width = 6units
Length = x + 13 = 6+13 = 19units
Step-by-step explanation:
Given
If x = 4 Then
3x + 1 = 3 * 4 +1 = 12 + 1 = 13
The answer should be 13.
Answer:
v= 1/6
Step-by-step explanation:
1. Simiplify 10/3v = 10/3v -5/9= -10v/3
2. Multiply both sides by 3
3. Use this rule : a/b × c = ac/b
4. 5× 3= 15 -15/9= -10v
5. Simiplify 15/9 = 5/3 -5/3 = -10v
6. Divide both side by -10 -5/3/-10=v
7. Two negative make a postive 5/3/10 = v
8. Simplify 5/3/10= 5/3×10
9. Simplify 3×10=30 5/30=v
10. Simplify 5/30 = 1/6v
11. Swith sides v= 1/6
wouldn't it be 6+8 I think that that's what it means by algebraic equation. Hope I could help.
