Answer:
The answer to your question is: x = 1/2
Step-by-step explanation:
5^(2x + 1) = 25
Find the prime factors of 25
25 5
5 5
1
Then 25 = 5²
The equation can be expressed as:
5^(2x + 1) = 5^2
As the base is the same (5), eliminate it.
2x + 1 = 2 Solve for x
2x = 2 -1
2x = 1
x = 1/2 Result
area = (l)(w)(h)
24 = 4(3 + b)
24 = 12 + 4b
-12 on both sides
12 = 4b
/4 on both sides
b = 3 inches
Substitute b = 3 inches in width
3 + b
3 + 3 = 6 inches
Answer:
width = 6 inches
Answer:
for brand a= $8 per/kg and brand b=$5 per/kg
Step-by-step explanation:
Let A be the cost per kg. of brand a
Let B be the cost per kg. of brand b
forming the equation: (wt. * cost + wt. * cost = wt. * cost)
4A + 6B = 10(6.20)
------(1)
2A + 8B = 10(5.60)
------(2)
lets find out the values of A and B by solving above equations.
(1)=>
put this value in eq(2)
(2)=>
= 5 ---> ($5 per/kg for B)
now for A,
=8 ---> ($8 per/kg for A)
Answer:
The answer is 25
