Answer:
11/15 km
Step-by-step explanation:
Simply sum the areas:
2/5 + 1/3 = (6 + 5)/15 = 11/15
Answer:
Step-by-step explanation:
Length of:
First piece = x
Second piece = 4x
Third piece = 5x
Equation: 30 = 4x + 5x + x
Solving the Equation:
10x = 30
x = 3
Lengths of:
First piece = 3 inches
Second piece = 12 inches
Third piece = 15 inches
Answer:
X=2
Step-by-step explanation:
Ratios
4:x = 24:12
24:12 reduced is 2:1
Therefore we can see x must be half of 4.
So the answer is 2
Hope this helps! :)
pls mark brainiest
The volume of a cube = length x width x height. Since they told us this box has a square base, the length and width are both 18 inches.
V = 18 x 18 x 16
V = 5184 cubic inches or in^3
The formula is (2)(n-4) = n-1/4
Mult both sides by 4:
8n - 32 = 4n -1, or 4n = 31, or n=31/4.
If this is not what you expected, please ensure that you have copied down the original problem correctly. What do you mean by "1/4 less?"
Let's try (2)(n-4) = 1n-(1/4)n = (3/4)n. Then,
2n-8 = (3/4)n, or (5/4)n = 8. Mult. both sides by (4/5), we get:
n = (5/4)(8) = 10. Is that what you were hoping for?
