13 x 17n - 13 x 15
= 221n - 195
For this case we have the following conversion:
20 pounds = 9 kilograms
To use the table what we must do is find another relationship that allows us to find the weight in kilograms for 30 pounds.
For example, half the weight in pounds is half the weight in kilograms.
Therefore, the given conversion is:
10 pounds = 4.5 kilograms
So, for 30 pounds, we multiply this last ratio obtained by three on both sides:
30 pounds = 13.5 kilograms
Then, the table is:
Pounds 10 20 30
kilograms
4.5 9 13.5
Answer:
Using the ratio table the dogs weight is:
30 pounds = 13.5 kilograms
Answer:
290 in²
Step-by-step explanation:
The surface area of a prism is found using the following formula: SA = 2(lh+lb+bh). This formula takes the area of each face (6 in total( and adds them together to find a total sum. Substitute l = 3, b = 8 and h = 11 to solve for the surface area.
SA = 2(lh+lb+bh)
SA = 2(3*11+3*8+8*11)
SA = 2(33 + 24 + 88)
SA = 2(145)
SA = 290

So the first thing we need to do is set up an equation (using x to represent the number). Then, we'll solve it to get the answer.
Step 1: Translate the word problem into an equation
Word problem: The sum of nine and six-tenths and a number is thirteen and two-tenths.
Equation: + x =
Step 2: Isolate x by subtracting from each side
+ x - = -
Step 3: The numbers on the left cancel out, leaving x alone
x =
Step 4: Convert the answer to decimals
x = 3.6
