Answer
3.7 or approximately 4 gallons
Step-by-step explanation:
7x2=14 total liters.
3.78 liters=1 gallon
14/3.78= 3.7 gallons
7 mm wide
To solve this, you can use the Pythagorean theorem.
A triangle's sides is length squared + length squared = hypotenuse squared. We know the hypotenuse and one side of the triangle. So, we can follow the equation 24 squared + x squared = 25 squared
To solve this, find the value of 24 squared and 25 squared. 24 squared = 576, and 25 squared = 625, so your equation becomes 576 + x squared = 625
Next, you subtract your known values. 576 + x squared – 576 = 625 – 576 = 49, so x squared = 49
For the last step, find the square root (√) of 49, which is 7. So x = 7 mm
And you can check: 24 squared + 7 squared = 25 squared
Answer:
-3
Step-by-step explanation:
x - 4 = - 7
Carry over the - 4 and make x the subject.
x= - 7 + 4
x= - 3
Therefore x is - 3
Answer:
2
Step-by-step explanation:
First plug in all the numbers into the variables.
3(2^2) - (18 - 4(2))/ 3^2 - 8
This is what your equation should look like after you plugged in 2 for the a and 3 for the b. Then you solve them individually; starting with 3(2^2). 2^2 is 4 and 3 × 4 is 12. So now the equation should look like this:
12 - (18 - 4(2))/ 3^2 - 8
Next, we can solve for (18 - 4(2)). So -4 × 2 is -8, and then you have (18 - 8). That answer would be 10. You should have 12 - 10 on top now, and the answer to that is just 2. Now your equation should look like this:
2/ 3^2 - 8
Now onto 3^2 - 8. 3^2 is 9 because that would just be 3 × 3. Now you have 9 - 8, which is 1. So now you should be left with:
2/1
And that's your final answer.
Answer: There were 20 cars and 10 motorcycle in the garbage.
Step-by-step explanation:
Let x represents the total number of cars and y represents the total number of bikes initially.
Since, Mr. Rich had 2 times more cars than motorcycles in his garage.
Therefore, x = 2y ---------(1)
And, After he bought 1 more car and sold 2 motorcycles, there were 3 times more cars than motorcycles.
Therefore, x+1 = 3(y-3)
⇒x + 1 = 3y - 9
⇒3y - x = 10 ------------(2)
put the value of x from equation (1) to equation (2)
We get, y = 10
Thus again from equation (1), x = 2 × 10 = 20
Therefore,There were 20 cars and 10 motorcycles in the garage.
