Answer:
x = -2
Step-by-step explanation:
Step 1: Subtract 7 from both sides.
3x+7−7=1−7
3x=−6
Step 2: Divide both sides by 3.
3x/3 = −6/3
x = −2
L = 2.2 cm
And the formula of length for a square is L^2, then the answer is 2.2^2
Or 4.84
Answer:
the awnser is 143X.
Step-by-step explanation:
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.
Answer:
480 in^3
Step-by-step explanation:
Multiplying the length of each of the sides together gives the volume, so
