D is the answer to your question
Answer:
x = -2
Step-by-step explanation:
The given equation is a multi-step equation since it has the variable on both sides of the equal sign. However, the goal of any equation is to isolate the variable (get it by itself) by using inverse (opposite) operations to get the variable on one side of the equal sign and the numbers on the other.
5x - 5 = 3x - 9
1. Subtract '3x' from both sides:
5x - 3x - 5 = 3x - 3x - 9
2x - 5 = -9
2. Add '5' to both sides:
2x - 5 + 5 = -9 + 5
2x = -4
3. Divide '2' from both sides:
2x/2 = -4/2
x = -2
The answer is 30 degrees option b
Answer:
Step-by-step explanation:
Given that acceleration of an object is
is the solution to the differential equation
Since v(0) =7
we get ln 7 = C
Hence
since velocity is rate of change of distance s we have
substitute t=0 and s=0
So solution for distance is
Answer:
D
Step-by-step explanation:
For this type of problem, we need to think of it as a ratio.
The first tree to shadow ratio would be 40:12 this can be simplified to 20:6 which can be simplified to 10:3.
The second ratio is 5:x. I say x because it's an unknown number. Since 5 is half of ten, then the x would be half of three. Therefore the answer is D.
