Answer:
Choice D
Step-by-step explanation:
The distance increases at a steady rate from time = 0 to time = 1.
Then no progress is made between time = 1 and time = 2.
Then the distance increases at the same steady rate from time =2 to time = 3.
Finally, no progress is made between time = 3 and the end of the graph.
Eliminate Choices A, B and C immediately, because none of these scenarios involves a stop and wait.
That leaves only Choice D as a reasonable verbal description of what's happening here.
Answer:
2(x + 1) = 10
x = 4
Step-by-step explanation:
Given:
2(x + 1) = 10
Solution:
Apply Distributive property
A*(B+C) = (A*B) + (A*C)
This means multiply 2 with x and 1
2*(x+1) = (2*x) + (2*1)
2x + 2 = 10
Use Subtraction property of equality
A = B, then A - C = B - C
Subtracting 2 from both sides:
2x + 2 - 2 = 10 - 2
2x = 8 Step 3
Use Division property of equality
It state that if you divide both sides of an equation by same nonzero number then the sides remain equal
Dividing both sides by 2
2x/2 = 8/2
x = 4
This means value of x is 4
Another method to solve this equation is:
2(x+1)=10
Use Distributive property
A*(B+C) = (A*B) + (A*C)
2*(x+1) = (2*x) + (2*1)
2*(x+1) = 2x + 2
Use commutative property
A + (-B) = (-B) + A
2x + 2 + (-2) = 2x + (-2) + 2
2x + 2 + (-2) = 10 + (-2)
2x + 2 - 2 = 10-2
2x = 8
Using division property
AX = B
AX / A = B / A
So
X = B/A
This becomes:
2x = 8
2x = 8.
Divide both sides by 2
2x / 2 = 8 / 2
x = 4

76,543,218. 54,876,547
A way to do it is like this. Numerator divided by denominator so 3 divided by 16 which is .187.
5 divided by 48 is .0146 with the six repeating
