<span>Randall’s family drove to the beach for vacation. Assume they drove the same speed throughout the trip. The first day, they drove 130miles in 22 hours. The second day, they drove 325 miles in 55 hours. The third day, they arrived at the beach by driving 390 miles in 66 hours.</span>
Answer:
e < 2
Step-by-step explanation:
Given
e - 2 < 0 ( ad 2 to both sides )
e < 2
Answer:
I <em>believe</em> the answers are= 2, 3, 6, 8
Step-by-step explanation:
For #2, you would subtract 2 from both sides. 10-2=8. x=8.
For #3, you would add 4 to both sides of the equation, making the final answer: x=8
For #6, you would divide both sides by 3. 24 divided by three is 8.
For #8, I multiplied the whole equation by 8, which is the denominator of x/8. 1 times 8=8. The final answer would be x=8.
Hope this helps!

</span><span><span>The General rule for adding and subtracting numbers </span><span>
1. Two integers with the same signs
Once 2 integers has the same sign, then just add the numbers.
For example</span>
<span>1. 1+1 = 2 </span>
<span>2. 2 + 5 = 7 </span><span>
2. Two integers with different signs
<span>When 2 integers has different sign, then find the difference
For example
1. 1-1 =0</span></span>
<span>2. 2 – 5 = -3 </span><span>
3. Two integers that vary in sign
<span>When 2 integers vary in sign, then it will depend who which number carries the largest value
For example</span></span> <span><span>
1. </span>-3 + 2 = -1</span>
<span><span>2. </span>2 – 1 = 1</span><span> </span></span>
