Combine like terms: 4+7x=11
subtract 4 on both sides: 7x=7
divide by 7 on both sides: x=1
Answer:
7
Step-by-step explanation:
n= 4, a= -5, d = -1-(-5)= -1+5 = 4
Tn = a + (n-1)d
Tn = -5 + (4-1)4 = -5 + (3)4 = -5+12 = 7
Answer:
2400*8*.045= 864+2400=3264
Step-by-step explanation:
Your work appears to be correct.
The results from a graphing calculator are in agreement.
Let's take this number:
<h2>
28/7</h2>
WHY this number fits the criteria?
- It's an improper fraction since the numerator is higher than the denominator
- It's value IS between 1-5 because 28 divided by 7 = 4, 4 is in middle of 1-4
- The denominator IS 7
How did I find this number?
- I did 7x4 to get the numerator, so that it would be between 1-5
- And I made sure that it's an improper fraction
- And also, I made sure that the denominator is 7
<h2>
Hence, 28/7 can be one answer</h2>
