This is hard I’m not sure
Multiply 6 by numbers 1 -6:
To get:
6, 12, 18, 24, 30,36
She cover more distance after rest 101.7-88.4625=13.2375
6.2, 7.0
To find the common difference between two outputs you will subtract the current output number from the proceeding number. Ex 5.4 - 4.6 = 0.8 and 4.6 - 3.8 = 0.8. Because they are the same value it means the function increases at a rate of 0.8 for each input of a.
so 5.4 + 0.8 = 6.2
and 6.2 +0.8 = 7.0.
8x+15=7
In the statement the phrase the sum of can tell you that it is going to be an addition problem. So 8x ( eight times a number) would be added to the 15, 8x+15. Since its an addition problem the part where it says ' ... is seven', you know that it will all equal 7. So the answer would be 8x+15=7.
