Hence, the equation for the question (7) is 
and equation for (8) is 
. It can be solved by linear equation in one variable.
What is a linear equation in one variable?
A linear equation in one variable is written as 
. Here, 
and 
are constants and 
is a variable.
(7)
Consider n number of baseball cards does Mike have. Since this is 19 less then the cards Allan have hence, as you add 19 in n then it will give 84.
(8)
Consider the speed of Michelle is n. As, it is 3 times less than the speed of the Jamie hence, it you multiply 3 with n then it will give 12.
Hence, the equation for the question (7) is and equation for (8) is .

Since 34 only goes into 7 four times the answer is 28 with a remainder of 6:) so basically you would could by your 7s so 7, 14, 21, 28, 35 and since 35 is too much we would have to go with 28. so then we subtract 28 from 34 and that gives us 6 left over. hoped this helped:))

Answer:
P(4.7≤x≤5.3)≈0.6827≈68.27%
Step-by-step explanation:
Notice that 4.7 is 1 standard deviation below the mean (μ) and 5.3 is 1 standard deviation above the mean. Thus, by the Empirical Rule, ±1σ represents about 68.27% of the data in a normal distribution, meaning that P(4.7≤x≤5.3)≈0.6827
