You could use a ratio form for the first question
4) 8.5 : 34
29.75 : x x is the unknown
To find x, you must divide 29.75 by the length 8.5 to find the amount needed to be multipled by 34 grams, to find the total grams needed for the length of 29.75
29.75 / 8.5= 3.5 34 x 3.5 = <u>119 grams</u> , which is the answer to 4)
5) Same for this question, use the ratio form
1 1/3 : 3/4 5 / 0.75 ( 3/4) = 6.7
x : 5 miles 6.7 x 1 1/3 = <u>8.91 Miles jack ran</u>
6) ?? (Question not shown)
7) n = 0.6
8) 1 patient : 25 mins
n patients : 7.5 hours
25 mins to hours = 0.4
1 : 0.4
n : 7.5 7.5 /0.4 = 18.75 ----> <u>19 patients</u>
#1) x-8= -12
#2) 15+k= 2
#3) x/-7= -20
#4) (5/8)(x)= -20
The / in #2 means to divide and the ( ) mean to multiply
I see you're probably trying to use a math editor to present this problem. Unfortunately, I'm unsure how to decipher your "-\frac {a }{8.06)." What fraction are you speaking of?
Given "<span>#-\frac { a } { 8.06} + 7.02= 18.4#," all I can say with certainty is that you could legitimately subtract 7.02 from both sides:
</span><span>#-\frac { a } { 8.06} + 7.02= 18.4#
- 7.02 = -7.02
After I've heard back from you, I'll try to help you solve the entire problem.

Answer:
Trevor read 157.5 pages this week.
Step-by-step explanation:
Simple multiplication.
Multiply 5 by 5 first to get 25, carry the 2 on top and then multiply 3 by 5 to get 15, make sure to add 2 to get 17. The first line should be 175.
Put a 0 on the last digit to solve for the next digit. Multiply 4 by 5 to get 20, carry the 2 on top and then multiply 3 by 4 to get 12, make sure to add 2 to get 14. The second line should be 1400.
Add the numbers up to get 1575, since there is one number behind the decimal, you should put a decimal in front of the last 5 for the answer in which it is 157.5.
