Answer:
Step-by-step explanation:
First add 5x to 12x which becomes 17x and subtract 8 from 12 which becomes 4. So the answer is 17x+4!
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>
The “if” portion is called the hypothesis, just like in a scientific experiment.
Answer:
Step-by-step explanation:
f(x) = √16x
f(x) = 3/8 √9x
f(x) = 6/5 √x
Answer:
1,400,000,000
Step-by-step explanation:
Since there are 7 billion people on the earth, you must divide 7,000,000,000 by 5 and you arrive at the answer of 1,400,000,000.
Hope that helps!
