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>
Answer: 36π
Step-by-step explanation:
Answer: x = 6
Step-by-step explanation: To solve for <em>x</em>, we must first isolate the term containing <em>x</em> which in this problem is -3x.
Since 28 is being added to -3x, we subtract 28 from both sides of the equation to isolate the -3x. On the left, the +28 and -28 cancel out and on the right 10 - 28 is -18 so we have -3x = -18.
Now we can finish things off by just dividing both sides of the equation by -3. On the left the -3's cancel and we have <em>x</em>. On the right, -18 divided by -3 is 6 so we have x = 6 which is the solution to our equation.
It's the same amount each month, for a year. So:
total money ÷ times money was taken out= how much has been taken out.
