z score = (1300-1700)/75
z score = -400/75 = -5.33
Answer: 5:50
Step-by-step explanation:
20+15+5=40. 6:30 minus 40 min is 5:50
Add <span>6</span> to both sides
<span>2x-6+6=4+6</span>
Simplify <span>4<span>+6</span></span> to <span>10</span>
<span>2x=10</span>
Divide both sides by <span>2</span>
<span>2x/2=10/2</span>
Simplify 10/2
<span><span>x=<span>5</span></span><span>
</span></span>
To find the perimeter of a triangle you simply add up all the sides. Because your possible answers are in fractions, I would convert the decimal values into fractions.
2.2 becomes 2 & 1/5
3.25 becomes 3 &1/4
1 & 5/6 is already a fraction, so you can leave it as it is. To combine these you need to find a common denominator (here it is 60). *It may help to convert the mixed numbers to improper fractions to add them, which is what I did*
You get:
132/60 + 110/60 + 195/60
When you add all that up you get 437/60, which is 7&17/60, so D
I know that was long and wordy, but I hope I helped!!
