Help number 5. It would mean a lot.
Answers
This gets pretty easy once you understand how to do these kinds of problems. Let's look at the words in the question.
Adison earned 25$. We can push that to the side.
She loaned her friend 18$, which means she took some money away from her first part of it.
25 - 18 = 7$. Now she has 7$ left. (A calculator would be useful to answer these!)
Now, let's put the 7 to the side and check out the rest of the equation. Looks like Adison's grandmother gave her 50 more dollars, and we know that more means to add.
50 + 7 = 57$.
Now, the final part of the question says she ended up with 86$ because she had money before she earned more. To see how much money she had originally, we can subtract 86 from 57.
86 - 57 = 29$.
We now understand that Adison originally had 29$ before earning anymore money.
Hope this helps!

60 meters = 60 meters * 1km/1000 meters = 0.06 km600 centimeters = 600 cm * 1m/100cm * 1km/1000m = 0.006 km6000 millimeters = 6000mm * 1m/1000mm * 1km/1000m = 0.006km
thus arranging from greatest to least:6km, 60m, 600 cm or 6000mm

The exponent is not the number of years or the number of hours.
The exponent is the number of half-lifes.
In this one, the half-life is 12 hours, and they want to know
how much is left after 36 hours. 36 hours is 3 half-lifes.
The formula that you did is beautiful and almost perfect.
Just change that ugly exponent to the number of half-lifes (3)
and the answer will jump out at you.
F=P(1/2)^(t/h)
F=furure or ending amount
P=present amount
t=time elapsed
h=time the half life is
F=64(1/2)^(36/12)
F=64(1/2)^(3)
F=64(1/8)
F=8 grams

So the question is asking for the time 2 hours and 20 minutes after 7:15.
It's a lot like adding numbers.
So first add the minutes. 15+20 minutes. That would give you 35 minutes.
Then add the hours. 7+2. That would be 9 hours since there is no carry over from the minutes.
The End Time would be 9:35 AM.
Hope this helps :)

in other words, side1+side2>longest side
A. no longest side, so this is possible
B. longest is 17, 14+11>17 so it is possible
C. 414 is longest, 109+214<414 so this is NOT possible
D. 8 is longest, 2+7>8 so it is a possible triangle
E. 26 is longest, 8+15<26 so it is not possible

Answer:
y = √(x - 2) / 2
Step-by-step explanation:
y = 2x^2 + 2.....switch ur x and y and solve for y
x = 2y^2 + 2
x - 2 = 2y^2 ...divide both sides by 2
(x - 2) / 2 = y^2...now take the sqrt of both sides, eliminating the ^2
(√ (x - 2) / 2) = y
