A girl's feet are negative 2 over 4 yards from the surface of a pool. A boy's feet are negative 3 over 4 yards from the surface of the pool. Determine whose feet are closer to the surface.
The girl's feet are closer to the surface of the pool because negative 2 over 4 > negative 3 over 4.
The boy's feet are closer to the surface of the pool because negative 2 over 4 > negative 3 over 4.
The girl's feet are closer to the surface of the pool because negative 2 over 4 < negative 3 over 4.
The boy's feet are closer to the surface of the pool because negative 2 over 4 < negative 3 over 4.

Barb purchased a loaf of bread for $2 and p pounds of sliced gam at $5 per pound for a total of 13.25. The relationship between what she purchased and her total purchase price is represented by the equation 5p + 2 = 13.25. What was the total number of pounds of ham that Barb purchased?
Please help with this! I was having problems with the answer and I just wanted to know if I was right.
Answer:
108 degrees
Step-by-step explanation:
By the Exterior Angle Theorem:
(2x + 1) + 63 = 5x -2
2x + 64 = 5x - 2
66 = 3x
22 = x
Now, we can plug the value of x back into the expression that represents the exterior angle to find the measure of the exterior angle:
5(22) - 2
110 - 2
108
The answer is 108 degrees. (I'm sorry your question was answered so late; I hope you got the right answer when you solved it!)

I'm kind of skeptical because none of them seem right to me, but X would be the one that makes more sense.
Y=4x +5 y=x -4 a (3, 17) b (-3, -7) c (-3, 7) d (3, 7)
Answer:
(-3, -7)
Step-by-step explanation:
y = 4x + 5
y = x - 4
add 4 to both sides of the second equation to get y + 4 = x
plug that back into the equation to get y = 4(y + 4) +5
distribute to get y = 4y + 16 + 5
combine like terms y = 4y + 21
subtract 4y on both sides to get -3y = 21
divide both sides by -3 to get y = -7
plug -7 into the second equation to get -7 = x - 4
add 4 on both sides to get -3 = x
therefore (-3, -7)

Measurements of atoms, such as amounts, distances, and weights, are often very large or very small when compared to measurements of things you can see or touch. Scientific notation represents numbers as a power of 10. This makes very large or small numbers easier to use and understand. Approximately 7,500,000,000,000 carbon atoms fit across the period that you make with your pencil. Express this number in scientific notation. (PLEASE ANSWER FAST I'LL GIVE BRAINLIEST ALSO PLEASE DO ALL THIS IS WORTH 30 POINTS)
Step 1 Rewrite the number with a decimal after the first nonzero digit.7.500000000000
Step 2 Find the number of places and the direction you moved the decimal. If a number does not show a decimal, the decimal is at the right end of the number.You moved the decimal 12 places to the left.
Step 3 Drop the zeros, and write the number of places you moved the decimal as a power of 10. If you moved the decimal to the right, the power is negative. If you moved the decimal to the left, the power is positive.7.5 × 10 12
Step 4 Reverse the process to change scientific notation back to a whole number. A positive power of 10 moves the decimal to the right. A negative power of 10 moves the decimal to the left.

Answer:
x is 23
Step-by-step explanation:
cause it is an 180 angle so 180-93=87
87 -18 =69
3x=69
x=23
Answer:
x=23Step-by-step explanation:
in order to find x
(3x+18)° + 93°=180°
⇒3x+18=180-93
⇒3x=180-93-18
x=69/3
x=23
and there we go X = 23
hope it helps :)

Clare bought a bag of 84 sour candies. She ate s of the candies. Write an expression that shows how many sour candies Clare has now.
Type an asterisk ( * ) if you want to use a multiplication sign and a slash ( / ) if you want to use a division sign.
Divide. 0.78÷106
0.00078
0.000078
0.0000078
0.00000078
Answer:
Answer: A.
Step-by-step explanation:
I did the test and got it correct.
Answer:
the answer is not A. the correct answer is D. 0.00000078
Step-by-step explanation:
The reason D.
is correct is because if you multiply 10 six times you will get 1,000,000
and all you have to do is take the zeros from 1,000,000 and add it to 0.78 you will get your answer.
(hope this helps)
