There are 16 cards in each pile
Step-by-step explanation:
2. 14 3. 110 4. 71 5. 54 6. 16 7. 23
8. 75 9. 32 10. 22 11. 20 12. 48 13. 53
14. Spit 6 in half to get Melinda's length so the answer is 3
15. No the answer is not the same because you have to minus 18 to 8 (which is in the parenthesis) so the answer is 10. But the other way around you have to add 15 (which is in the parenthesis) plus 5.
I really hope I helped you

A runner completed a 26.2-mile marathon in 210 minutes.Estimate the unit rate, in minutes per mile. Round your answer to the nearest tenth of a minute.
Answers
Answer:
The unit rate in minutes per miles be 8.02 minutes per miles .
Step-by-step explanation:
Step 1. 26.2 miles/ 210 mins = x miles / 1min
1 * 26.2 / 210 = .12 miles / min
Step 2. 26.2. 0.13
÷210.
210. 1
(The amount miles ran in 1 minute is 0.13 miles.)
Step 3. 26.2/210= .125 miles per minute
210/26.2= 8.02 minutes per mile
Step 4. 1) Cross multiply. (26.2 = 210x)
2) Divide 210 from each side. (26.2/210 = .1247619048 , 210x/210 = x)
3) Round to the nearest 100th. (.12)
4) X=.12
5) .12 miles ran per minute
Min-jun weighs 191 pounds and plans on losing 4.9 pounds each month. Ahab weighs 216 pounds and plans on losing 6.2 pounds per month. If they stick with their plans, how many months will it take Ahab to weigh the same as Min-jun? Write an equation to represent this situation. Use x as the variable. Find the number of months provide an answer accurate to the nearest month
Answers
Answer:
if i did my math right it should be 216-(6.2*x) 191-(4.9*x)
Step-by-step explanation:
216-(6.2*x) 191-(4.9*x) and if you go up the line from 0 from the first and second equation you will end up at 8 and 5 so Ahab will have to stick to his plans for 8 months/but if it means how much if he needs to reach near or exactly 191 pounds then it would be only 216-(6.2*x) for the equation and the answer would be 4 months

0.2a=48. Solve the equation. Pls, thank you!
Answers
Answer:
a = 240
Step-by-step explanation:
To solve for a, divide 48 by 0.2:
0.2a = 48
a = 48 / 0.2 = 240
Answer:
Simplifying
0.2a = 48
Solving
0.2a = 48
Solving for variable 'a'.
Move all terms containing a to the left, all other terms to the right.
Divide each side by '0.2'.
a = 240
Simplifying
a = 240

Answer:
(x=9)
largest angle= 8x+8(ans=80)
Step-by-step explanation:
first of all we need to find x
we write this as an equation
8x+8+5x-1+5x+11=180
18x+18=180
18x=180-18
18x=162
x=162/18
x=9
Now the question is to find the largest angle
so
we just find the orginal value for all the angles by replacing the x with 9
1. 8x + 8
= 8x9+8
= 80
2. 5x - 1
= 5 x 9 - 1
= 44
3. 5x+11
= 5 x 9 + 11
= 56
Hence the largest angle is 80 ( 8x+8)
Hope this helped.

Answer:
The volume is 259,824,773,000
Step-by-step explanation:
r, or radius is half of the diameter. So we are left with (4 * pi (also known as 3.14159)* 3958.5^3)/3
(7.7947432 * 10 ^ 11) / 3 = 779,474,320,000 / 3
Which is equal to 259,824,773,000 as the volume.
I hope this solves 5 and helps you with 6.

Write an expression having only two terms that is equivalent to 2x – 3. Explain how you wrote the expression and how you can check that it is equivalent.
Answers
Answer:
The expression has a variable with a coefficient (constant) and a constant. Therefore, to create a new expression with 2 terms, take out a constant and use parentheses:
The most obvious number to take out is either 2 or 3 since those are the constants in the expression:
Taking out the constant 3:
[tex]2x-3= 3\left(\dfrac23x-1\right)[/tex]
or taking out the constant 2:
[tex]2x-3= 2\left(x-\dfrac32\right)[/tex]
However, you can choose to take out any value, as long as it's a number and not a variable:
[tex]2x-3= \dfrac12\left(4x-6\right)[/tex]
[tex]2x-3= \dfrac14\left(8x-12\right)[/tex]
To check that it is equivalent, expand the brackets.
3 ((2/3) x - 1).
In order to write it, what is done is that the common factor is taken out three of the expression.
To check which is the same expression, you can multiply three to both terms of the equation:
3 ((2/3) x - 1) = (3 * (2/3) x - 3 * 1) = ((6/3) x - 3) = (2x - 3).
