Solve for a.
4/a+4 =-1/a+9
Answer:
a = -8
Step-by-step explanation:
you can solve this proportion by cross-multiplying:
4(a + 9) = -1(a + 4)
now distribute to eliminate parentheses
4a + 36 = -1a - 4
5a + 36 = -4
5a = -40
a = -8

At the organic produce store you can buy 3 bags of sweet potatoes for $20.07.
How much would it cost if you were to buy only 2 bags.
Answer:
$13.38
Step-by-step explanation:
Use proportions to solve this problem:
$20.07 / 3 bags = X / 2 bags
multiply both sides by "2 bags" to isolate the unknown X
$20.07 * 2 / 3 = X
Therefore, X = $13.38
Jamie can paint a wall in 54 minutes Together Connie and Jamie can paint the same wall in 36 minutes How long would it take Connie to paint the same wall by herself
Answer:
The answer is 108
Step-by-step explanation:
I did this for my exam got 100
Together they can paint 5/108 of a wall in 1 minute. So they can paint the entire wall in 108 minutes.
We have given that,
John can paint 1/54 of a wall in 1 minute.
James can paint 1/36 of a wall in 1 minute.
What is the formula for total wall paint in one minute?Total wall paint of both in one minute is calculated by adding the both the paint in one minute it gives us the total paint in one minute
Therefore ,total wall paint in one minute =1/54 + 1/36
So if they work together, they can both paint 1/54 + 1/36 of a wall in 1 minute.
1/54 + 1/36 = 2/108 + 3/108 = 5/108 = 0.04629.
Therefore,together they can paint 5/108 of a wall in 1 minute. So they can paint the entire wall in 108 minutes.

two balls are chosen randomly from an urn containing 5 white, 3 black, and 2 orange balls. suppose that you win $2 for each black ball selected and you lose $1 for each white ball selected. what is the expected amount you will win from this game
Answer:
2.601
Step-by-step explanation:
Given that:
White balls, W = 5
Black balls, B = 3
Orange balls, O = 2
Total = (5 + 3 + 2) = 10
Winning = $2 for each black ball chosen
Winning = - $1 for each white ball
Sample space for making 2 selections ; order does not matter :
{WW, WO, WB, OO, OB, BB}
WW __WO __WB __OO ___OB __BB
-2 ____ - 1 __ 1 ____ 0 ____ 2 ___ 4
WW = 5C2 / 10C2 = 0.2222
WO = (5C1 * 2C1) / 10C2) = 0.222
WB = (5C1 * 3C1) / 10C2) = 0.3333
OO = (2C2) / (10C2) = 0.0222
OB = ((2C1) * (3C1)) / 10C2 = 0.1333
BB = 3C2 / 10C2 = 0.0667
Expected winning = Σx * p(x)
(-2 * 0.222) + (-1 * 0.222) + (1 * 0.333) + (0 * 0.022) + (2 * 0.133) + (4 * 0.667)
= 2.601
The ratio of length to width on a rectangle is
11:3. The perimeter of the figure is 308. what is the
width of the rectangle
Answer:
[tex]Let~the~length~of~rectangle~be~'l'~and~its~width~be~'b'.\\According ~to ~question,\\l:b=11:3\\or, \frac{l}{b} =\frac{11}{3} \\or, l = \frac{11b}{3}\\Also,\\Perimeter~of~the~rectangle=308\\or, 2(l+b)=308\\or, l+b=154\\or, \frac{11 b}{3}+b =154 \\or, \frac{11b+3b}{3} =154\\or, 14b = 154(3)\\or, b=33 units\\So, ~the~width~of~rectangle~is~33units.[/tex]
Alternative method:
[tex]Let~the~length~and~width~of~the~rectangle~be~11x~and~3x.\\Given,\\Perimeter~of~the~rectangle = 308\\or, 2(11x+3x)=308\\or, 14x = 154\\or, x = 11\\Now,\\Width~of~the~rectangle,3x = 3(11)=33 units\\So,~the~width~of~the~rectangle~is~33units.[/tex]

Robin braided g inches of a friendship bracelet. Olivia braided 12 less than 1/3 the number of inches robin braided. Select all of the expressions that represent the total number of inches braided by robin and Olivia
I NEED DONE ASAP PLEASEEE
Answer:
Step-by-step explanation:
The correct expressions that represent the total number of inches braided by robin and Olivia is,
⇒ 4 (1/3g - 3)
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
We have to given that;
Robin braided g inches of a friendship bracelet.
And, Olivia braided 12 less than 1/3 the number of inches robin braided.
Now, The total number of inches braided by Robin and Olivia = Number of inches braided by Robin + Number of inches braided by Olivia
Hence, We get;
⇒ g + 1/3g - 12
⇒ 4/3g - 12
⇒ 4 (1/3g - 3)
Thus, The correct expressions that represent the total number of inches braided by robin and Olivia is,
⇒ 4 (1/3g - 3)
