Solve five ninths plus four sixths
sixty six fifty fourths
ten fifteenths
nine tenths
thirty ninths
Answer:
Your answer will be Sixty Six Fifty Fourths
Step-by-step explanation:
Make it the same denominator so you can add them (18.)
Multiply 5/9 by 2 and multiply 4/6 by 3.
10/18 + 12/18 = 22/18.
Since there is not 22/18 listed, you can use this fraction as a proportion. The only proportion that can be evident is answer A, as when you multiply 22/18 by 3, you get 66/54.
Hope this helps! ;)

Select the statement that describes this expression: 13 + fraction 1 over 2 x (6 ÷ 2 + 6) A: 13 more than half of 6 more than the quotient 6 and 2 B: 13 more than half of the quotient of 6 and 6 minus 2 C:Half of 13 multiplied by the quotient of 6 and 2 plus 3 D:13 plus half of 6 divided by 2, then subtract 6
Answer:
"13 plus half of 6 divided by 2, then add 6"
Step-by-step explanation:
We need to select the statement that describes this expression :
[tex]13+\dfrac{1}{2}\times (\dfrac{6}{2}+6)[/tex]
Here 13 is added to half of 6 divided by 2 and then add 6.
Hence, this is the correct answer "13 plus half of 6 divided by 2, then add 6).

Solve the equation for a.
K = 4a + 9ab
a = K(4 + 9b)
a = 4(K + 9b)
a = a equals StartFraction 4 plus 9 b Over K EndFraction equals h.
a = a equals StartFraction K Over 4 plus 9 b EndFraction equals h.
Answer:
[tex]a= \frac{k}{9b+4}[/tex]
Step-by-step explanation:
In this question, you would solve for "a".
Solve:
K = 4a + 9ab
Since we have our "a" on the same side, we can factor it out from the variables:
K = a(9b + 4)
To get "a" by itself, we would have to divide both sides by 9b + 4:
K/9b+ 4 = a
Your answer would be K/9b+ 4 = a
It would look like this: [tex]a= \frac{k}{9b+4}[/tex]
Answer:
it's a = K / 4 + 9b

Answer:
4. $648
5. $86.40
Step-by-step explanation:
You take the percent (we'll take 4 for example, so 8%) and change it to a decimal: .08. You then multiply the decimal (.08) by your other number (in this case $600) and the resulting number is your answer, but not final. Take whatever the answer was (in this case 48) and add it to the orignal number (600) to get $648.

1: A man owns 50 shares of stock worth $30 each. The corporation declared a dividend of 6% payable in stock. How many shares did he then own?
Answer:
53 shares
Step-by-step explanation:
Calculation for how many SHARES did he then own
Using this formula
Numbers of shares=[ (Dividend percentage payable in stock ×Shares of stock)+Shares of stock]
Let plug in the formula
Numbers of shares= [(.06 x 50 shares)+50 shares]
Numbers of shares= 3 + 50 shares
Numbers of shares = 53 shares
Therefore How many shares did he then own is 53 shares

What is the solutions of the following system of equations.
y = -2x + 2
y = x - 1
Answer:
x = 1, y = 0
Step-by-step explanation:
Given the 2 equations
y = - 2x + 2 → (1)
y = x - 1 → (2)
Substitute y = x - 1 into (1)
x - 1 = - 2x + 2 ( add 2x to both sides )
3x - 1 = 2 ( add 1 to both sides )
3x = 3 ( divide both sides by 3 )
x = 1
Substitute x = 1 into either of the 2 equations for corresponding value of y
Substituting into (2)
y = 1 - 1 = 0
Solution is (1, 0 )

The perimeter of the polygon is 12 in. What is the length of side x?
Answer:
2in
Step-by-step explanation:
Since we are not given the type of polygon, let the polygon be an hexagon. An hexagon is a 6 sides shape. The perimeter of the shape will be the sum of all the sides of the polygon
Perimeter of the polygon = 6L
Length is the length of the side
Given
Perimeter of the polygon = 12in
Substitute and get L
P = 6L
12 = 6L
L = 12/6
L = 2in
Hence the length of side x of the polygon is 2in

One week, Ethan earned $391.00 at his job when he worked for 23 hours. If he is paid the same hourly wage, how many hours would he have to work the next week to earn $102.00?
Answer:
6 hrs.
Step-by-step explanation:
So 391.00 can just be converted to 391 because they mean the same thing, so since we have $391 for 23 hrs, we can divde those, which gives us 17, this answer would show that Ethan earns $17 a hour, so if we divide how much he earns by the hour by how much money he could earn by next week ( 102/17), that would give us 6, Therefore, Ethan would need to work 6 hours for $102.00
