Answer:
Kayla
Step-by-step explanation:
To find who spend the least amount of time on homework per hour, divide the number of hours by the amount of homework
Kayla: 3.2 ÷ 4 = 0.8
Karen: 5 ÷ 6 = 0.833
Since Kayla's number is lower, that means she spent fewer hours per homework than Karen. This means Karen spent the least amount of time in hours per homework.

2 (x + 6) = 36 what’s is x
Answer:
12
Step-by-step explanation:
distribute the 2, turning the equation into 2x+12=36
subtract 12 from both sides, now resulting in 2x=24
then divide by 2
Step-by-step explanation:
2(x+6)=36
2x+12=36
collect like terms
2x=36-12
2x=24
divide both sides by 2
2x/2=24/2
x=12
Can you still use the triangle sum Theorem even if a triangle is not in 180 degrees?
Hi!
You cannot.
This is because ALL triangles MUST have 180 degrees, so if it doesn't it's not even a triangle. Therefore you cannot use it because, well, it's not a triangle.
Answer:
The sum of interior angles is 180 degrees (Triangle Angle Sum Theorem). All interior angles of a triangle are more than 0° but less than 180°.

Answer:
x = 12/7
Step-by-step explanation:
You put: What you should have had is:
13x - 3y = 12 13x - 3y = 12
- x + 3y = 12 + x + 3y = 12
Now that we have that, we can do
14x = 24
Than, divide 24 by 14
x = 24/14
which we can simplify by dividing both by 2
x = 12/7
We can't simplify it down anymore, so this is our answer.

Below are the supply and demand equations for blenders in a certain market. In these equations, p represents price, D represents demand, and S represents supply.

The value of p at the point of equilibrium, where supply and demand are equal, is 43.3 (the nearest tenth).
What is equilibrium point of supply and demand?The equilibrium point of supply and demand is the point where, the value of demand of a product is exactly equal to the value of supply of that product.
The supply and demand equations for blenders in a certain market is given as,
[tex]D=\dfrac{-5}{8}p+35[/tex]
[tex]S=\dfrac{6}{5}p-44[/tex]
Here, in these equations, p represents price, D represents demand, and S represents supply.
At the point of equilibrium, the supply and demand are equal. Therefore,
[tex]D=S\\\dfrac{-5}{8}p+35=\dfrac{6}{5}p-44[/tex]
Solve it further to get the value of p as,
[tex]\dfrac{6}{5}p-\dfrac{-5}{8}p=35+44\\\dfrac{6}{5}p-\dfrac{-5}{8}p=35+44\\p=\dfrac{3160}{73}\\p\approx43.3[/tex]
Hence, the value of p at the point of equilibrium, where supply and demand are equal is 43.3 (the nearest tenth).

Karen wants to buy 5 pounds of baby carrots. The packages of carrots each weigh14 ounces. How many will she need to buy to reach 5 pounds
Answer:
I think it's 70
Step-by-step explanation:
if this is multiplication I just did 14x5 if it's wrong or someone want to correct me pls do or pls tell me thank you have a great day!
Answer:
6 packages
Step-by-step explanation:
First, let's list an important conversion. 1 pound = 16 ounces.
For the sake of this explanation, and because I think this is mathematically easier to deal with, we are going to be dealing in ounces.
So, step one, convert 5 pounds to ounces. For this, we just multiply 5 by 16 to get 80.
Now, we know each package of carrots weighs 14 ounces each. Since we need to see how many times 14 goes into 80 (remember, 80 is the same as 5 pounds), we use division.
80/14 = 5
But, hey! You can/t buy 5/7ths of a package. So we need to buy an ENTIRE EXTRA PACKAGE just to make up for it.
So we round our number up to 6.
