Answer:
14
Step-by-step explanation:
12< average >16
14 is the only one in between 12 and 16.
or.....................................................................................................
12 + 16 + 13 = 41.
41/3 = 13 2/3.
13 2/3 rounds to 14 and it's the closest to it.
HOPE IT HELPS!!! :)
If Karen works 1 hour, she prepares 2 kg of dough.
If Karen works 2 hours, she prepares 2 kg + 2 kg of dough.
Maybe you can see where this is going.
If Karen works 3 hours, she prepares 2 kg + 2 kg + 2 kg of dough.
If Karen works h hours, she prepares 2 kg + 2 kg + ... + 2 kg of dough, where the number of instances of 2 kg is equal to h.
Early in your math career, you learned that repeated addition can be represented by multiplication. That is, when Karen works 3 hours, she prepares 3*(2 kg) of dough. It is not that big of a stretch to see that when Karen works h hours, she will prepare h*(2 kg) of dough.
Karen's output = h*(2 kg) . . . . . . an equation for finding the amount of dough
You are asked to solve this when h=5.
Karen's output = 5*(2 kg)
Karen's output = 10 kg
If she works 5 hours, Karen can prepare 10 kg of dough.
Answer:
I am sure that answer is 18.
I hope you got it
Step-by-step explanation:
So let's make the two numbers "X" and "Y".
X + Y = 5
That's the very first line
let's take X as the bigger number and Y as the Smaller number.
3x + 2y = 28
now we have two equations and two unknowns.
We can also arrange the first equation to be as
X = 5 - Y
substitute this equation in the 2nd equation
3(5- Y) + 2Y = 28
15 - 3Y + 2Y = 28
-Y = 13
Y = -13
Substitute Value of Y in any equation to get X
X = 5 - (-13)
X = 18
Answer:
x=6
Step-by-step explanation:
if you cross multiply, you get 8(x-4)=2(x-2)
Multiply the terms and you get: 8x-32=2x-4
Now you should move the terms around so all of your x's are on one side, and you'll be left with 6x=36.
Divide both sides by 6 so the x is by itself, and x=6
