It is a 4 by 5 because 4 times 5 eguels 20
Answer:
Step-by-step explanation:
You didn't list any choices here, but it doesn't matter. There's only one way to get to the answer so we'll work it through and you can match it up to your choices. The only thing I don't know is how pens is identified if pencils is "p". So I'm going to use the words "pens" and "pencils" and you can take it from there at the end.
If a pen's cost IS twice as much as a pencil...
the word "is" indicates an equals sign, the words "twice as much" indicates 2 multiplied by something. To put that above sentence into an algebraic expression:
pen = 2 pencils
Now for the money part of this.
The total cost of 11 pens and 11 pencils IS (there's that word again!) 2.10
Therefore,
11 pens + 11 pencils = 2.10
But we know from the first expression that pen = 2 pencils so we make the substitution:
11(2 pencils) + 11 pencils = 2.10
I'm not sure how far you are to go with this. That's the main equation you need to solve this. If you were to go further with it you would distribute the 11 into the set of parenthesis to get:
22 pencils + 11 pencils = 2.10 and combine like terms:
33 pencils = 2.10 so
1 pencil is approximately $.06
Answer:its a zero slope or you can do x2-x1 and y2-y1 and if its an even fraction try simplifying it .
Step-by-step explanation:
Since 10 cm is bigger than 1 mm, the scale drawing is bigger
What goes into the bowl . . .
-- granola . . . 9-1/3 pounds
-- nuts . . . . . 9-1/3 pounds
-- raisins. . . . 9-1/3 pounds
How much is in the bowl all together ?
(9-1/3) + (9-1/3) + (9-1/3) = 27-3/3 = <em>28 pounds</em> .
After stirring, mixing, shaking, and resting, how much is
still in the bowl ?
Still 28 pounds. Nothing else went in, and nothing came out.
After a month, nobody has come into the store yet asking to buy
28 pounds of trail mix. So before it spoils or gets soggy, they decide
to split it up into 14 smaller packages, and see if more people will
buy smaller packages.
They make all of the small packages exactly equal.
How much trail mix is in each one ?
(28 pounds) divided by (14 packages) = <em>2 pounds/package</em>
