When two fractions refer to the same whole explain why the fraction with a lesser denominator has larger pieces than the fractio

dexar [7]

Because there are less pieces the whole is split up into. For instance, if you have 1 bag of cookies, you would get more cookies per person if it was split between 2 people than if it was split between 10, because each person gets more of the whole, and there's less people to split up that whole.
since you have an equal amount of pieces from each, the whole that was split into the least pieces, or the number with the smaller denominator will be larger since the pieces will be larger

One pretzel has 20 calories. Write an algebraic expression for the total number of calories in n pretzels.

vredina [299]

Answer:

20n

Step-by-step explanation:

One pretzel has 20 calories. Write an algebraic expression for the total number of calories in n pretzels.

1 pretzel = 20 calories

n pretzel = x

Cross Multiply

x × 1 pretzel = n pretzel × 20 calories

x = n pretzel × 20 calories/1 pretzel

x = 20 n

Therefore, an algebraic expression for the total number of calories in n pretzels = 20n

What is the solution to –2(5y – 5) – 3y ≤ –7y + 22?

Gre4nikov [31]

-2(5y - 5) - 3y < = -7y + 22
-10y + 10 - 3y < = -7y + 22
-13y + 10 < = -7y + 22
-13y + 7y < = 22 - 10
-6y < = 12
y > = -12/6
y > = -2....answer B

the linear equation y=2x represents the cost y of x pounds of pears. which order pair lies on the graph of the equation? A. (2,4

Vladimir [108]

Answer:

A. (2, 4)

Step-by-step explanation:

The ordered pairs represent (x, y). Since you have y =2x, this is the same as ...

(x, 2x)

That is, the second number in the pair needs to be twice the first number in the pair. Since you know your times tables, you know that this is not the case for (1, 0), (10, 5) or (4, 12). Those values of x would give (1, 2), (10, 20), (4, 8).

It is the case that you have (x, 2x) for (2, 4).

The point (2, 4) lies on the graph of y = 2x.
