A recipe calls for 4cups of flour for 12

Mathematics
1 answer:
Dmitriy789 [7]3 years ago
7 0

Answer:

15 muffins

Step-by-step explanation:

We can use proportion to solve this.

Let x be the number of muffins that can be made with 5 cups of flour

4 cups = 12 muffins

5 cups =   x

cross-multiply

4×x = 12 × 5

4x = 60

Divide both-side of the equation by 4

\frac{4x}{4}  =  \frac{60}{4}

(On the left-hand side of the equation, 4 on the numerator will cancel-out 4 on the denominator, while on the right-hand side of the equation 60 will be divided by 4)

x = 15 muffins

15 muffins can be made with 5 cups of flour.

What is the simplified expression for -3(2x- y) + 2y + 2(x+y)2
Step2247 [10]

Answer:

7y-4x.

Step-by-step explanation:

I think that the last 2 shouldn't be there and the third option should be 7y-4x or all the options are incorrect.

-3(2x- y) + 2y + 2(x+y)

= -6x+3y + 2y+2x+2y

= -6x+2x+3y+2y+2y

= -4x+7y.

¿es cierto que si se suman los resultados de la tabla del con los de la tabla del 5 se obtienen los resultados del 7 ¿porque
SSSSS [86.1K]

Answer:

Efectivamente, si se suman los resultados de la tabla del 2 con los de la tabla del 5 se obtienen los resultados de la tabla del 7.

Step-by-step explanation:

Esto es así porque 7 puede formarse a través de diversas sumas (7+0, 6+1, 5+2 o 4+3). Por ende, en el caso de las tablas de multiplicaciones, decir, por ejemplo, 7 x 3, es igual a decir 5 x 3 + 2 x3, dado que 5 + 2 es igual a 7.

Entonces, siguiendo el ejemplo, dado que 7 x 3 es igual a 21, la suma de 5 x 3 igual a 15 y 2 x 3 igual a 6 es 21 (15 + 6), con lo cual la afirmación es correcta.
