Sum means addition. Times means multiplication, and "is" means an equality, or equals. We use a variable to represent the unknown number.

So 7x+7 is the sum of seven times a number and 7. 6x means six times the number. 6x is 7x+7, leading to the final answer 7x+7=6x.

When dividing, the second fraction flips over .

15* 3/1= 45/1= 45

2. 24 / 1/6

24*6= 144

4. 7/12 / 1/3

7/12*3/1

Cross out 3 and 12, divide by 3

12/3= 4

3/3= 1

7/4* 1/1. Multiply the numerator together. Multiply the denominators together.

7*1= 7

Si un rectángulo con perímetro de 74 pulgadas tiene un largo de 5 pies más que el ancho,

baherus [9]

Perímetro del rectángulo = 74 pulgadas

Deje que el ancho del rectángulo sea 'x'.

Entonces, la longitud de este rectángulo = x + 5

We know that :

$\color{hotpink}\tt \: Perímetro \: del \: rectángulo =\color{plum} 2 × (l + b)$

Lo que significa :

$=\tt 2(x + x + 5) = 74$

$=\tt 2(2x + 5) = 74$

$=\tt 4x +10 = 74$

$=\tt 4x = 74 - 10$

$=\tt 4x = 64$

$=\tt x = \frac{64}{4}$

$\color{plum} =\tt x = 16$

Por lo tanto, el ancho de este rectángulo = 16 pulgadas

Entonces, la longitud de este rectángulo :

$=\tt x + 5$

$= \tt16 + 5$

$\color{plum} =\tt 21 \: pulgadas$

La longitud de este rectángulo = 21 pulgadas

<h2>Por lo tanto :</h2>

● Longitud del rectángulo = <em>21 pulgadas</em>

● Ancho del rectángulo = <em>16 pulgadas</em>

icang [17]

We are given the following expression:

$\sqrt[3]{875}$

We can factor 875 as:

$\sqrt[3]{125\times7}$

Now we will use the following property:

$\sqrt[x]{a\times b}=\sqrt[x]{a}\times\sqrt[x]{b}$

Applying the property:

$\sqrt[3]{125}\times\sqrt[3]{7}$

Solving the cubic root on the left:

$5\sqrt[3]{7}$

Since we get simplify any further this is the answer.
