Step-by-step explanation:
Let Freddy could arrange n catalogs on the shelf.
The dimension of the shelf is:
72 over 5 inches wide.
The dimension of the catalog is:
4 over 5 of an inch thick.
n × Dimension of one catalog=Dimension of shelf.
i.e.
n×(4 over 5 inches)=72 over 5 inches
i.e.
n=72 over 5 inches/ 4 over 5 inches
i.e.
n=72/4
i.e.
n=18
Let the numbers be 2x and 3x.
<u>According to the Question</u>,
⇒ 2x + 3x = 45
⇒ 5x = 45
⇒ x = 45/5
⇒ x = 9
<u>Now finding the values of both the number,</u>
⇒ 2x = 2 × 9
= 18
⇒ 3x = 3 × 9
= 27
<u>Hence, the value of both the number is 18 and 27 respectively.</u>
Answer:
X = 45
Step-by-step explanation:
90 + X + A = 180 (angles of a triangle sum to 180)
90 + X + 45 = 180
X = 45
It’s using the distributive method. 7 x a is 7A and 7 x 13 is 91, therefor it is 7A+91.
