Question

13 times the sum of a number and 2.6 is 4.9

Answer 1

Step-by-step explanation:

13 *x+2.6=4.9

13x+33.8=4.9

13x=4.9-33.8

13x=-28.9

x=-28.9/13

x=-2.22

Answer 2

Answer:

The number is 2.22

Step-by-step explanation:

Here we have been given to find the number whose 13 times the sum with 2.6 gives the value of 4.9 Now for this we assume the number to be n and according to the above-given question we have;

13(n+2.6) = 4.9

⇒ 13n + 13 × 2.6 = 4.9

⇒ 13n + 33.8 = 4.9

⇒ 13n = 4.9 - 33.8

⇒ 13n = - 28.9

⇒ n = -28.9 ÷ 13

⇒ n = 2.22

Therefore the number is 2.22
