Five is added to three more than a certain number, resulting in 19

5 + 3 + (x) = 19

8 + x = 19

x = 19 - 8 = 11


Thus, the certain number is 11.

Mazyrski [523]

Answer:

9

Step-by-step explanation:

Let corn tortillas be represented by c, flour tortillas be represented by f and the total number of packages be t

such that

t = c + f     .... eq 1

ratio of c to t = 7 : 16 = 7/16

Therefore, t = 16,    c = 7

substitute the value of t in eq 1

16 =  7 + f

f = 16 - 7

f = 9

Please can someone help me?
Debora [2.8K]
If the perimeters are equal, you can form an equation to find x:
x + x + 12 + x + x + 12 = x + 11 + x + 11 + x + 16
4x + 24 = 3x + 38
- 3x
x + 24 = 38
- 24
x = 14
Now you can substitute the x value into the perimeter:
(4 × 14) + 24
56 + 24 = 80 cm

(3 × 14) + 38
42 + 38 = 80 cm

So the perimeter would be 80 cm.
I hope this helps!
