8 ( 4 - x ) = 7x + 2
32 - 8x = 7x + 2
      -7x     -7x
--------------------------
32 - 15x = 2
-32           -32
----------------------------
-15x = -30
/-15      /-15

x = 2.

Répondre:

r <27

Explication étape par étape:

Compte tenu de l'inégalité 5r + 9> 10r - 126

Nous devons trouver l'ensemble de solutions

5r + 9> 10r - 126

Ajouter 126 des deux côtés

5r + 9 + 126> 10r - 126 + 126

5r + 135> 10r

5r-10r> -135

-5r> -135

Divisez les deux côtés par -5 (notez que le signe changera)

-5r / -6 <-135 / -5

r <27

Par conséquent, les ensembles de solutions sont des valeurs inférieures à 27

Strike441 [17]
The whole number of minutes that Gianna complete each week as a function of x and y:
45x+30y
Since the above number is greater than 450 minutes, we get the inequality:
45x+30y\geq450
Also, "she can complete at most 10 workouts this week" so we deduce the inequality:
\\x+y\leq10
Therefore, the system of inequalities is the following:
45x+30y\geq450
\\x+y\leq10
The above system has many solutions, for example :
