,,hggjj,........,.........
The total number of members should be the sum of the number of men, x, and women, y, and that should be equal to 150. In mathematical equation that should be,
<em>x + y = 150</em>
If we are to note that there are 34 more men than women in the team, we can say that,
y = x - 34
The equation then would become,
x + (x - 34) = 150
The value of x from the equation is equal to 92. With this, the number of the women is equal to 58.
Answer:
has no solution.
Step-by-step explanation:
you can see that the two equations are almost identical except for the fact that one is multiplied by 7, but it isnt completely multiplied correctly so there would be no solutions.
Answer:
17
Step-by-step explanation:
1) if to solve the first inequation, tnen 3x<52; ⇔ x<52/3;
2) if to solve the seconde inequation, then 2x≥24; ⇔ x≥12.
3) according to the items 1 and 2 x∈[12;52/3);
4) the largest prime number is 17.
