Answer: 1
Explanation: Each child can have up to 13 balloons each. If all 4 children have 13 balloons, that leaves an extra balloon out. 13*4=52, which leaves the 1 extra balloon.
M&0 are similar but not congruent
The answer is x=45... hope I helped!
x/3=15
multiply each side by 3
x=45
Equation: 2x - 6 = 38
Solve for x
Add 6 to both sides
2x = 44, x = 22
The answer is 22
Explication étape par étape:
Compte tenu des expressions ';
A = 4 (x + 5) -8
B = x² + 15
Nous devons vérifier si A = B pour les deux valeurs de x à x = 1 et x = 3
à quand x = 1
A = 4 (1 + 5) -8
A = 4 (6) - 8
A = 24-8
A = 16
B = x² + 15
B = 1² + 15
B = 1 + 15
B = 16
Donc à quand x = 1, A = B = 16
quand x = 3
A = 4 (x + 5) -8
A = 4 (3 + 5) -8
A = 4 (8) - 8
A = 32-8
A = 24
B = 3² + 15
B = 9 + 15
B = 24
Également lorsque x = 3, A = B = 24
Cela montre que le postulat d'Emmas est juste.
