20/100 * 45
1/5 * 45
0.2 * 45
Hope it helps.
Two lines to be parallel their slopes have to be equal.
so m1 = m = 4
y = mx + b ( Slope intercept form)
y = 4x + b
(3,0) is on the line:
0 = 12 + b
b = -12
y = 4x - 12
Responder:
Número total de bolas = 245/23
Explicación paso a paso:
Dado que:
Bolas blancas = 1/5
Bolas negras = 1/7
Bolas rojas = 7
Sea el número total de bolas = x
Bolas blancas = 1 / 5x
Bolas negras = 1 / 7x
Por tanto, total;
(x / 5 + x / 7 + 7) = x
((7x + 5x) / 35) +7 = x
(12x / 35) + 7 = x
7 = x - 12x / 35
7 = (35x - 12x) / 35
7 = 23 veces / 35
245 = 23x
x = 245/23
Answer:
i think that you have to divide each fraction, andmaybe find the other fractions
Step-by-step explanation:
Answer:
a) x = 7.5
b) x = 1
Step-by-step explanation:
a)
- (4x - 1)/2 = x + 7
- 4x - 1 = 2(x + 7)
- 4x - 1 = 2x + 14
- 2x = 15
- x = 15/2 or 7.5
b)
- 3x + 2 = (2x +13)/3
- 3(3x + 2) = 2x + 13
- 9x + 6 = 2x +13
- 7x = 7
- x = 1
