Ok so if you notice every choice is solved for a, all you have to do is isolate "a" in 7a-8b=10x. Start by moving 8b to the other side and to change the sign. Now it is 7a = 10x + 8b. Then divide everything by 7 and you get a = (10x + 8b)/7
Ok. So she wants to advertise that there are 100 different dolls available. If she adds another category, then at most she already had 99 different types. If I'm right (don't take my word for it) but the minimum she would have to have is one. <span />
El area total de los 4 cuadrados es 71.86 centimetros cuadrados.

¿Cual es el area total de los 4 cuadrados?</h3>
Recordar que para un cuadrado de lado L, el area es:
A = L^2
Sabemos que el radio del circulo es R = 10.6cm, entonces para los dos cuadrados grandes tenemos:
L = 10.6cm/2 = 5.3cm
Es decir, cada uno de esos cuadrados tiene un area de:
A = (5.3cm)^2 = 28.09 cm^2
Notar que para los cuadrados pequeños, el lado es mayor que la mitad del cuadrado grande, midiendo el lado y comparandolo, veremos que para estos dos cuadrados:
L = 2.8cm
Entonces el area de cada uno de estos sera:
A = (2.8cm)^2 = 7.84cm^2
El area total es:
area = 2*(28.09 cm^2 + 7.84cm^2) = 71.86cm^2

30yards times 25yards is 750 square yards which is almost 8 times the amount one bag covers so Ali would need to buy eight bags of fertilizer to cover the lawn
Since the area of the rectangle is 30, we know the following:
(5)(x-2) = 30
Divide both sides by 5
x-2 = 6
Add both sides by 2
x = 8
That's your answer.
Have an awesome day! :)
