7 and 1/4 divided by 5/6 as a fraction or mixed number in simplest form
Alchen [17]
First off, turn 7 1/4 into a mixed number, 29/4. change 29/4  /  5/6   into a multiplication question by flipping 5/6 into 6/5 (AKA multiplying by the reciprocal) so you get 29/4  X  6/5. then multiply so you get 174/20. Next, simplify into a mixed number by seeing how many times 20 goes into 174, and then putting the leftovers into a fraction, so you get 8 14/20, then simplify even further so you get 8 7/10.

Rewrite the equation 2y - 4x = 10 in function notation where f(x)= y.<br> f(x)=
Vladimir [108]

Answer:

Answer:

f(x) = 5 + 2x

y+4x^2-1 is the same as y=-4x^2+1, then replace y with f(x); f(x)=-4x^2+1. After you do that, replace x with 2; f(2)=-4(2)^2+1. 2^2=4, 4 times -4=-16, -16+1=-15. So f(2)=-15.

Que frações equivalentes a 3/4 tem denominador 65
LuckyWell [14K]

Dada fração: 3/4

Necessidade de converter o denominador em 65.

Vamos supor que x deve estar no numerador (topo) das frações para obter 65 no denominador (abaixo) para obter a fração equivalente de 3/4.

Vamos definir uma atribuição.

\frac{3}{4}=\frac{x}{65}

Deixe-nos resolvê-lo por x agora.

Na multiplicação cruzada, obtemos

4x = 195.

Dividindo ambos os lados por 4, obtemos

x = 48.75

Assim, podemos fazer uma fração equivalente de 3/4, colocando 48.75 no topo do denominador 65.

Então, temos \frac{48.75}{68}
