El ala triangular de una aeroplano se abre hacia atrás con un angulo de 51.5° con respecto a la linea central del fuselaje. Si el borde principal del ala es de 8.62m de longitud y el fuselaje tiene 1.28m de ancho, ¿Cuál es la envergadura (distancia entre las puntas de las alas) del aeroplano?

3

step-by-step explanation:

in standard form:

a= dictionaries

b= maps

you have to buy 3 dictionaries, so put a 3 next to the a (dictionaries) so that you can multiply them by each other.

a3+b= 60 (the amount of money you have)

we already know the cost of a=15 so replace a with $15

($15 x 3)+b=60

multiply 15 and 3 to get $45 and replace it with $45

45+b=60

and then replace b with 15 to get the total:

45+15=60

that means you have $15 left after buying 3 dictionaries.

15 divided by the cost of a map ($5) equals 3.

so you can buy 3 maps.

sorry if it was confusing!

can you rephrase the question ? it is unclear : -)
