Bianca wrote the steps for her solution to the equation 2.3 + 8(1.3x – 4.75) = 629.9. she left out the description for the last step.
what is the missing step of her solution?
add 10.4 to both sides.
add negative 10.4 to both sides.
multiply both sides of the equation by 10.4.
divide both sides of the equation by 10.4.
mark this and return

 Last Option is correct.

Step-by-step explanation:

Since we have given that

We need to solve the above equation,

Hence, Divide both sides of the equation by 10.4.

Therefore, Last Option is correct.

i'm sure goog can you get that answer

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!
