Chords de, ef, and fg are congruent.

circle c is shown. line segments c d, c e, c f, and c h are radii. secants d e, e f, and f g are congruent. angle h c d is 75 degrees, angle e c d is 67 degrees, and angle c f g is 56.5 degrees.

determine the following measures.

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!

this may not be at all, but i use the same website you're using for school, and if i'm stuck doing one of these i try to look for it on the section.
