#3.

Triangle RCH is congruent to Triangle NCH by SAS.

Side 1 - reflexive (CH)

Angle - given

Side 2 - given

#4.

Triangle SOK is congruent to Triangle XAM by ASA.

Angle 1 - angle X is 53 degrees, as is angle S

Side - given

Angle 2 - angle A is 103 degrees, as is angle O

Hope this helps!

the answer is y < -3 or   y > 3

-3y > 7 + 2

-3 y > 9

y < -3

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!
