Find the value of x.

14

Step-by-step explanation:

add both values and equals them to 180.then solve the equation and find X you will get 14

I think x = 14

Step-by-step explanation:

7x - 1 + 6x - 1 + 7x -1 + 6x -1

(vertically opposite angles are equal)

collect like terms:

26x - 4 = 360

(angles around a point = 360 degrees)

+4 to both sides

26x = 364

x = 14

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!
