Idon't know what to do for this one

Let, number of sold Pizza = x
Number of sold sub-sandwiches = x+13

So, equation would be: 6x + 4(x+13) = 262
6x + 4x+52 = 262
10x = 210
x = 210/10

x = 21  (Number of Pizza)
z+13 = 34 (Number of Sub-sandwiches)

Hope this helps!

The second step on the test was the move he was supposed to

This polygon has 4 sides
180(4-2) = 180(2) = 360 degree
80+90+2x + 3x = 360
170+5x = 360
5x = 190
x= 38
measure of angle t is 2(38)= 76
the answer is c. trust me
hope this !
