Answer:
The answer would be D t is less than or equal to 375
Step-by-step explanation:
Because he wants to save 275 and 275+375 is 650. so if he wants to save at least 275 he can only spend a max of 375.
24 x O = 72
You’re looking for an equation where 24 is multiplied by a number to equal 72, so put 72 on one side of the question and multiply 24 by a variable on the other.
72.5+32.7= 105.2
Triangle angles have to equal 180
180-105.2= 74.8
Third angle= 74.8 degrees
