Answer:
x =35
Step-by-step explanation:
The sum of the angles of a triangle add to 180
x+10 +x + 3x-5 = 180
Combine like terms
5x+5 = 180
Subtract 5 from each side
5x+5-5 =180-5
5x = 175
Divide by 5
5x/5 =175/5
x =35

Answer:
C) 2/5×1/4
Step-by-step explanation:
Dividing by a number is the same by multiplying by the reciprocal of the number.
For Example:
1/2 divided by 3 would be the same as 1/2 x 1/3
So for this problem we are given that 2/5 is divided by 4 which would be the same as 2/5 multiplied by the reciprocal of 4 which is 1/4 and thus the answer is option C which is 2/5×1/4
