You have to move the decimal
Answer:
Step-by-step explanation:
= [ - ] ← evaluate for upper limit - lower limit
= ( - ) - ( - )
= - 8 - 9 +
= - 17

Answer:
For number 1: y=2 and x=3
Answer:
Angle ADC = 80 degrees
Step-by-step explanation:
Here, we want to find the measure of angle ADC
mathematically, sum of angles at a point is 360
Thus;
x + 3x + x + 10 = 360
5x + 10 = 360
5x = 360-10
5x = 350
x = 350/5
x = 70
From the diagram;
angle ADC is (x + 10)
so we have; (70 + 10) = 80 degrees
Pretty sure it’s 1/9
1/3 = 3/9
1/9 is 1/3 of 1/3
Answer= 1/9
