Answer:
Step-by-step explanation:
A+B+C = 180°
A ≤ B ≤ C
B = A+9
C = 3A+26
A+B+C = A + (A+9) + (3A+26) = 5A + 35° = 180°
5A = 145°
A = 29°
B = A+9 = 38°
C = 3A+26 = 113°
Find the common denominator first--> 10
1/2= ?/10 ?=5
so 5/10 +9/10 (Now you just add the numerators and keep the common denominator the same)
14/10 and if you want to simplify it, simply divide both the top and bottom by 2
answer = 7/5
To estimate, you would usually round to a significant figure
so, 20* 70=1400
The actual answer is 1521, so we know we are close
Answer:
Step-by-step explanation:
use distance formula (x2-x1) + (y2-y1)-----> (4-1)+ (5-Y)=3x3+ 5y=
6+5y=6/5=1.2
y=1.2?
