Take the -3/5 and add it to 1/30 which would equal 19/30, so x= 19/30
Answer:
x =-2.1
Step-by-step explanation:
X/2+10=8.95
Subtract 10 from each side
X/2+10-10=8.95 -10
x/2 =-1.05
Multiply each side by 2
x/2*2 =-1.05*2
x =-2.1
Actually, the area of a triangle is a = bh/2. If a = 30 and b = 12:



So he height is 5 units
