Answer:
x = 24
Step-by-step explanation:
y= -16
-16 x 6 = -96
y= -96
x= 4
4 x 6 = 24
x=24
69.75 x 0.05 = $3.49 discount
$69.75 - $3.49 = $66.26 discounted price with tax
66.26 x 0.18 = $11.93 tip
Discounted price with tax + tip
66.26 + 11.93 = 78.19
Answer:
one side is 40 other is 50
Step-by-step explanation:
perimeter=180cm
let one side=length=x
Acc. to condition:
other side=width=x+10 (one side exceed other by 10)
perimeter= 2(length+width)
subtitue all values given above:
180=2(x+x+10)
180=2(2x+10)
2x+10=180/2
2x+10=90
2x=90-10
2x=80
x=40
now
lenght=x=40cm
width=x+10=40+10
width=50cm
Actually, the area of a triangle is a = bh/2. If a = 30 and b = 12:
So he height is 5 units
