Graph?
well
for
|a|>b solve
a>b and a<-b
|4w+1>11
solve
4w+1>11 and 4w+1<-11
minus 1 both sides
4w>10 and 4w<-12
divide both sides by 4
w>5/2 and w<-3
graph the points -3 and 2.5
shade outside
not including
2.
union means include all common to both
so
2. 1,2,3,4,6,8,9
3. 1,2,3,4,5,7,10
4. interseciton so only ones common to both, so 4
5. null set (empty)
Answer:
40
Step-by-step explanation:
5(8)
The clues translate to
n/d = 2/3
(n+2)/(d+2) = 3/4
Solving this by cross multiplying both:
3n = 2d
3(d+2) = 4(n+2) => 3d + 6 = 4n + 8
then substituting d = 3/2 n in the second:
9/2n - 4n = 2 => 1/2 n = 2 => n = 4
if n=4 then d = 3/2*4 = 6.
So the original fraction was 4/6
Perimeter is 34.5 area is 62
Step-by-step explanation:
after 60% reduction he paid 40% of its price=224
224×100=40×?
?=560
