Answer:
about 41.14 pages per day
Step-by-step explanation:
She wants to read 576 pages in 14 days
Take the number of pages and divide by the number of days
576/14=41.14285714 pages per day
Answer:
1. Incomplete
2. 8≥ 3 x + 5
⇒8-5≥3 x
⇒ 3 ≥ 3 x
Dividing both sides by 3
1≤ x or x ≥ 1 is the solution of above inequality.i.e x∈[1,0).
The solution of the above inequality is that x lies in the interval from 0 to 1 represented as 0≤x<1.
3. -2 x + 3 > 3(2 x - 1)
⇒ -2 x + 3> 3× 2 x - 3× 1 ⇒ [using distributive property which is a(b+c)=a×b + a× c]
⇒-2 x - 6 x > -3-3 →[ Bringing like terms together]
⇒ - 8 x > -6
Cancelling negative sign from both sides
if ,-a>-b, then a<b.
⇒8 x< 6
⇒x<6/8
⇒x<3/4
x∈(-∞,3/4)
The solution of the above inequality is x should be less than three by four.
Answer:
D. divide 12 from both sides
Step-by-step explanation:
12x = 60,
Divide each side by 12
12x/12 = 60/12
x = 5
