It's scalene because it has different sides and obtuse because root 40²+30²=50
110>50
Given:
The inequality is:

To find:
The solution of the given inequality.
Solution:
We have,

Multiply both sides by 3.

Divide both sides by -8 and change the sign of inequality.


It can be written as:

Therefore, the correct option is A.
The topics you should learn are equating denominators and fractions. This is summing up simple fractions.
So we have to make denominators' numbers the same in order to sum up them all (we can sum fractions if the denominators are the same) , and we did it by cross product (that thing on the picture)
Equating by lcm (least common multiple) is the easiest way, because you might see bigger numbers on other questions, and cross product will bring much bigger numbers, so this technic might confuse you.
By the way lcm of 4 and 5 is already 20

the answer is 75 minutes/1h 15m
15 pages × 350 words = 5250 words
5250 ÷ 70 = 75 minutes (1h 15m)

Answer:
0.1187
Step-by-step explanation:
A = P (1 + k)^t
where A is the final amount,
P is the initial amount,
k is the monthly growth rate,
and t is the number of months.
70 = 50 (1 + k)^3
1.4 = (1 + k)^3
∛1.4 = 1 + k
k = -1 + ∛1.4
k = 0.1187
