Answer:
20 < x < 38.
Step-by-step explanation:
An obtuse angle has a value between 90 and 180.
90 < 5x - 10 < 180
5x - 10 > 90
5x > 100.
x > 20.
5x - 10< 180
5x < 190
x < 38
Answer:
29
Step-by-step explanation:
Let's set up an equation...
25%*116=x
We can first convert 25% to a fraction. We can convert any percentage into a fraction by simply putting the number over 100...

We can simplify 25/100 by dividing the fraction by 25/25. Note we can only do this because 25/25 is equivalent to 1, therefore meaning we are dividing the fraction by 1.

C. 14•8 over 2.
A= bh over 2
Not sure what index form is but
48=2 times 2 times 2 times 2 times 3
this is also
48=2^3 times 3
The amount one person will pay for a day is $4
The amount two people will pay for a day is $8
The amount Beth paid for 3 days is 4*3=12
The amount Maria paid for 3days is also 4*3=12
So to find the amount they will pay for 3days, add 12 and 12 to get 24.
The girls will pay $24 for the 3days.
Hope it helps
