Answer:
16=d-12/14
We simplify the equation to the form, which is simple to understand
16=d-12/14
Simplifying:
16=d-0.857142857143
We move all terms containing d to the left and all other terms to the right.
-1d=-0.857142857143-16
We simplify left and right side of the equation.
-1d=-16.8571428571
We divide both sides of the equation by -01 to get d.
d=16.8571428571

Answer:
20, 4
Step-by-step explanation:
Let's assume total number of students registered is n
Last week n/4 people are absent
so people present are n - n/4 = <u>3n/4</u>
Today after return of Jen 1/5 n are absent
so people present are n - n/5 = 4n/5
which is also equal to last week present people + 1 (Jen)
= 3n/4 + 1
= (3n + 4) / 4
so (3n + 4) / 4 = 4n/5
=> 3n + 4 = 4n/5 * 4
=> (3n + 4) * 5 = 16n
=> 15n + 20 = 16n
=> 20 = n
=> n = 20
So total students registered for class is 20
today no of people absent = n/5 = 20/5 = 4
#4)
cross multiply
2(8x+10) = 4 * 5x
16x + 20 = 20x
4x = 20
x = 5
Answer:
<u>ACUTE</u><u> </u><u>TRIANGLE</u><u> </u>
Step-by-step explanation:
If the sum of the squares of the two shorter sides of a triangle is greater than the square of the longest side, the triangle is acute. However, if the sum of the squares of the two shorter sides of a triangle is smaller than the square of the longest side, the triangle is obtuse.
Therefore, the triangle with sides 11, 9, and 7 is an acute triangle since 9² + 7² is greater than 11²
3.5, 3.95, 3.975
Ordered from least to greatest.
