For this case we have that each student takes 8 \ frac {3} {4} minutes to perform and play 3 songs. Then, we convert the mixed number to a fraction:
Thus, each student takes
minutes.
If there are 9 students in the recital then we have:
minutes.
Thus, the recital lasts at least 78.75 minutes.
Answer:
The recital lasts at least 78.75 minutes.
Answer:
X= - 44
18x+3x+4-5=5(4x9
Collect like terms
21x+4-5=5(4x-9
More variable to the left hand side and change its sign
21x-20x-1=-45
Correct like terms
X=-45+1
Which is x=-44
Answer:
Step-by-step explanation:
- Measure of angle J K H + measure of angle J K L = 180 degrees
True.
- Measure of angle J K L + measure of angle J L K + measure of angle K J L = 180 degrees
True. The sum of all interior angles = 180
- Measure of angle J K H = measure of angle J L K =
Can't tell from info given.
- Measure of angle J K L + measure of angle J L K = 90 degrees
Can't tell from info given.
- Measure of angle K J L = measure of angle K L J

- I think it's possibly this "The figure must be a square because the diagonals of a square bisect the right angles." but there's also "The figure must be a rhombus because it has exactly 2 pairs of congruent angles." buuut since the first one seems more better i'm assuming then that's probably the right answer.
Answer:
2x^2 + 6.
Step-by-step explanation:
Replace the x in f(x) by g(x):
f(g(x)) = 2(x^2 + 3)
= 2x^2 + 6.
