Hmm... I would say the equation would look like 3+5x=72/4.
3+5x=72/4
3+5x=18
5x=18-3
5x=15
x=15/5
x=3
The number is 3
9514 1404 393
Answer:

Step-by-step explanation:
The left section is defined at x = -5, but not at x = 0, so the interval for that definition is -5 ≤ x < 0. The function value on that interval is constant: 3.
The right section is defined a x = 5, but not at x = 0, so the interval for that definition is 0 < x ≤ 5. That section is a straight line with a slope of -1 and a y-intercept of 1. The function value on that interval can be written -x+1.
Then the piecewise definition is ...
f(x) = {3, for -5 ≤ x < 0; -x+1, for 0 < x ≤ 5}
Answer:
47.25 ft³
Step-by-step explanation:
The volume of the prism is given by the formula ...
V = Bh . . . . . . . B is the area of the base, h is the height.
The height of the prism is given as 6 ft. The area of the base is the area of the triangular entrance. The formula for that area is ...
A = 1/2bh . . . . . . b is the base, h is the height
Using the given values for the entrance base and height, we get ...
A = 1/2(4.5 ft)(3.5 ft) = 7.875 ft²
Then the volume of the tent is ...
V = (7.875 ft²)(6 ft) = 47.25 ft³
The tent volume is 47.25 cubic feet.
Answer:
0.064
Step-by-step explanation:
25000(1-0.8)^8
= 25000(0.2)^8
= 0.064
Let us manually add the given numbers.
450
790
123
____
1363
Therefore we see that the correct answer 1363 which is far
from what Jill got which is only 1163.
Therefore the answer is No, the sum should be 1363 (closer
to 1400).
