Answer:
x = -2, y = -1, z = 4
Step-by-step explanation:
4x + 6y - z=-18
z = 18 + 4
x + 6
y
3x +2y - 4z = -24
z = 6 + (3x)/
4 + y
/2
- 5x + 3y + 2z = 15
z = 15/2 + (5x)/2 - (3y)/2
18 + 4
x + 6
y = 6 + (3x)/
4 + y
/2 = 15/2 + (5x)/2 - (3y)/2
x = -22y/13 - 48/13
4(-22y/13 - 48/13) + 6y - (15/2 + (5(-22y/13 - 48/13))/2 - (3y)/2) = -18
Compute the output value of the variables x and y with respect to the input values of x, y, and z coefficients.
Answer:
C.
Step-by-step explanation:
-2 is in front of x so thats gonna be the slope
and +3 is the y-intercept
So from these given details will be right choice A. sure because given that 1 unit cube = 1 inch so from this result that 48 unit cubes = 48 cubic inches
hope this will help you
Given:
Budget for tiles = 1,200
number of white tiles = 38
unit cost of white tiles = 12
budget for brown tiles = x
cost of white tiles = 38 x 12 = 456
The inequality would be:
Cost of brown tiles + cost of white tiles <u><</u> budget
x + 456 <u><</u> 1,200
solving the inequality:
x + 456 <u><</u> 1,200
<u> - 456 -456</u>
x <u><</u> 744
Mr. Jacobs can spend up to 744 for the brown tiles.
Answer:
Probability of the next spin landing on colour purple = (1/5) = 0.20
Step-by-step explanation:
Complete Question
A spinner is divided into four colored sections that are not of equal size: red blue purple and orange. The results of a number of spins is given as
Orange: 9
Red: 15
Blue: 24
Purple: 12.
The arrow on the spinner will be spun one more time. Based on these results, what is the probability that the arrow will land on the purple section?
The probability of an event based on trials is given as the number of successes for that event, n(E), divided by the total number of trials, n(S)
P(R) = n(E) ÷ n(S)
Number of successes for the spinner landing on purple = 12
total Number of trials = 9 + 15 + 24 + 12 = 60
Probability of the next spin landing on colour purple = (12/60) = (1/5) = 0.20
Hope this Helps!!!
