Answer:
28
Step-by-step explanation:
63/9=7
7*4=28
Answer: See below
Step-by-step explanation:
Isolate x for x-2y+2z=9
3x=9+2y
....(1)
Substitute (1) into the 2nd equation
7y=-3
y=-3/7
Substitute y=-3/7
Isolate z by substituting it
For x =9+2y/3 substitute z=59/21 and y=-3/7
We assume a linear system with 2 variables.
If the slopes are the same, and y-intercepts are different, there are 0 solutions.
If the slopes are different, there is 1 solution.
If the slopes are the same, and the y-intercepts are the same, there are ∞ solutions.
Answer: I think the answer is 80x + 60y < or equal to 1,000 (the first answer)
Step-by-step explanation:
because the person doesn't want to consume more than 1,000 mg
Answer:
Nikki grows 20 tomato plants and she measures their heights.
We want to complete the frequency table.
All we have to do is count the number of values that fall between each range.
The values are:
5 10 12 16 14
17 20 15 10 7
13 11 6 18 15
6 12 17 8 12
Height Frequency
-> 5 ≤ h < 10 5
10 ≤ h < 15 8
15 ≤ h < 20 6
20 ≤ h < 25 1
