x = 15
Step-by-step explanation:
Answer:
Each Novis share 7 sheep and each Expert share 12 sheep.
Step-by-step explanation:
Here, N represent the number of novices and E represent the number of experts needed for the company to meet its goal,
∵ All novices share the same number of sheep per day and all experts share the same number of sheep per day.
Let the sheep per day by a Novice = x and sheep per day by an expert = y,
So, the total sheep = xN + yE
According to the question,
Total sheep ≥ 700
⇒ xN + yE ≥ 700,
By here, we have given the inequality for the given scenario,
7N+12E ≥ 700
By comparing,
x = 7 and y = 12
Hence, Each Novis share 7 sheep and each Expert share 12 sheep.
Answer:
Step-by-step explanation:
Hello,
Imaginary term must be the same so
-2ab=-12
2ab = 12
ab = 12/2 = 6
So the product of a and b is 6
Hope this helps.
Do not hesitate if you need further explanation.
Thank you
I: y=(1/2)x+5
II: y=(-3/2)x-7
substitution:
fancy word for insert the definition of one variable in one equation into the other
-> isolate a variable, luckily y is isolated (even in both equations) already
-> substitute y of II into I (=copy right side of II and replace y in I with it):
(-3/2)x-7=(1/2)x+5
-3x-14=x+10
-3x-24=x
-24=4x
-6=x
-> insert x back into I (or II):
y=(1/2)x+5
=(1/2)*(-6)+5
=-3+5=2
elimination: subtract one equation from the other to eliminate a variable, again y is already isolated->no extra work required
I-II:
y-y=(1/2)x+5-[(-3/2)x-7]
0=(1/2)x+5+(3/2)x+7
0=(4/2)x+12
-12=2x
-6=x
-> insert x back into I (or II):
y=(1/2)x+5
=(1/2)*(-6)+5
=-3+5=2
