Hey there!!
A chicken has 1 head and 2 feet . A goat has 1 head and 4 feet
For heads, total = 40
Let us take the number of chickens as ' x ' and goats as ' y '
x + y = 40 ------------- ( 1 )
2x + 4y = 150 ----------- ( 2 )
Multiply the first equation with 2
2x + 2y = 80
2x + 4y = 150
Subtract the first equation from the first
2y = 70
y = 35
Number of goats = 35
substitute this in other equation
x + y = 40
x + 35 = 40
x = 5
Number of chickens are 4
Hope it helps!
Answer:
i think it is no
Step-by-step explanation:
because 1+4=5
and girls are one so i think it is 1/5
hopefully i am right
Answer:
17 units
Step-by-step explanation:
We are told in the question that:
The patient has been receiving 20 units of Lantus.
The order reads that if your patient is NPO, reduce Lantus by 15% , because. now the patient has become NPO (nothing through the mouth) for surgery
The amount to units to reduce Lantus by is calculated as:
15 % of 20 units
= 15% × 20 units
= 3 units.
Hence, if a patient is NPO the Lantus is reduced by 3 units
The number of units of Lantus should the patient receive now that he is NPO
is calculated as
= 20 units - 3 units
= 17 units.
Therefore, the number of units of Lantus should the patient receive now that he is NPO is 17 units.

Brainliest Answer would be appreciated. Option 1 is the best
Step-by-step explanation:
The slope of the line on the graph is -1/3. A perpendicular line's slope is always the negative reciprocal of it, so your slope of the perpendicular line would be 3.
Also, since you are passing through the point (0, -2), -2 would be your y-intercept, making your equation for the perpendicular line y = 3x - 2.
