The answer will going to be A
Let present age of women be x.
Then,Present age of her daughter be y.
According to the question,
<u>Two years ago,</u>
Woman age = x - 2
Her daughter age = y - 2
Woman was 7 times old as her daughter. [ Given ]
x - 2 = 7 ( y - 2 )
=> x - 2 = 7y - 14
=> x - 2 + 14 = 7y
=> x + 12 = 7y ....( i )
<u>A</u><u>f</u><u>t</u><u>e</u><u>r</u><u> </u><u>Three years </u>,
Woman age = x + 3
Her daughter age = y + 3
she would be 4 times old as the girl. [ Given ]
x + 3 = 4 ( y + 3 )
=> x + 3 = 4y + 12
=> x = 4y + 12 - 3
=> x = 4y + 9....( ii (
Now,
★ Putting the value of x = 4y + 9 from equation ( ii ) in equation ( i ),we get
x + 12 = 7y
=> 4y + 9 + 12 = 7y
=> 21 = 7y - 4y
=> 21 = 3y
=> 3y = 21
=> y = 21/3
=> y = 7
And,
x = 4y + 9
★ Putting the value of y in equation ( ii ), we get
x = 4 × 7 + 9
x = 28 + 9
x = 37
Hence, the present age of women is 37 years and her daughter age is 7.
In y = mx + b form, the slope will be in the m position and the y int will be in the b position
y = mx + b
slope(m) = 8
y int (b) = 12
sub
y = 8x + 12
now, to find the x int, sub in 0 for y and solve for x
0 = 8x + 12
-8x = 12
x = -12/8 which reduces to - 3/2....so ur x int is -3/2 or (-3/2,0)

Answer:
182 lbs
Step-by-step explanation:
You can write the proportion for the required patient weight (w) as ...
weight/medicine = w/(174.72 mg) = (150 lb)/(144 mg)
w = (150 lb)(174.72/144) . . . . . multiply by 174.72 mg
w ≈ 182 lb
The patient's weight is 182 pounds.
First, we need to see what 0.82 is as a fraction, regardless of it being simplified or not. To do this, we can just place it over 100 (because the decimal goes to the hundredths place). Once we have 82/100, we can divide both the numerator and denominator by 2 to get 41/50, which is the simplest form of this fraction.
Therefore, 0.82 is 41/50 as a simplified fraction.
