Answer:
80% are 15 years old
Step-by-step explanation:
To find the percent , we need to know how many out of 100
20/25
Multiply the top and bottom by 4
20*4
-----------
25*4
80/100
This is 80%
80% are 15 years old
I'm assuming you are finding the equation of the line of Line J
Slope-intercept form: y = mx + b
[m is the slope, b is the y-intercept or the y value when x = 0 --> (0, y) or the point where the line crosses through the y-axis]
For lines to be perpendicular, the slopes have to be negative reciprocals of each other. (basically changing the sign (+/-) and flipping the fraction/switching the numerator and the denominator)
For example:
slope = 2 or 
Perpendicular line's slope =
[changed sign from + to -, and flipped the fraction]
slope = 
Perpendicular line's slope =
[changed sign from - to +, and flipped the fraction]
Since you know the slope is 3, the perpendicular line's slope is
. Plug this into the equation
y = mx + b
To find b, plug in the point (3, 8)

8 = -1 + b Add 1 on both sides to get "b" by itself
8 + 1 = -1 + 1 + b
9 = b

Answer:
-8
Step-by-step explanation:
If 3x-4y=2, then for any number a we also have a(3x-4y)=a(2) by multiplication property of equality.
Therefore, for a=-4 we have -4(3x-4y)=-4(2) which means the value of -4(3x-4y) is -8.
Answer:
4 ounces
Step-by-step explanation:
46/92 is one half so the recipe out of 100 is divided in half
8/2=4
the recipe also doesn't sound to appetizing
