Answer:
Omg my oth acc is gone
Step-by-step explanation:
To solve for the answer of the question above, let x be the number of words on the list. As stated above, 2/3 of this is the number of words Martina needs to memorize which is 12. This may be expressed as,
(2/3)(x) = 12
Solving for x in the equation gives an answer of 18. Therefore, there are 18 words on the list.
Answer:
s = 32
Step-by-step explanation:
First distribute the -5:
-5s + 150 = -10
Add 10 to both sides
-5s = 160
Divide by -5 on both sides
s = 32
Answer:
y = -3x + 8
Step-by-step explanation:
This looks like it's in slope-intercept form.
So, they want you to write it like y=mx+b, where m is the slope and b is the y-intercept.
First, find the slope.
The slope is calculated by using:
You have several points. Let's use (1,5) and (2,2)
= 2
= 5
= 2
= 1
= = -3
The slope (m) is -3.
y = -3x + b
Now, find the y-intercept.
Substitute points in for y and x.
Let's use (1,5) (x,y)
x= 1
y=5
5= -3(1) +b
5 = -3 + b
b = 8
Add b to your equation.
y = -3x + 8
3/12 = x/16 (multiple both sides by 16)
48/12 = x (simply left side)
4 = x
