If a copier contains 60% letter-size paper and 40% legal-size paper, what is the ratio of letter-size paper to legal-size paper?
Vladimir79 [104]

Answer:

The ratio is 3/2 or 3:2

Step-by-step explanation:

we know that

To find out the ratio of letter-size paper to legal-size paper, divide the percentage of letter-size paper by the percentage of legal-size paper

so

\frac{60}{40}

Simplify

\frac{60}{40}=\frac{6}{4}=\frac{3}{2}

therefore

The ratio is 3/2 or 3:2

Write an equation in slope intercept form for the line that passes through (-20,-6) with slope m=1/4
brilliants [131]
We start with the equation y-y1 =m (x-x1) because we have m the slope = 1/4 and a point on the line with the coordinates (x1=-20, y1=-6) so, 
 
y+6=1/4 ( x+20); 
y=(1/4)x + 20/4 -6; 

y= (1/4)x -1 and this is the equation in slope intercept form y=mx +b  where the lope m= 1/4 and b= -1 the y-intercept

Answer <span>y= (1/4)x -1 </span>

Determine whether the two expressions are equivalent. Explain your reasoning.
dlinn [17]
Let us evaluate each pair of expressions one at a time.
8. (n²+4) - n² and 4n.
    (n²+4) - n² = n²+ 4 - n² = 4 which is not equal to 4n.
    NOT EQUIVALENT

9. 3x + 5 and  2(x + 3)
    2(x + 3) = 2x + 6  which is not equal to 3x + 5.
    NOT EQUIVALENT

10. 15 - 6x and  15(1 - 6x)
    15(1 - 6x) = 15 - 90x which is not equal to 15 - 6x
    NOT EQUVALENT

11. (y + y + 2 + y) + 3y and 6y + 2
    (y +y +2 + y) + 3y = y+y+y +2 + 3y = 3y + 2 + 3y = 6y + 2.
    It matches the other expression.
    EQUIVALENT

12. 8y - 3 + 10y and 3(6 - 1)
    8y - 3 + 10y = 8y + 10y - 3 = 18y - 3
    3(6 - 1) = 3(5) = 15
    The two expressions do not match.
    NOT EQUIVALENT.

Answer: Only the expressions in number 11 are equivalent.
