PLS HELP I NEED ASAP DUE TODAY 1.Which variable expression is a translation of the word phrase "three less than the product of a number and six"? 3−6n 6n−3 6(3−n) 6(n−3) 2.Fatima is three times the age of her younger sister Melody. Which expresses both ages in terms of Melody’s age m? Melody: m3 Fatima: m Melody: 3m Fatima: m Melody: m Fatima: 3m Melody: m Fatima: m + 3 Assessment navigation 3.A triangle has sides of length 10, 8, and y inches. Which is an expression for the perimeter of the triangle, and what is the perimeter when y = 7? y(10+8) The perimeter is 126 inches when y = 7. 10(y+8) The perimeter is150 inches when y = 7. 8(10+y) The perimeter is 136 inches when y = 7. y + 10 + 8 The perimeter is 25 inches when y = 7.

1. 3 − 6n

2. Melody: m Fatima: 3m

3. i. Perimeter = y + 10 + 8

   ii. The perimeter is 25 inches when y = 7

Step-by-step explanation:

1. Let the number be represented by n, thus the product of  the number and 6 is 6n.  Since 3 is less than 6n, therefore: 3 - 6n is the appropriate expression.

2. Let Melody's age be represented by m, Fatima is three times Melody's age implies 3m. So that Melody's age is m, while Fatima's age is 3m.

3. Length of the sides of the triangle in inches are 10, 8 and y.

Perimeter = addition of the length of sides of the triangle

                = 10 + 8 + y

When y = 7,

Perimeter = 10 + 8 + 7

                 = 25 inches

seems like d

step-by-step explanation:

step-by-step explanation:

the original amount doesn't ''re just looking for the time it takes for 1/2 of the substance to we have

(1/2) =)     take the ln   of both sides

ln (1/2)   = )   and we can write

ln(1/2) = ) lne     and lne   = 1     so we have

ln(1/2) = -.1092t     divide both sides by -.1092

t = ln(1/2)/-.1092 = about 6.347 days = about 6.3 days (rounded)
