Donna wants to make trail mix made up of almonds, walnuts, raisins. she wants to mix one part almonds, two part walnuts, and three parts raisins. almonds cost $12 per pound,walnuts cost $9 per pound, and raisins cost $5 per pound. Donna has $15 to spend on the trail mix. determine how many pounds of trail mix she can make.[ only an algebraic solution]

Answers

almons:walnuts:rasins=1:2:3

x=pounds of walnuts
y=pounds of almonds
z=pounds or rasins
2x=y
3x=z
subsitute

12x+9y+5z=15
12x+9(2x)+5(3x)=15
12x+18x+15x=15
45x=15
divide by 45
x=1/3
so
1/3 pound of walnuts
2x=y
2(1/3)=y=2/3
2/3 pounds of almonds
3x=z
3(1/3)=z
1=z
1 pound of rasins

1/3 pound walnuts
2/3 pound almonds
1 pound rasins

In an isosceles triangle , one angle measures 20 degrees. What are the measures of the other two angles.80 and 80 degrees
90 and 90 degrees
20 and 140 degrees
20 and 60 degrees

Answers

Answer:

Other two angles are 80 and 80 degrees

Step-by-step explanation:

In an isosceles triangle , one angle measures 20 degrees.

In an isosceles triangle two angles are equal

In a triangle , we have three angles

one angle is 20 degree. sum of angles in a triangle is 180 degree

other two angles is equal to 180 - 20 = 160

other two angles are of equal degree so we divide by 2

160/2= 80

Other two angles are 80 and 80 degrees

80+80=160+20=180

triangles should always equal 180

Factor completely 9ab + 12ax − 6b − 8x.Prime

(3b − 4x)(3a − 2)

(3b + 4x)(3a − 2)

(3b + 4x)(3a + 2)

Answers

Okay so you split 9ab + 12ax - 6b - 8x
             into two 2-term polynomials
              + 12ax + 9ab   and     - 6b - 8x
             doesn't look that good to me so lest try other one :
             9ab + 12ax   and     - 6b - 8x
             looks good for now

            Pull out from each binomial separately
             9ab + 12ax   =   3a • (3b + 4x)
              - 6b - 8x   =    - 2 • (3b + 4x)

           Add up to arrive at the desired factorization so now you have
             (3a - 2) • (3b + 4x)
