Answer:

{x,y} = {10,2}

Step-by-step explanation:

Solve equation [2] for the variable  y

[2]    y = -2x + 22

Plug this in for variable  y  in equation [1]

[1]    x - 5•(-2x+22) = 0

  [1]    11x = 110

Solve equation [1] for the variable  x

  [1]    11x = 110

  [1]    x = 10

By now we know this much :

   x = 10

   y = -2x+22

Use the  x  value to solve for  y

   y = -2(10)+22 = 2

Bracelet cost = b
Necklace cost = n

15b + 8n = 500
19b + 24n = 980

Elimination method x -3
-45b - 24n = -1500
19b + 24n = 980

-26b = -520
b = $20 bracelets

Plug back in
19(20) + 24n = 980
380 + 24n = 980
24n = 600
n = $25 necklaces


Check:
15(20)+ 8(25)= 500
300 + 200 = 500
500 = 500 :)

If the volume of the right prism shown is 27 ft3, then h = __feet.
konstantin123 [22]

Answer:

h=6

Step-by-step explanation:

To find the volume of a right angle prism-

Find area of cross-section, in this case an isoscles triangle so we know that both of the parallel lines are 3ft

To find the area of the cross-section, do:

3 x 3 = 9

9 ÷ 2 = 4.5 (Area of cross-section)

Since we don't know the length of h, we need do:

27^3 ÷ 4.5 = 6

Therefore 6 is h

Hope I explained it okay:)

What is this! I will mark u as branilyst
stellarik [79]
The answer is -6

because the triangle angles must measure to 180 and the scalene triangle states that the base angles add up to 86. Subtract 86 from 100, you get 94. Angle two is 94. 94-100=x
