Question 16
Vadim26 [7]

Answer: 175

Step-by-step explanation: total = x + 5y dollars and dollars = 300 so

x + 5y = 300 then since we know y =  200 we can substitute that

x + 5(200) = 300 then subtract x from 200

x + 5(200 - x) = 300 now solve for x

x + 5(200) + 5(-x) = 300 we know 5 times 200 is 1000

x + 1000 - 5x = 300 then subtract 5x - x = -4x

-4x + 1000 = 300 switch around 1000 and 300

-4x = 300 - 1000 subtract 300 - 1000 = -700

-4x = -700 multiply

x = -700/(-4) then finish up and solve

x = 175

Angle ABD and angle BDE are supplementary. Find the measures of both angles.
marishachu [46]
By definition of supplementary angles,
∠ABD + ∠BDE = 180
5x + 17x - 18 = 180
22x = 198
x = 9

∠ABD = 5(9) = 45°
∠BDE = 180 - 45 = 135°

step 2.

2nd pic:

Rene should add, not multiply 2 volumes.

The correct answer is 48+216 =264

3rd pic:

a, for blue prism: V = Area of base x Height = 48 x a =720

=> a = 720/48 = 15

b,  for orange prism: V = Area of base x Height = (12xb)/2 x 15 =720

=> b =(720x2)/(15x12)= 8
