Answer:

18: x=98 y=38

19: x=20 y=50

Step-by-step explanation:

To figure out figure 18 you would first figure out x and a triangle equals 180 so 180- (36+46) which is 180-82= 98 and then there are vertical angles between the right and left side so x is equal to one of the angles on the right so 98+44= 142 and 180-142= 38

Then to figure out figure 19 you would first find y by adding 39 and 91 to get 130 and 180-130=50 and then 180-91 (for the angle in the bottom right for the left triangle) is 89 so 89+71=160 and 180-160 is 20.

Answer:

x = 4/(11y)

Step-by-step explanation:

22yx = 8

Solve for x so divide each side by 22y

22xy/22y = 8/22y

x = 4/(11y)

Please Help. Tristen is building 3 trophies using Legos. He needs 324 total Legos. Tristen uses 220 Legos for the largest trophy
velikii [3]

Answer:

1. The equation is given as

324 = 220 +135 + C

2. We have 166 As the correct answer but is not in the option

Step-by-step explanation:

We are been given the following values

No. of trophies = 3

Total Legos required for all trophies = 324

No. of Legos for largest trophy(A) = 220

No. of Legos for smallest trophy(B) = 135

No. of Legos required for final trophy(C) which is unknown

Total legos will addition of everything

Total Legos = [Number of Legos for largest trophy(A) + Number of Legos for smallest trophy(B) + Number of Legos required for final trophy(C)]

Substituting the values

324 = 220 +135 + C

Making C subject of formula

324 = 355 + C

324 - 355 = C

-31 = C

135 + 31 = 166

We have 166 As the answer
