2x + x + 33 = 90
3x + 33 = 90
3x = 57
x = 19
Angle 1 = 38°
Angle 2 = 52°
Adding a negative is same as subtraction
-5+78-32
73-32
41
Answer:
Saw this question before. The answer is Anita' square.
Square has only four sides while the others more than four so make sense for the square to have longer sides
Answer:
x = 2, y = 1
Step-by-step explanation:
- 7x + 5y = 19
- -7x - 2y = -16
Use the elimination method to solve the system of equations. Add the terms from top to bottom. 7x and -7x cancel out.
0 + 3y = 3
Divide both sides by 3.
y = 1
Substitute 1 for y into the first equation.
7x + 5(1) = 19
7x + 5 = 19
Subtract 5 from both sides.
7x = 14
Divide both sides by 7.
x = 2
Left:
180-53 = (8x-9)
127+9 = 8x
136 = 8x
x = 17
Right:
(15x+29) = (26x-4)
29+4 = 26x-15x
33 = 11x
x = 3
