Answer:
The answer to your question is: 32 x + 2y - 107
Step-by-step explanation:
Simplify 5+2{y-4[3x+7(2-x)]}
5 + 2 { y - 4[ 3x + 14 - 7x ]}
5 + 2 { y - 12x -56 +28x }
5 + 2y - 24 x - 112 + 56x like terms
32 x + 2y - 107
Answer:
The absolute value of 3/8 is also 3/8.

Answer:
y=0
Step-by-step explanation:
R=3x+9y
(given)
21=3(7)+9y
21=21+9y
9y=21-21
9y=0
y=0

Step-by-step explanation:
Answer:
x = 21°
Step-by-step explanation:
opposite angles are equal
therefore, (3x + 1)° = 64°
open the brackets
3x + 1 = 64
3x = 64 - 1
3x = 63
divide both sides by 3
x = 21°
