Answer:
n = 9.2
Step-by-step explanation:
Isolate the variable by dividing each side by the numbers that do not contain the variable
Answer:
x = 52
y = 38
Step-by-step explanation:
Angle x is supplementary to a 128º angle.
Supplementary angles add to 180
x+128 = 180
Subtract 128 from each side
x+128-128 = 180-128
x =52
Angle x and y are complementary.
Complementary angles add to 90
x+y =90
52+y =90
Subtract 52 from each side
52-52 +y = 90-52
y = 38
Answer:
35
Step-by-step explanation:
Make equations, l = w+5 and 2l + 2w = 150
Substitute w+5 into 2l + 2w = 150
Simplify to get 4w + 10 = 150
Subtract 10 from both sides to get 4w = 140
Divide both sides by 4 and you get 35 as width
Answer:
It simplifies to 2x + 2.
Step-by-step explanation:
Let the number be x, then the expression is
x + 5 + (x - 3)
= x + 5 + x - 3
= x + x + 5 - 3
= 2x + 2.
