Answer:
D 98°
Step-by-step explanation:
180-82 = 98 or the long way
3x+5 = 180-82
3x = 93
x = 31
3(31) + 5 = 98
Answer:
The area is multiplied by 4
Step-by-step explanation:
4x4=16 (area 1)
4(x2)x4(x2)=64 (area 2 (with the measurements doubled)
64/16=4
615 ≈ 600 (nearest hundred)
Answer:
x = 
Step-by-step explanation:
Given
3x + k = c ( isolate the term 3x by subtracting k from both sides )
3x = c - k ( divide both sides by 3 )
x = 
B=x-5
To get x on its own you have to add 5 to both sides. This gives you:
b+5=x
or
x=b+5
