Answer:
280.5 mm^2
Step-by-step explanation:
scale * 25.5 mm = 127.5 mm 1275/25.5 = 5 scale factor
25.5 * 55/5 = 280.5 mm^2
The constant variation of y=15x is 15 and the constant variation of y=8x is 8 :)
With Elimination system:
Substract -4x + y = -1 with -2x + y = 1
and... the result: 2x = 2, so x = 1
Subtitution: -2x + y = 1
⇔-2 . 1 + y =1
⇔ -2 + y = 1
⇔y = 3
The final answer is D ( 1, 3)
Answer:
B) Subtraction Property of Equality
Step-by-step explanation:
To get m∠B=77º, the problem subtracted 103º from both sides of 103º+m∠B=180º.
The Subtraction Property of Equality states that if x=y, then x-a=y-a.
In this case x=103º+m∠B, y=180º, and a=103º.
