Answer: 2 numbers are 19 and 39
Step-by-step explanation:
<em>y = x + 20</em>
Equation: x + y + 20 = 78
⇔ x + y = 78 - 20
⇔ x + y = 58
⇔ y = 58 - x
So, we have:
x + 20 = 58 - x ( = y)
⇔ x + x = 58 - 20
⇔ 2x = 38
⇔ x = 19
⇒ y = x + 20 = 19 + 20 = 39
Answer:
d. C. 4; enlargement
Step-by-step explanation:
Scale factor = Ratio of one of the side length of the scale diagram to the corresponding side length of the original diagram
Side length of scale diagram = 8 units
Corresponding side length of original diagram = 2 units
Thus:
Scale factor = 8/2 = 4
Scale factor = 4
Since it's an while number, it implies that it is an enlargement.
