The correct option would be the 4th option
Answer:
12
Step-by-step explanation:
Given that :
Point X on number line 1 from 0= 2/3
Point Y on number line 2 from 0 = same distance as point X on number line
Point Y has a denominator of 8 ; the numerator is thus;°
Let denominator = d ; Fraction becomes 8/d
Thus `
Point X on 1 = point Y
2/3 = 8/ d
2d = 3 * 8
2d = 24
d = 12
Answer:
x = 7 cm
Step-by-step explanation:
The two triangles are similar so ...
x/(6 cm) = (42 cm)/(36 cm)
Multiplying by 6 cm, you get ...
x = (6 cm)(42 cm)/(36 cm) = (6 cm)(7/6)
x = 7 cm
