Answer: See explanation
Step-by-step explanation:
You didn't give the options but let me help out. We are told that a certan tile pattern had 6 triangles for every 20 squares.
The ratio that represents an equivalent ratio will be:
6 : 20 = 6/20 = 3/10 = 3:10
Y + 5 = -2 Mathematical equation that represents this problem.
y = -7 Subtract 5 from each side.
Answer: y = -7
Answer/Step-by-step explanation:
1. <ABC and <BCD are alternate interior angles. Alternate interior angles are equal, therefore, since m<ABC = 38°, then m<BCD = 38°
2. m<ECF = m<BCD (corresponding angles)
m<ECF = 38° (substitution)
3. m<DCF + m<ECF = 180° (linear pair)
m<DCF + 38° = 180° (substitution)
m<DCF = 180° - 38° (Subtraction property of equality)
m<DCF = 142°
A) first choice because for x=0 the y= 5 and for x=2 the y=3
Answer:
the student put the wrong setup equation
leading the student to wrong answer
the student should have had it as
5x = 100
Step-by-step explanation:
then divide by 5
