The label on antifreeze container claims to protect the car between -40 celsius and 140 celsius to convert celsius temperature to fahrenheit temperature the formula is c=5/9(f-32). write a compound inequality to determine the fahrenheit temperature range at which the antifreeze protects the car.

a. -40 < 5/9(f-32)
b. 5/9(f-32) < 140
c. -40 > 5/9(f-32) > 140
d. -40 < 5/9(f-32) < 140

In the proof of the triangle angle sum theorem, you must draw an auxiliary line. which construction must you use to draw this line?

The marked price of an article is 25% above its selling price and the cost price is 30% less than its marked price . find the discount percent and gain percent. only a brainlest can solve it i will mark you brainlest

What is the next step in the given proof? choose the most logical approach. a. statement: m 1 + m 2 + 2(m 3) = 180° reason: angle addition b. statement: m 1 + m 3 = m 2 + m 3 reason: transitive property of equality c. statement: m 1 = m 2 reason: subtraction property of equality d. statement: m 1 + m 2 = m 2 + m 3 reason: substitution property of equality e. statement: 2(m 1) = m 2 + m 3 reason: substitution property of equality
