So the equation C=5/9 (F-32) is the formula to find Celsius when we have Fahrenheit, so we need to rearrange it to F=C(9/5)+32
then sub both Celsius values in the formula
F=-30 (9/5)+32
=-22
F=130 (9/5)+32
=266
to the antifreeze protects the car between -22°F and 266°F
Answer:
5
Step-by-step explanation:
First, we want to ask "What number divided by 7 <em>is </em>800?" That'll give us a jumping off point to answer the rest of the question.
If dividing some number by 7 gets us 800, that means that <em>multiplying </em>800 by 7 should get us back that number. We find that 800 x 7 = 5600. The first number higher than 5600 is 5601, which, when divided by 7, gets us about 800.14, a number greater than 800. So the lowest whole number that makes the inequality ? ÷ 7 > 800 work is 5601.
Answer:
20/155
Step-by-step explanation:
its b as the slope of the line is constant so it's 2.
