A low calorie dinner has 480 calories in an 9 ounce serving. What is the unit rate in simplest form? 9/48 160/3 48/9 3/160

LenaWriter [7]

Answer:Hi, the correct answer is $\frac{160}{3}$ .

Step-by-step explanation:

As you are being asked for rate and the importat value is the number of calories consumed. We need to simplify the fraction $\frac{480 calories}{9 ounce}$ . Then we simplify.

Note that 480 is divisible by 3 and 9 as well. 480/3 = 160 and 9/3 = 3. Therefore, 480/9 = 160/3.

M<2=4x+12 <br> Someone help

Katarina [22]

X=12. So this one says that it has 3 congruent sides so therefore it has to have 3 congruent angles. Here we have angle 2 and we have angle 60. Given the definition of triangle congruence, we can say that 60 is angle 2 and that the third angle is also 60 but it’s not relevant in this problem. So knowing that angle 2 is 4x+12 we solve for x by seeding that equal to 60 and then solving for x we get x=12. Hope this helps!!!!
